Electrolux boiler errors, how to troubleshoot

No matter how reliable the technique is, over time it can fail. Each failure is preceded by its own causes. The errors displayed on the displays of the Electrolux boilers help to find them out. The decoding of the codes can be found in the instructions. And we will tell you what steps to take to fix the problem.

The principle of operation of Electrolux boilers

Gas equipment from the Electrolux company is distinguished by a large assortment of models for every taste. Among the boilers you will find double-circuit and single-circuit. The equipment is perfectly adapted to Russian operating conditions. The manufacturer has provided the following points:

  • Interruptions in pressure in the water and gas mains – all devices function stably even at minimum pressure;
  • Frosty winters are not terrible for equipment. The “Anti-freeze” function ensures the constant operation of the device;
  • High efficiency – 94%.

The security system has not been overlooked either. The safety valve will protect against high pressure, the flame sensor – from the extinction of the fire in the burner, the draft sensor – from the ingress of carbon monoxide into the room.

The modern ETC control system makes operation comfortable. The user can adjust the temperature depending on the weather outside. When you leave the house, program the appliance to work at intervals of 30 minutes. This will significantly reduce costs.

The double-circuit mounted boiler is most in demand among users. It provides hot water to taps and radiators.

You can see the device device in the picture below:

The operation of the closed combustion chamber is carried out by a fan, which forcibly removes the combustion products to the street. Accordingly, such systems do not need a chimney.

There are models with an open chamber. They require natural ventilation in the room to maintain the flame, connection to the chimney.

Basic malfunctions and error codes

On the main panel of the boiler there are not only regulators, but also a display. It displays the temperature, as well as fault codes. The electronic control is equipped with a self-diagnosis system. Therefore, if problems occur during operation, an error is displayed on the screen.

How to correct the situation and resume the work of equipment? In the table below, we will present a breakdown of all possible errors, as well as options for solving them.

CodesValueCauses of appearanceHow to fix
E1 (E01)There is no flame.Reduced pressure in the gas line, non-working ignition electrode.What do we have to do:
  • Open the gas valve to the stop;
  • Restart the device. To do this, press the RESET key. If after that the boiler does not turn on, contact the service center;
  • Air locks in the line. You will need specialist help;
  • Examine the electrode. In case of displacement, return it to its place. If it is clogged with soot, clean and continue operation;
  • Check the wiring for integrity, the tightness of the contacts;
  • Diagnose the gas valve. Replace if defective.
E2 (E02)The coolant is overheating.What happened:
  • The tap of the heating system is closed;
  • Large accumulation of air;
  • The temperature sensor is not functioning correctly;
  • Pressure drops in the line;
  • The pump is not working properly or is broken.
Troubleshooting:
  • Turn the valve handle to the open position;
  • Open the air cocks to release air from the pipes;
  • Restart the technique. Did the error code disappear from the display after switching on? Then tighten the contacts from the temperature sensor to the electronic unit. Ring the sensor with a multimeter, replace if broken;
  • Normally, the pressure should be at least 1-1,5 bar. Otherwise, the boiler will not start. Add water to the system, check connections for leaks;
  • The mains voltage is checked when the pump fails. If it does not correspond to the norm, it is recommended to install a stabilizer.
E3The operation of the device is blocked.The security system has been triggered:
  • The chimney is clogged;
  • The contacts of the thrust sensor are oxidized or it itself is faulty;
  • Elements of the main board are out of order;
  • No ventilation in the room;
  • Incorrect chimney installation.
  • How to clean a chimney? In the absence of traction, the hole is checked first. Cleaning is better to entrust utilities. If this is a coaxial chimney, make sure that ice does not freeze there in winter;
  • Clean the sensor contacts, install a new element if necessary;
  • You can inspect the boards yourself. But repairs should only be carried out by a specialist;
  • To operate an open combustion chamber, the room must have a window with a window or ventilation;
  • During the arrangement of the chimney channel, calculations were not carried out.
E4 (E04)The pressure in the heating circuit is below 1 bar.The heat exchanger is clogged with scale. Radiator corroded and leaked.First of all, turn off the equipment, open the fuel valve until the values ​​​​on the pressure gauge begin to correspond to the norm. Then start the device. Did the error pop up again? Then:
  • The abundance of scale clogs the heat exchanger tubes. For cleaning, you need to remove the radiator and remove the blockage with a solution of citric acid;
  • You can fix the leak with a soldering iron. Dry the radiator, prepare solder and seal all holes.
E5The pressure gauge shows increased pressure (more than 2,5 bar).
  • Problems with the operation of the safety valve;
  • The pressure sensor did not work correctly.

Inspect the valve – it should work in a timely manner. Clean the mesh filter, it could be clogged with debris and rust;

If the sensor is shorted, a new part is installed.

E6The hot flow temperature sensor is broken.The sensor is faulty, or there are problems with its wiring, electronic unit.Diagnostics and replacement of broken elements.
E8Damage to the external temperature sensor.Similar actions as with E6.
E9The temperature in the boiler dropped to 2 degrees.To avoid freezing, install a thermometer outside for monitoring.
E10The device is blocked due to the smoke protection operation.Make sure you have traction.
E11Parasitic flame.Air has accumulated, which can be removed by opening and closing the faucet.
E14Pump error.Diagnostics is being carried out.

In addition, in Electrolux models of type 24 Basic Space Duo, the code F4 may appear. This means that the circulation pump has broken down, because the pressure does not exceed 0,1 bar. Replace the device.

The code l01 indicates a blockage in the heat exchanger – descaling is required. And error E7 means a malfunction of the coolant sensor. Or it gives incorrect readings. If the sensor is working properly, the board is checked.

Also, users complain about the noise and squeak in the boiler. Probably too much air has accumulated in the system, or the fan has failed.

Now you have familiarized yourself with all the malfunctions and you can start repairing.
