Operating modes of gas wall-hung boilers Master Gas Seoul

Gas wall-mounted units Master Gas Seoul No. 14, 16, 21 allow different operating modes: heating and HBC, only HBC, frost protection, emergency mode and timer mode.

1. Heating and DHW mode is automatically activated when the unit is connected to the power supply and the "power" button is pressed. The display shows the corresponding icons, which are detailed in the instructions for each model. The adjustment buttons set the required temperature parameter in the heating circuit. Pressing the buttons leads to a blinking indication of the temperature of the coolant. The end of the setting leads to automatic maintenance of the boiler on and off.

Mode change is made by a special button "mode selection" on the control panel.
Setting the temperature value for the HBC circuit is made with a special button. The parameter value selected as the main one is displayed on the right side of the LCD screen. The accuracy of setting the temperatures falls within the range: from 37 to 45 degrees, the takeoff run is + 10C, from 45 to 600C, the takeoff run up to + 50C is possible.
Automatic feeding hot water occurs from the moment the hot tap is opened.
Closing the tap automatically puts the system into heating mode.

2. Activation of the frost protection mode is set by pressing a special button.

The mode takes effect from the moment the temperature drops below + 50C.
The burner turns on at the inlet and works until the temperature of the water rises to 400C.
The protection mode is used in the event of a long absence of the tenant in the house, as an economical mode in terms of gas or electricity consumption.

3. The mode of switching on only DHW, with the heating mode turned off. This mode allows you to use the boiler in the summer as a gas water heater... When the GBC mode is set, the boiler operates to produce hot water.

The transition is made by pressing the "mode selection" buttons until the indication disappears from the screen and the temperature indicator in the HBC circuit blinks. The plus / minus buttons set the selected temperature parameter. The error of the value depends on the run-up of the temperature range and ranges from 10C to 50C.

4. The timer mode provides for the cyclical operation of the installation. The cycle lasts 15 minutes, then there is a pause in the operating mode.

The duration of the pause is set by the owner independently from 1 to 6 hours.
During operation, the water heats up over 80C.

5. Emergency operation.

This mode is intended for a short period of time, for extraordinary cases: failure of the control panel, malfunctions in the heating system, when the pressure of gas and water drops.
The transition to the mode is made when the faulty remote control is disconnected and the wires are connected to each other.
The boiler starts operating in the heating and HBC mode, the set temperature in the circuit is maintained.

Troubleshooting methods for boilers Master Gas Seoul

Gas boiler Master Gas Seoul. The gas pressure in the line has disappeared. Tell me, does it restart automatically after pressure builds up?

The unit will make several attempts to start, if there is no flame, it will go into an error that can be reset manually. There is a special minimum gas pressure switch for automatically starting the device when pressure appears in the gas line.

We use the Master Gas Seoul 14 boiler at the dacha. Until tonight it worked without interruption. But now he has a problem. The device very often goes into overheating. How can this accident be repaired?

Scale has probably built up, so the duct is clogged. You need to clean the device.

The day before yesterday there was a malfunction. The device turns on, but the heating does not heat up. What could be?

It is possible that air accumulates in the batteries or excess scale in the heat exchanger. It needs to be washed.

Planning in country house install the Master Gas Seoul gas boiler. Please tell me how many watts standard e-mail. the power of this apparatus?

Based on the instructions, the nominal electrical power for these versions of the unit is from 80.0 to 160.0 watts.

Why are filters installed?

By purifying water and gas, filters extend the life of the boiler. One must be installed on the pipe supplying cold water to the unit. Due to the deterioration of public utilities, water contains an excessive amount of iron; rather large particles can be present in it. In order not to let them inside the boiler, it is required mechanical cleaning(preferably thin). There are chemical filters that
prevent the formation of limescale in the heat exchanger. It is also recommended to purify the water entering the device from the return pipe from its own heating system. Just like water main gas may contain mechanical impurities. A filter for it is installed in front of the gas meter or directly in front of the apparatus.

Installed gas wall-mounted boiler Master Gas Seoul 16 double-circuit. A question of the following nature, for what reason can it knock when switching from heating to hot water supply?

In your case, the whole problem is in the three-way valve, you need to replace it.

