Elsoterm Boiler Error Code Solutions
Elsoterm Boiler Error Code 01 (E1)
It indicates a malfunction in the ignition system. Fault notification comes from the flame control sensor. This sensor-electrode detects the presence of a flame and blocks the operation of the Elsotherm boiler in case of insufficient combustion of the main burner or in case of problems with gas supply. Termination of work occurs after three unsatisfactory starts. To get it working, you need to keep the reset button pressed. Gas valve failure – The gas valve is controlled by an electronic board.
Diagnostics of this part is performed by determining the value of resistance and voltage. If it is found that the values differ from the standard parameters, it is recommended to replace the valve. Lack of gas inflow to the device – A valve is installed in the gas distribution circuit that shuts off the supply of gas fuel. Consequently, a malfunction at the time of switching on the device may appear due to a blocked tap. Poor contact or no signal detected from the flame control sensor. Faulty control board – When the ignition cycle is successful, but the device immediately died out, it is possible that the electronics do not recognize the flame. Based on this, you need to check it.
Elsoterm Boiler Error Code 04 (F5)
The heat exchanger of the Elsotherm boiler is overheated. The unit stops. The overheating thermostat is activated – The temperature sensor and the overheating thermostat 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 excessive temperature rise. An accident can occur due to problems with the thermostat, temperature sensor, and also in case of malfunctions of the main circulation circuit.
Temperature sensor problems – The control board receives an incorrect signal or a contact failure between the sensor and the control board. Faulty overheating thermostat – When the thermostat is operational, but a real overheating of the liquid is detected, there may be a problem with the circulation of the heating medium in the heating circuit. Clogging of the main heat exchanger or filter element of the heating circuit (lack of circulation indicates an increased heating temperature of the coolant). A malfunction with the circulation pump or an air blockage has occurred in the heating system.
Elsoterm Boiler Error Code 95 (F2)
Speaks of insufficient pressure inside the system. Probable causes influencing the formation of this malfunction: reduced water pressure in the heating circuit. Poor contact between the electronic board and the pressure switch. Malfunction of the minimum pressure switch. The first step is to check the readings of the manometer. In many cases, the problem can be eliminated by using a make-up valve that is designed to add fluid to the system. If the fault repeats, then most likely there is a coolant leak. The circulation pump, main heat exchanger, relief valve, worn seal elements, make-up valve and other components can leak. The leak is determined visually when inspecting hydraulic assemblies and components.
Elsoterm Boiler Error Code 07 (F1)
No traction. For the correct and safe operation of the Elsotherm boiler, it is necessary to create a draft for the removal of combustion products so that they do not enter the living quarters. This is monitored by automation, and when any problems occur, the draft sensor will turn on and the unit will stop working. The main reasons preceding the lack of draft: small-sized diameter of the chimney channel, incorrect design, clogging, ice on the inner wall. Limiting the diameter of the flue duct can cause a weakening of the draft.
Exceeding the maximum length of the chimney We advise you to carefully read the installation instructions for the gas appliance and comply with the relevant requirements. A sufficiently long horizontal section of the flue pipe leads to a weakening of the required draft. Traction sensor failure – If a vacuum is formed in the inlet tube, a soft click will be heard. There is no contact between the pneumatic relay sensor and the electronic board, the presence of condensate, as well as incorrect connection of the tubes to the pneumatic relay.
Fan problems – There is a blockage in the fan impeller. The lack of sufficient lubrication of the fan shaft, so it cannot develop the required speed. There is no contact between the electronic board and the fan. therefore, he cannot develop the necessary speed.
Elsoterm Boiler Error Code 14 (F4)
The temperature sensor for hot water does not work correctly. This code indicates that the DHW temperature sensor is faulty or the allowable temperature has risen. The main sources preceding this malfunction: the temperature sensor for hot water supply is damaged. There is no contact between the control board and the DHW temperature sensor. Control board burned out. If the DHW temperature sensor is operational and firmly in contact with the control board, but at this moment the device displays an error, then the control board probably needs to be replaced.
Elsoterm Boiler Error Code 02 (E2)
Ignition problems. This situation may occur when there is no ignition or a burner flameout occurs. It is necessary to check the contacts between the ignition device and the flame electrode, and also between the electronic board and the gas valve. The main cause of burner flame separation may be a lack of draft.
Elsoterm Boiler Error Code 24 (F3)
Malfunction of the temperature sensor of the heating system. This code reports a malfunction of the temperature sensor in the heating system or the required temperature has been exceeded. Damaged heating system temperature sensor circuit – This problem occurs when the connection between the temperature sensor and the control board is broken, or the temperature is below the recommended value. After 5 seconds, following the detection of a malfunction, the Elsotherm boiler should resume normal operation, in case the malfunction occurred accidentally.
It is recommended to check that there is no moisture on the temperature sensor connector and the control board connector. If there is no moisture, the temperature sensor needs to be replaced. The occurrence of a short circuit of the temperature sensor in the heating circuit This situation occurs when the contacts of the temperature sensor are short-circuited or the temperature of the liquid is above normal. First of all, it is required to measure the resistance of the temperature sensor. If the resistance parameters do not match the required ones, it is recommended to replace the temperature sensor. If the installation of a working sensor does not contribute to the result, replace the control board.
