Westen Gas Boiler Error Codes Error E01 Indicates that there is no ignition. The ionization flame sensor signals a malfunction in the device. This element detects the presence of a flame and stops the operation of the Westen boiler with limited combustion of the main gas burner device or with difficulties with the flow of gas. Functions are interrupted after three unsuccessful activations. To resume operation, it is recommended to keep the reset button pressed.

Gas valve malfunction – The operation of the gas valve is controlled by an electronic board. Diagnostics of this part is carried out by measuring resistance and voltage. If it turns out that the readings differ from the standard parameters, the valve should be replaced. Lack of gas supply to the system – A valve is located in the gas distribution circuit, which limits the flow of gas. As a consequence of this, an accident at the time of starting the boiler may occur due to a blocked tap. Poor contact or no signal from the flame ionization sensor. The electronic board is damaged – If the ignition cycle occurred correctly, but the unit went out immediately anyway, then most likely the electronic board does not detect the flame. Based on this, it is recommended to check it.

Overheating of the Westen boiler. The device is blocked. The overheating thermostat has switched on – The overheating thermostat, as well as the temperature sensor, are in most cases located on the outlet pipe of the main heat exchanger. The main purpose of the thermostat is to protect the apparatus from unnecessary temperature rise. The malfunction appears due to problems with the thermostat, temperature sensor, and in addition, if there is a malfunction in the main circulation circuit. Temperature sensor failure – The control board receives an incorrect signal or a contact failure between the electronic board and the sensor. Breakdown of the overheating thermostat – If the thermostat is working, but the actual overheating of the liquid has occurred, then there may have been a problem with the circulation of the coolant in the heating circuit.

Means that the pressure inside the system is reduced. The main factors in the occurrence of this problem: a decrease in water pressure in the heating system. There is no contact between the pressure switch and the control board. Defective pressure switch. First of all, you need to check the readings of the pressure gauge. Typically, the failure can be cleared with a make-up tap that is designed to add water to the system. In case the fault repeats, it is likely that there is a fluid leak. The hydraulic pump, primary heat exchanger, relief valve, worn seal elements, make-up valve and other parts can leak. Leakage is determined visually by inspecting hydraulic connections and components.

Poor traction. For stable and safe operation of the Westen boiler, draft must be provided to remove flue gases so that they do not enter the room. This is monitored by automation, and when any problems occur, the draft sensor turns on, and the device is blocked. Possible reasons why there is no draft: small-sized diameter of the chimney channel, incorrect design, blockage, icing of the inner wall. The narrowing of the diameter of the discharge channel causes insufficient traction.
The length of the chimney pipe is exceeded – We advise you to carefully study the operating instructions for the device and check that all necessary requirements are met. A large length of the horizontal section of the flue pipe can lead to a loss of the necessary draft. Traction sensor failure – If a vacuum forms in the inlet tube, a characteristic click can be heard. Poor contact between the pressure switch and the control board, the presence of condensate, as well as incorrect connection of the tubes to the pneumatic switch. Fan malfunction – The fan impeller is clogged. The fan shaft is not lubricated, hence it has low torque. There is no contact between the fan and the board that controls the electronics.
Westen Gas Boiler Error code E06
The hot water temperature sensor is not working correctly. This code means that the DHW temperature sensor has failed or the temperature required for operation has risen. Possible reasons for this problem: the DHW temperature sensor is defective. Lack of contact between the hot water temperature sensor and the electronic board. Damage to the electronic board. If the DHW temperature sensor is working and securely connected to the electronic control board, but at this moment the device shows an error, then the electronic board probably needs repair.

Ignition problem. This circumstance is displayed if the ignition does not work or if a burner flameout is observed. It is required to diagnose the contacts between the ignition unit and the flame electrode, and in addition between the board and the gas valve. The main cause of burner flame separation is insufficient draft.
Westen Gas Boiler Error code E05
The heating circuit temperature sensor is not working correctly. This circumstance indicates a malfunction in the heating temperature sensor or the required temperature has risen. Damage to the heating circuit temperature sensor circuit – This malfunction may occur if the temperature sensor is not communicating with the electronic board, or the temperature is below normal. Five seconds after the fault is detected, the Westen boiler will resume normal operation if the fault occurred by accident. You need to make sure that there is no moisture on the sensor connector and the electronic board connector.
If there is no moisture, the sensor must be replaced. The occurrence of a short circuit of the temperature sensor of the heating system – This problem may occur during a short circuit of the contacts of the temperature sensor or the water temperature is above normal. It is preliminary recommended to measure the resistance of the temperature sensor. If the resistance characteristics do not correspond to the required ones, it is necessary to replace the temperature sensor. If installing a new sensor does not help, change the controller.

The circulation pump is damaged or an air blockage has formed in the heating circuit.