The gas wall-mounted boiler Master Gas Seoul 16 is connected. Help with advice: the pressure at the minimum mark (about 1 mbar) at the moment the make-up valve is opened, the pressure does not rise, and if it rises, it is insignificant (1.1 mbar). What is the cause of the problem? In addition, it makes a rather loud noise. The pressure in the water supply is 4.5 atmospheres.

Regarding the first, it could have clogged the make-up system, it is necessary to see what, how does the expansion tank work? As for the second, if it makes a noise, it is necessary to find out what exactly the pump is or the heat exchanger is clogged.

Malfunction at the Master Gas gas boiler. It flashes the AA error all the time, in rare cases A4. It turns out that it is boiling, while, when it starts to boil, the heating pressure gauge begins to go off scale. The water pressure through the apparatus is two times worse than cold water. What could be the reason?

If it boils, then there is poor water flow, it is necessary to look at the system or the primary heat exchanger is clogged. The fact that the pressure rises, so it will be, because when boiling it rises. Take a look at the hot water heat exchanger.

We operate the gas boiler Seoul 14. Give advice. Based on the technical passport, for the device, the minimum flow of water in the system for switching on in hot water supply mode is 2.5 liters of water per minute, and in my case it turns on with a water flow of 7 liters per minute. Plus, this increases water consumption. Service workers say you can't do anything. Is it really so?

It is possible that the indicator of the hot water supply duct wedges, if it works, then disassemble and check. It's not difficult there, or it may be with a factory defect.

Malfunction of the gas boiler Master Gas Seoul 21. Installed six months ago, worked flawlessly, but in winter it began to emit loud noises, and if you press the lid a little with your hand, the noise dies down. It turned off a couple of times, flashing error A6. But when turned on, it worked fine. But there is noise, I can't understand what it could be? Regarding the noise during ignition. It worked well for 1 year, later it started to hum a little. After the visit of the master, the noise became less. The chimney is installed normally. There was a problem: error A3 started popping up, the device stops, the most surprising thing is that the error pops up at night, during the day everything works fine. I came to the conclusion that the error is somehow related to the pump. What exactly could it be? Error A3 began to pop up often, it worries because the boiler turns off. Who can tell you how to solve the current problem, maybe someone had a similar experience? Is this a pump or fan error?

You should adjust the maximum and minimum gas pressure, and the fan needs to be cleaned. It is recommended to short-circuit the contacts of the water pressure indicator and monitor the operation of the boiler. If error A3 is no longer displayed, it means that the switch on the indicator is malfunctioning, or you have problems with the water pressure.

Tell me about the work of the gas boiler Master Gas Seoul 14. The problem is as follows, when the hot water supply is turned on, hot water enters the heating system, and cold water comes from the tap. The pressure is constantly dropping. The system does not leak, I checked it several times. I thought that the problem was in the 3-way valve, but they say no.

Replacement of the 3-way valve is required. It is recommended to pump air into the expansion tank.

Installed gas wall-mounted boiler Seoul 14 kw. Developers have poured water into the heating system. I had never met such a technique before, so a couple of questions arose. I plan to pour purified water into the system. After reading, I generally figured out exactly how this should be done: pump in with the help of a pump through the accompanying cold water nozzle that goes to the unit, open the feed valve and wait until the required pressure appears in the system. Then, at the same time shut off all this, bleed the air and start the apparatus. During the period of its use, the water will evaporate evenly, respectively, the pressure will drop. In order to raise it, I just need to open the feed tap and the water from the main will fill the system to the required pressure? If you believe technical data sheet
the electronic part of the unit must be connected via a power stabilizer. I would like to know your opinion on this matter, is it not dangerous? I know that there is a board inside, which is afraid of voltage drops. On cold water, I plan to install a filter in front of it. Need advice on which one to choose?

Your heating system has no more than 20 liters. This will not cause problems, unless you add more and more daily. Check that there are no leaks anywhere.

The Master Gas Seoul 16 gas boiler was connected, a malfunction appeared, an error was displayed. It was assumed that the whole problem was due to a clogged gas valve, but after checking it turned out that they were clean. What else needs to be checked?

First of all, it is necessary to check the pressure of the incoming gas, making sure that the gas meter and pressure switch are intact.

A gas wall-mounted boiler Master Gas Seoul 21 is installed. Stopped starting, flashes an ignition error. How can you solve it and what could break?

