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.
We are planning to install a Master Gas Seoul gas boiler in a country house. 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, mechanical cleaning (preferably fine) is required. 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, the main gas can 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? According to the 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 wall-mounted boiler Seoul 16 is in operation. The hot water supply circuit does not work: cold water runs 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 looks like 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 domestic water heating mode did not jam, then there are only a few possible options: a 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.
