DAEWOO Gas Boiler Error Codes

Error E0 - The temperature sensor is defective (room remote control).

Error E1 - Insufficient water volume in the heating system.

Error E2 - Faulty flue gas output.

Error E3 - The boiler overheats.

Error E4 - Chimney obstruction. Check the condition of the chimney. Do a cleaning if necessary.

Error E5 - Excess of ignition voltage.

Error E6 - Gas leakage possible.

Error E7 - Communication failure.

Error E8 - Damage to the heating sensor of the heating system.

Error E9 - Connected by water leakage from the heating system.

Error 4U1 - The control panel buttons are falling.

Error U0 - The unit needs to be restarted.

Error EF - The water flow switch exceeded the work for more than 90 minutes.

Error EA - The signal for filling with water in the heating system occurs more than five times in one minute.

EC error - Incorrect choice of modification of the unit.

Error EE - The fan stopped working. There is a problem with the power grid, a malfunction of the fan, condenser or speed sensor. Carry out a check of the electrical voltage, engine performance, capacitor, speed sensor and control board. To eliminate these reasons, replace faulty parts.

Error Ed - A current frequency deviation occurred.

Error U8 - The DHW temperature sensor (hot water supply) is damaged.

Error U9 - Chimney clogging or malfunction with chimney temperature sensor.

The dual-circuit pot Daewoo 100 suddenly began to knock out the machine gun. I disabled the pump DMP 7535 on the board and determined that it was damaged. The unit stood off for a week. Put a new pump 5070. The pump is running, the fan is running. Something snaps as usual, and after a click the flame does not light up and so 3 times. Then the console signal sounds, the temperature flashes on it, and after stopping the tap stops blinking, it does not give an error.

 

A beep indicates low or no gas.

 

Wall-mounted boiler Daewoo Gasboiler DGB 160 MCS. It only works for heating. The error E4 stands out steadily. The fan turns on, but the gas does not come on. If you remove the cover from it, then everything works well. In operation less than a month. Tell me what to do?

 

Error E4 is a fault in the chimney outlet. Possible reasons - either a fan or a question in the chimney itself.

 

Model DGB-100 MSC. When the boiler is not working, the pressure drops. What's the reason?

 

The cause of the pressure drop may be a leakage of water in the system. We recommend that you check the heating system for leaks.

 

In the apartment, the wall gas boiler Daewoo Gasboiler DGB-100 MSC, often the pressure drops. In the manual raise, then it again falls, plus water flows from the valve. What to do?

 

Check the operation of the expansion tank.

 

The boiler of Daewoo Gasboiler was installed. During operation, pressure gradually increases - for 6-7 hours from 1.2 to 2.2 Bar, after which it is necessary to bleed water from 0.5 to 1 liter, i.e. 4 times a day. If you do not check, the pressure rises to a red mark and the safety valve is triggered.

 

It is necessary to replace the elastics on the make-up tap. The reason is not the correct use of the make-up tap.

 

Has made repair of the boiler 250 mcs. After replacing the three-way valve, he began to behave strangely. Periodically ignited only with a third attempt, after one time does not light up at all and gives an error U0.

 

Error U0 means that the flame sensor does not see the flame. Maintenance is required, possibly replacing the flame monitor.

 

I had a problem with the Daewoo boiler dgb 160 msc. Turned on, an error e1 and a pressure of 0.0 bar are shown on the console. What to do?

 

Error E1 - lack of water in the system. We recommend adding water to the system.

 

Dgb 130 msc produces an error E3. The air was removed from the system by means of a Mayev crane. But the unit does not work in heating mode, it gives an error E3 after 5 minutes. In technical support they said it was air in the pump. How to remove air from there?

 

Maybe the reason is in the auto-air valve. Also check the operation of the circulation pump. Error E3 - overheating, no circulation.

 

Faulty boiler Daewoo Gasboiler dgb 200 msc. DHW is turned on 40 degrees. When you turn on the hot water, the burner burns for 10 seconds and then extinguishes for 5 seconds, then again 10 seconds lit, 5 seconds off, etc. From the tap is flowing then warm, then cold water (but not hot). Periodically gives an error E3. The pump is running. What could be the problem?

 

Error E3 - water flow in the DHW circuit. Most likely, the secondary heat exchanger is clogged, or the gas pressure is incorrectly set.

 

Double-circuit boiler Daewoo dgb 200 msc. You turn on hot water - it goes cold, and heating batteries are heated, heating is off.

 

The three-way valve may be defective, there is no switching. Check the operation of the 3-way valve.

Model DGB 130 MSC. The remote control has a hot water temperature of 35 degrees. When the water is turned on, the temperature starts to rise to 90 g., Then turns off and falls to 85 and then turns on again, etc.

 

Most likely, the DHW heat exchanger or a too small outlet water flow is blocked.

 

Gas wall boiler Daewoo DGB-200. After turning off the hot water it switches on spontaneously (there is no water pumping) and turns off after heating the water to 92 g., After a few seconds, re-activation, and so it may take several minutes (when I notice, then disconnect it on the control panel). The replacement of the flow sensor did not change anything. The unit is also turned on in this mode after it is turned on in the remote control in the "hot water only" position.

 

We recommend the replacement of the flow sensor assembly, or replace the control unit.

 

The room controller gives an error E1. What is the reason?

 

There is no water in the unit or the pressure switch sensor is broken.

 

Gas boiler Daewoo gives an error E8, the water heats, and the heating does not work, pressure jumps. What to do?

 

Defective control board or temperature sensor.

 

Model DGB-130 MSC. When operating in the DHW mode only, the pressure drops. In work with heating, the pressure is held. What could be the reason?

 

Check the make-up tap.

 

The unit itself turned off and shows an error E1. What to do?

 

Add water to the heating system.

 

Gas boiler Daewoo 350, heating area 250 sq.m. Do I need an additional expansion tank?

 

The additional expansion tank depends not on the capacity of the apparatus, but on the volume of the heating system. From this, it is calculated. Most often an expansion tank is required.

 

In the system boiler DGB-130. I worked for many years. Suddenly both fuses burned. The autopsy revealed: the circulation pump went out of order, because it gave off a sharp smell of burned wiring. Installed a new pump DDP-7525. After working several days the situation repeats: fuses burned, the pump smelled of burning and smoke went. If you disconnect the pump from the power supply, the fuses do not burn out. What could it be? Is it possible that no luck, and caught a new pump with a marriage or maybe even a reason?

 

If the pump fails, in most cases the control board will burn out. In the future, the board burns the pumps.

 

Daewoo Gasboiler DGB-160. The burner does not light either for hot water or for heating. After turning on the hot water or heating mode, it tries to start three times, after the control lamp flashes and the error codes do not flash. He opened the lid and brought his hand to the fan of the burner - it instantly lit. When I removed my hand, it went out. Tell me, what could be the reason?

 

Possible causes: insufficient gas pressure, adjustment of the gas valve, incorrect design of the chimney, excess air. We recommend checking the inlet gas pressure, the minimum and maximum gas pressure on the injectors, and cleaning the fan.

 

On the boiler dgb 250 msc I expose 65 degrees. As soon as it is typed 65 degrees, it stops and then only works on heating the water. Sometimes stops, and all the time heats the water instead of heating the heating. Batteries during this time become cold. What could be the reason?

 

Probably, the three-way valve is faulty, or you have high-speed heating activated, or the filters on the heating system are clogged.