Ignition error appears when: the gas valve is faulty, the flame detector or the board is unusable, the ignition wire is cut off, the gas pressure is low.

The Seoul 16 wall-mounted boiler is in operation. The hot water circuit does not work: it runs cold water without heating. We have been using it for the first year. What could have happened?

There can be many reasons for the lack of hot water supply. The heat exchanger from the inside could be clogged, or the meter could be out of order, or the three-way valve could jam, and many other reasons. For example, due to voltage surges, the control board could deteriorate.

Gas boiler Master Gas Seoul is connected. I noticed that I started to leak a little at night. I noticed a splash of moisture through the air valve. How do I fix this problem?

Presumably, due to the unsuitability of the expansion tank, the safety valve has failed. It is necessary to replace the expansion tank or the valve itself.

We connected a wall-mounted Master Gas Seoul boiler. The problem is the following, at an exposed temperature of up to 60 degrees, it began to ignite poorly, namely, when it starts to make noise, then makes a couple of attempts to ignite, but not immediately, I wait about half a minute, the nozzle starts to burn, everything is normal. After turning off, everything repeats. But, if you set the temperature to more than 60 degrees, everything works well. The same story with
turning on hot water, you also have to wait a while. Who knows, tell me what is the reason?

Unstable ignition or ignition power depends on the minimum gas pressure at the nozzle. The nozzle must be cleaned. Fan too. Check the mains voltage. The burner pressure must also be adjusted. Look and clean the surface of the heat exchanger. It is recommended to carry out those. service.

Malfunction in the operation of the Master Gas gas boiler. Displays error A5 (low water pressure). The manual says that the normal pressure is 1.5 - 2.0 mbar. The lowest is 0.5. The first year it worked properly, water was pumped through the street water supply. Pumped up as soon as the pressure reached 0.5 mbar. In the second year, they connected it to the well and at the end of the year problems began. As soon as the pressure drops to 1.3 mbar, it gives an error A5. Maybe someone knows, I suppose, that the pressure indicator is malfunctioning. Maybe you need to turn it off and short-circuit the wiring? Or maybe there was acidification of the air vent, earlier it leaked a little, now everything is dry. For the entire period of operation, pressure
falls off very rapidly. I checked all pipes and connections, but did not find a leak. In recent days, the pressure has been 1.5-2.0 mbar (I do the pumping every few days).

1 mbar equals approximately 1 kilogram, the pressure sensor is on the pipe, put a plug between the 2 wires, and it is better to replace or wash it thoroughly.

Installed Master Gas Seoul 14. The device is working properly on the heating system, and when switching to hot water, after a while a hum appears (similar to water sucking), the fire in the device turns off for a couple of seconds. Accompanied by a few seconds upward voltage jump (then comes back). Hot water runs out. After which everything is fine, and approximately in
for half a minute, everything is repeated. Spent those. service, no change. The boiler has been in operation for a little over a year. I cleaned the heat exchanger, the water is ordinary, the master claims that it is harsh. After maintenance, the pressure does not jump and there is no cotton. Hot water flows from the tap, but not for long, then immediately ice cold, and then again slightly warm, then a little hotter and in the same sequence. I noticed that when the fire goes out, the AA error is displayed for a few seconds. There is something wrong with the pump or the three-way valve is malfunctioning.

It is very likely that there is a problem with the hot water heat exchanger. Most likely it needs to be replaced.

It is not possible to switch the boiler from hot water supply to heating, it switches instantly. What is the reason for this?

Which mode is displayed on the panel? Heating or shower? If the heating mode did not jam household water, then there are only a few possible options: malfunction of the flow sensor or problems with the control unit. If restarting didn't help.

Tell me where the tap of the heating system is located and how to properly shut it off? Because the water from the hot water supply circuit is not the same as installed on the panel (much colder). Or maybe someone had a similar situation?

Heating system taps are installed directly in front of the device: at the supply and at the return. The water flow is large and the gas pressure is not high.

The air outlet is leaking and pressure is being relieved. A crane with a rubberized ring is mounted there. What is the normal tap position? Should it be open or closed? If it is to be opened, how is the pressure release to be adjusted or is the valve to be changed? Expansion vessel pressure is normal.

It is necessary to remove the air vent, disassemble and clean.

