Gazeko Gas Boiler Error Codes Error E6 Indicates a faulty ignition system. Fault notification comes from the flame control sensor. Such a sensor electrode takes into account the presence of a flame and stops the operation of the Gazeco boiler during limited combustion of the main burner device or in case of gas supply problems. The termination of work occurs after three unsuccessful launches.

To resume the workflow, you need to keep the restart button pressed. Gas valve failure – The gas valve is controlled by an electronic board. This element is checked by measuring resistance and voltage. If it is determined that the readings do not correspond to the nominal characteristics, the valve must be replaced with a working one. There is no gas supply to the boiler There is a valve in the gas distribution circuit, which restricts the flow of gas fuel. Consequently, an accident at the time of the start of the apparatus may occur due to a blocked valve.
Poor contact or no signal from the flame control sensor. The control board has a malfunction If the ignition process occurred normally, but the device went out immediately anyway, then the control board may not detect the flame. In this case, it should be checked. the control board does not detect the flame. In this case, it should be checked. the control board does not detect the flame. In this case, it should be checked.
Gazeko Boiler Error Code E4
Overheating of the heat exchanger of the Gazeko boiler. The device is blocked. The overheating safety thermostat has turned on – The overheating thermostat, like the temperature sensor, is most often located on the outlet pipe of the main heat exchanger. The functional task of the thermostat is to ensure the safety of the apparatus from elevated temperatures. Failure can occur due to problems in the thermostat, temperature sensor, as well as malfunctions in the main circulation circuit.
Faulty temperature sensor – The control board receives an incorrect signal or poor contact between the sensor and the control board. Breakdown of the overheating thermostat If the sensor is working, although the actual overheating of the liquid is determined, then it can be assumed that there is a problem with the circulation of the coolant in the main circuit. Clogging of the main heat exchanger or filter element of the heating circuit (weak circulation implies a high heating temperature of the liquid). Malfunction of the circulation pump or there is a blockage from the air in the heating system.

Indicates that the system pressure indicator is low. Probable causes that affect the formation of this problem: a decrease in water pressure in the heating system. Lack of contact between the pressure switch and the control board. Malfunction of the minimum pressure switch. The first step is to check the results of the pressure gauge. In many cases, the failure is corrected with a make-up valve that is designed to add coolant to the system. If the accident repeats, then there is probably a coolant leak. The circulation pump, primary heat exchanger, excess pressure relief valve, damaged seals and gaskets, make-up valve and other components can leak. The leak is determined at the time of inspection of the hydraulic units and components.
Gazeko Boiler Error Code E1
There is no traction. For reliable and safe operation of the Gazeco gas boiler, it is necessary to create a draft for the removal of flue gases so that they do not enter the room. This is followed by automation, and when some problems appear, the draft sensor turns on and the boiler stops working. The main reasons contributing to the lack of draft are: small diameter of the flue duct, incorrect design, clogging, icing of the inner wall. Reducing the diameter of the discharge channel leads to weak draft.
Flue pipes too long We advise you to carefully read the installation manual of the appliance and follow the relevant requirements. The long horizontal section of the flue pipe leads to a weakening of the required draft. Draft sensor failure – If there is a vacuum in the inlet tube, a slight click will be noticeable. There is no contact between the pneumatic switch and the electronic board, the presence of condensate, as well as incorrect connection of the tubes to the pressure switch. Fan stopped – There is a blockage in the fan impeller. The fan shaft is not lubricated, and therefore it does not generate the required speed. Contact failure between the fan and the electronic board.
Gazeko Boiler Error Code E3
Failure of the DHW temperature sensor. This code indicates that there is a malfunction of the DHW temperature sensor or the allowable temperature is too high. Possible reasons why this malfunction appears: the hot water temperature sensor is damaged. There is no contact between the electronic board and the DHW temperature sensor. Control board failure. If the hot water temperature sensor is intact and correctly connected to the electronic control board, but at this moment the boiler displays an error, then most likely the electronic control board is defective.
Gazeko Boiler Error Code E7 (Eb)
Problems at the time of ignition. This code can be issued when the ignition does not work or the flame breaks off. It is necessary to inspect the contacts between the ignition mechanism and the flame sensor, as well as between the board and the gas valve. The main cause of burner flame failure is lack of draft.
Gazeko Boiler Error Code E2
The heating circuit temperature sensor is not functioning properly. This circumstance means that the temperature sensor in the heating system is faulty or the permissible temperature has been exceeded. Damage to the heating circuit temperature sensor circuit – This malfunction can occur if the contact of the temperature sensor with the electronics board is interrupted, or the temperature is below normal.
After five seconds have passed after a malfunction has been recognized, the Gazeko boiler should return to normal operation if the malfunction occurred spontaneously. You should check that there is no moisture on the temperature sensor connector and the controller connector. If there is no moisture, it is recommended to replace the sensor. Short circuit of the temperature sensor of the heating system
This situation occurs during a short circuit of the contacts of the temperature sensor or the liquid temperature is higher than recommended. Initially, you need to measure the resistance of the sensor. If the resistance values do not match the required ones, it is necessary to change the temperature sensor. If installing a working sensor does not help, replace the control board.