The gas boiler Master Gas Seoul is in operation, questions arose. I fixed two thermometers next to the control panel and the readings on them coincide, but on the control panel. When the apartment has 22 gr. on the remote control 24gr., and when in apartment 24 there are already 27gr. on the remote control. How can this be corrected? Maybe someone knows how to get into the remote control menu with large rights? Once in the menu, as described in the instructions, it is impossible to change the boiler power, however, like many other settings.

The settings in the remote control become available when you turn on the switch No. 3 on the block.

Malfunction of the Master Gas Seoul 16 gas boiler. We use it for 2 months. Problems with ignition have already appeared. The claps are sometimes so strong that it becomes scary.

Obviously, the gasmen turned on the gas, but did not adjust the pressure.

In general, there are many questions with heating: both a hum and periodically appearing white smoke (steam?) From the chimney, and, what is most unpleasant, a regular drop in pressure in the system. Water has to be added every ten days. There are no visible leaks, it is possible to sin on the inadequacy of the built-in expansion tank (due to lack of funds, I hung up the existing steel panel radiators of Soviet production, so it is quite possible that the volume of the coolant is more than the recommended 50 liters), however, jumps into the red zone and discharges after that extra pascals are not observed ... I don’t want to admit it, but, perhaps, the only, in my opinion, correct assumption is a malfunction of the boiler heat exchanger (crack) due to which water constantly seeps into the combustion chamber, as a result of which the pressure drops in the system, and white smoke comes out of the chimney. I would be very grateful to everyone who gives their opinion.

One of the reasons is that the coaxial chimney is not installed correctly (no slope) and condensate enters the combustion chamber and, again, the gas regulation is not correct.

A 140 kW master gas seoul wall-mounted boiler in a one-room apartment is connected. The developer poured ordinary water into the heating system. I had no relationship with this technique before, so several questions were ripe. I want to fill the system with distilled water. After reading, in principle, I understood how to do this: pump it through the cold water inlet fitting that fits the device, open the make-up valve and wait until the coolant is pumped into the system and, accordingly, the required pressure appears. Then we shut off the whole thing synchronously, bleed the air and start the boiler. Please correct if I am mistaken. During operation, the water will still evaporate a little, and the pressure will drop. To raise it, I just need to open the make-up tap and then the water from the main will replenish the system to the required pressure? According to those. passport, unit
requires to connect the electrical part through a power stabilizer. I want to hear opinions on this, whether this condition is critical. I understand that there is a microcircuit inside that is afraid of voltage drops and yet? I want to put a filter on the cold water main in front of the boiler. Advise, at least which one to choose, maybe special filters are used here?

Your heating system has 20 liters of water. And it won't be a problem if you don't add the same amount or more every day. Better watch for leaks.

When the Seoul 14 gas boiler operates according to the air temperature sensor, it turns out somehow crooked. The sensor is lying and the error is not linear. The temperature in the room ranges from 22 to 24, and on the remote control is 26 (thermometer next to the remote control and away from the battery). During a pause, the batteries cool down completely, and from constant heating-cooling drops, smudges may appear on the reel. We have to adjust the water temperature of the system when working with an air sensor, and in this remote control, unlike Navien, it is not convenient. In general, the temperature in the apartment is more stable, and the batteries are always hot when the boiler is operating according to the water temperature in CO, as long as there are no strong temperature changes outside. Ideally, it would be if the water temperature of the system was adjusted automatically from the air temperature in the apartment! Here's how to do it?

Although theoretically, if you take a PID controller for MEO with a resistance thermometer, connect a boiler by temperature in CO to the buttons of the remote control, it may work out. With a large integration coefficient, the regulator will be more inert, waiting for a change in the signal from the sensor. You just need to think about the circuit that will duplicate the output of the regulator to the remote control button, you need to press the remote button twice.

Tell me what kind of a tap of the heating system is and where can it be turned off? Since the water from the DHW circuit does not correspond to the one set on the control panel (much colder, not even hot by 60 degrees). Or maybe someone came across this?

Taps on the heating system are mounted in front of the boiler - on the supply and return. The water flow is too large. Gas pressure is low.

Adjusted for 11 kW. The pump is making noise and heating. The pump temperature is 2 times higher than that of the media. But the hand suffers. This is fine? Several times gave an error to the pump A3. Where to bleed the air from it? I can't find the cork. Or do you need to open the air vent? And How? Maybe he's running dry?

There is no plug, but you can open the air vent.

The wall-mounted boiler Master Gas Seoul 16 is in operation. Tell me what to do: the pressure on the verge of the minimum allowable (about 1 bar) does not increase when the make-up tap is opened, or sometimes increases slightly (1.1 bar). What could be the reason? And it buzzes very much. The pressure in the water supply is like 4.5 atmospheres, if that.

As for the first, maybe the make-up system is clogged, you need to look at what exactly, how does the expansion tank behave, and does the pressure gauge show exactly? As for the second, if it is buzzing, it is necessary to find out that the pump or the clogged heat exchanger is buzzing. Go to the settings of the remote control value P8 from 31 put 20 in the passport according to the table a typo. The buzz will pass.

Malfunction of the Master Gas Seoul 16 boiler, the AA error constantly pops up, sometimes A4. It turns out that it boils, while when it boils, the pressure gauge for heating goes off scale. The water pressure through the boiler is 2 times worse than cold water. What could be?

If it boils, it means that the water flow is poor, see the system or the Primary heat exchanger is clogged. And the fact that the pressure increases, so it will be, since it increases during boiling, and see the DHW heat exchanger.

The gas boiler is in operation Boiler Seoul 14. Tell me what to do. According to the passport data for the boiler, the minimum water flow in the system for turning on the boiler in DHW mode is 2.5 l / min, and it turns on for me with a water flow of 6-7 l / min (made measurements practically), in addition, this is an increase in water consumption ... The servicemen say that nothing can be done. Is not it?

Maybe the DHW flow sensor wedges, if it is possible to disassemble it and check it, I think there should be nothing complicated there, or it may be defective.

I called the serviceman from the gas department. The problem was solved by adjusting the maximum pressure. However, with the recommended value of 55, I had to set 40, otherwise the hum would not go away. Again, it is not clear how this will affect the set and maintenance of the set temperature in winter. And it turns out that these models also regularly, about once a year, the valve for switching from heating to hot water is damaged.

The primary heat exchanger is clogged. Flushing is needed.

A gas boiler MG Seoul 14 with a closed heating system was installed and connected, I did not see how antifreeze was poured. In general, after the time elapsed while the gas was being processed, the pressure dropped and the boiler did not start, how to increase the pressure?

Look, there must be a crane, but in fact, you need to ask the people who were doing this, or at least be present at the first start, so that later such questions do not arise, but just look - it must be like that, a pump will be needed.

Malfunction of the gas boiler Master Gas Seoul 21 with a water heater. In December, it will be two years old. Broke 3 times already. Error A4. The heat exchanger was replaced for the first time. They said that he was hammered due to the fact that someone opened some kind of tap there. Moreover, he installed it. In the spring, when the boiler gave the same error, another master came, turned it on, adjusted the pressure, the device started working on its own. Now again this error. We have already washed the previous heat exchanger in case of replacement. We have water filters at the inlet. Tell me this is the norm, that in 1.5 years of service we have already repaired it 3 times?

The wall-mounted Master gas boiler is buzzing, how to switch the control board to the service mode, otherwise it does not give from the remote control.

On the board there are three micro toggle switches on top, move the top two to the opposite side and go into the settings, then put them back in place.

Tell me, what could be: the third day, water is dripping strongly from the tube below and the pressure drops? Yes, and air appears in the first battery. Is the air vent clogged? Can I fix it or just a replacement? Kotlu Seoul-14, three months old. Works intensively for a week (frosts), works on air temperature.

Hit the air vent with a screwdriver, it will close and will not drip.

Tell me, the value "setting the fan speed" (forced minimum combustion) in the passport L2 40. Today I compared all the parameters with the passport, L2 is set to 36. Leave it or set it as in the passport?

If the minimum gas pressure on the boiler burner decreases below the value set by the manufacturer, the gas consumption will increase!

Malfunction of the Master Gas Seoul 21 boiler. It was installed in the spring, it worked fine, in the winter it began to hum a lot, and if you press the lid with your hand, the hum disappears a little. Turned off several times with error A6. True, when turned on again, it worked fine. But the hum is present, I don't even know what to do. And by the way, can the hum go due to the fact that the pipes for heating PP 20? Also tell me: what are the P8 settings for 16 kW?

In the passport-20, in fact-31.

Already several times it has torn off the boiler filter (under the pressure gauge). Everything seems to be in order, the pressure in the CO is normal, and it does not give any errors either. Warms ok, according to the settings, and hot water is ok too. Knocked out, screwed the filter back in, added water - everything is all right again. Last year, a friend had the same problems - he finished it until the control board was filled in - they replaced it and everything worked out. The device is already 3 years old - there were no problems - only sometimes it pumped air into the expander. Please tell me what to do?

Does anyone know how the boiler output can be increased? When I was buying a boiler, the seller said that supposedly it was possible to make a boiler from the 16th to 21st with a switch on the board. Is this possible? Do all models have the same controller board? Can you reflash the controller? Anyone clinging to the controller?

Can you tell me where is the plug for air intake from the room?

On the top of the boiler, next to the coaxial on 3-4 self-tapping screws.

Regarding the hum during ignition, it worked normally for a year, after which it slowly began to appear. I called the master, tuned it up, the hum diminished, but did not disappear at all. The chimney is installed correctly. A problem arose: error A3 began to appear, the boiler stops working, and the error occurs only at night, during the day everything is in order. Realized that the error was related to the pump. What could it be? The appearance of error A3 has become more frequent, annoying,
as the boiler shuts down. Who can help solve the problem, or who have not encountered this error? All the same, this error with the pump or fan? The instructions are somehow not clear.

You need to adjust the minimum and maximum gas pressure, clean the fan. Short-circuit the contacts of the water pressure sensor and observe the device, if there is no A3 error, it means that the microswitch on the sensor may simply fail, or something is wrong with the water pressure.

The wall-mounted boiler MG Seoul is in operation. The problem is that at a set temperature of up to 65 degrees, the ignition became poor, namely when it starts to hum, then it tries to ignite several times, but not the first time, I wait 30 seconds, the burner starts to burn, everything is fine. After it turns off, everything repeats. But at a temperature set above 65 degrees, it works properly, lights up clearly. The same when I turn on
hot water, I also wait for some time until the ignition occurs. Tell me what could be?

Poor ignition - or ignition power, depends, among other things, on the minimum gas pressure on the burner, as well as the ionization electrode itself - its purity and position in the combustion chamber. Clean the burner. Clean the fan. Look at the voltage in the network. Check the pressure on the burner, adjust. Look at the surface of the heat exchanger, clean it. Maintenance generally needs to be done.

Malfunction of the Master Gas Seoul boiler. Error A5 (low water pressure). According to the instructions, the working pressure is 1.5-2.0 bar. The minimum type is 0.5. The first season he worked well, and since there was no water supply in the house, the water was pumped from a common street water supply. (as the pressure drops closer to 0.5 bar, it pumped up). In the second season, I connected it to a well (hard water) and by the end of the season, problems began. As soon as the pressure drops closer to 1.3-1.4 bar, error A5 (restarting the boiler without adding water and it runs on for a certain time). Maybe someone will tell me, I suspect that there is something with the pressure sensor. Can turn it off and close the wires (who knows how it works?). Or maybe the air vent has soured, before droplets dripped from it, now it's dry. Throughout the history of use, water pressure drops somehow quickly. I looked through all the pipes and connections, but did not find a leak. That is, recently I have been pumping up the pressure from 1.5 to 2.0 every three days. And yet, the pressure in the empty expansion tank should be 0.09 MPa, how much is it in bars.

1 bar - 1 kilogram approximately, the pressure sensor is on the tube, 2 wiring put a jumper between the wires, and ideally the sensor for replacement or remove and rinse well.

Boiler malfunction Master gas seoul 14. Worked for 2 years 4 months with almost no complaints, the only thing was to regularly add pressure (it dropped constantly, although there were no leaks), and a week ago I switched it to DHW mode, worked a little and issued an A4 error, turned it off from the outlet , turned it on again - it worked. In the morning he turned on hot water, again the boiler hummed strongly, the pressure gauge needle ran up and down and error A4, they say to clean
We need heat exchangers (I have never done this wherever the instructions are, the procedure is how to do it all and it’s not difficult for myself), but when I turn it back on with the heating mode, the whole norm works, why is it?

Help me understand the operation of the Master Gas Seoul 14. The problem is that when the hot water supply is turned on, hot water goes into the heating system, and cold water runs from the tap. And the pressure drops regularly. The system does not run, I checked it several times. I thought about a three-way valve, but I read somewhere that the reason is not in it, but they do not say anything intelligible either.

1. change the three-way valve.
2. Pump air into the expansion tank.

The MG Seoul 14 gas boiler is in operation, it hums when fired up. "On a cold" hum is stronger, on a warm one - less. The walls of the boiler vibrate strongly during hum, if you find a point on the wall and clamp it, the hum becomes an order of magnitude less. The fan is clean. There is a feeling that the hum is directly dependent on the magnitude of the air flow. I suppose the reason is acoustic resonance. Adjusting the fan speed through the settings affects only indirectly and does not completely eliminate the hum.

The humming noise may be caused by a flame blowing off the burner. There are many microslops that resonate at a specific frequency and produce hum. Flame separation, in turn, occurs due to a mismatch between the gas supply (its pressure) and the air speed. I made a pressure gauge, adjusted the maximum and minimum according to the instructions. Boiler performance has changed. After ignition, pressure is gradually added to the cold apparatus. At some point, a hum appears. The device immediately drops the pressure to a minimum and runs on it for several minutes (there is no hum at this stage, sometimes there was before adjustment). Then he starts adding a little pressure again. Again at a certain moment (the pressure approaches 80% of the maximum in the passport) a hum appears. It again lowers the pressure a little, and then slowly increases it again, as if trying to approach the border where the hum arises, but not to allow it to occur. It seems that the "brains" feel the hum, and try to expose the maximum possible pressure without the hum. But how do they feel? I can't see the sensor. Is that a traction sensor. It would seem that the connection between pressure and hum is obvious. When a certain pressure is reached, a hum appears. But no, in heating mode and hot water supply there is almost no hum, although the pressure is almost twice as high as the pressure in heating mode, at which there is a hum.

Water drips continuously from the air vent and the pressure is released. There is a crane with a rubber ring. What is the normal position of this faucet? It must be closed or open. And if it is open, then how to adjust the pressure relief or the valve only for replacement? I'm not afraid to disassemble a trifle, I knocked, tapped and patted with a screwdriver, it still flows. The pressure is normal, including in the expansion tank.

Remove the air vent, disassemble and clean. Somewhere brought up or deposits due to water do not allow the float to fit snugly.

The wall-mounted Master Gas boiler is in operation. For heating, the boiler works normally, I turn on hot water, after 15-20 seconds a noise appears in the boiler (as if it is sucking water), the flame in the boiler turns off for a few seconds. This is accompanied by a second upward pressure jump (then it comes back), hot water, of course, also stops flowing. Then everything is fine, but after 15-20 seconds everything is the same, etc. I did
maintenance, nothing has changed. The device has been in operation for less than a year and a half, the heat exchanger was cleaned, the water was ordinary, the master was, he said it was tough. Now, after the service, there is no pressure jump and clap (at first, although there was, yesterday I wanted to capture this moment and there is no clap of it, the pressure arrow just twitches a little and the flame goes out). Hot water comes from the tap for a short time, then immediately cold, then barely warm, then again a little
hot, further in the same order. I noticed when the flame goes out, the AA error pops up for a few seconds. That is, something with the pump means or damage to the three-way valve, guided by the instructions, because the filter is clean.

It looks like a DHW heat exchanger. Apparently you need to change.

The Seoul 16 boiler is installed and connected, when the DHW is turned on, a crackle occurs in it, the pressure arrow jumps and an A4 error is issued. Need to replace the heat exchanger of the secondary or 3-way valve? Hot water is running, but the boiler goes out and all the error is A4, that is, when you open the tap of the mountains. water, a crackling sound is heard from it, an arrow jumps and the boiler goes out, and it still stood for a week in winter mode, who didn’t touch it and again the floor was a mistake? Temperature on
DHW was installed at 55.

This is overheating of the heat exchanger. In the secondary scale, which prevents the normal transfer of heat from the heating circuit to the hot water supply, that is, it does not heat up to 55, and the device regularly tries to complete the task and raises the temperature, which leads to overheating and the activation of the corresponding sensor, it turns off.
