Olical Gas Boiler Error Codes Even boilers have their bad days. Many different kinds of faults can develop with your boiler. Certain boiler problems lead the boiler to go into a safety lock-out mode after which fault code information is generated on the display. With proper Ideal boiler troubleshooting, you can identify different boiler fault codes and find an adequate solution.
Olical Gas Boiler Error Code Solutions
Olical Boiler Error Code E1
Indicates the absence of ignition. The ionization flame sensor signals a failure in the boiler. This component takes into account the presence of a flame and suspends the operation of the Olikal boiler during incomplete combustion of the main gas burner device or when gas is interrupted. Blocking occurs upon completion of 3 unsuccessful launches. To restore the functions, it is necessary to hold down the R key. Gas valve malfunction – The operation of the gas valve is controlled by an electronic board.
Diagnostics of this element is performed by determining the value of resistance and voltage. If it turns out that the values do not correspond to the nominal characteristics, it is necessary to replace the valve with a working one. No gas flow to the unit – There is a valve in the gas distribution device, which limits the flow of gas. Based on this, a malfunction when starting the boiler may occur due to a closed tap. Poor contact or no pulse from the flame ionization sensor. Problems with the control board – When the ignition process is carried out correctly, but the unit still suddenly goes out, it seems that the electronic board cannot detect the flame. Based on this, it is necessary to check it.
Olical Boiler Error Code E2
Problem with overheating of the Olical boiler heat exchanger. The device is blocked. The overheating protection thermostat has come into action – The temperature sensor and the overheating thermostat are mainly installed on the outlet pipe of the primary heat exchanger. An important function of the thermostat is to ensure the safety of the apparatus from high temperatures. The accident most often occurs due to problems with the thermostat, temperature sensor, and in addition, if the main circulation circuit fails.
The temperature sensor is out of order – An incorrect signal is received on the electronic board or a contact is broken between the control board and the sensor. Faulty overheating thermostat – When it is in good condition, but a real overheating of the coolant is detected, then it seems that there has been a violation of the circulation of the coolant of the main circuit. There is a blockage in the primary heat exchanger or the filter element of the main circuit (insufficient circulation process causes a high heating temperature of the coolant). There is a problem with the circulation pump or there is an air lock in the heating system.
Olical Boiler Error Code E4
Means that the pressure inside the system is reduced. Probable causes that affect the formation of this problem: a decrease in fluid pressure in the heating system. Lack of contact between the pressure switch and the control board. Pressostat malfunction. First, be sure to check the pressure gauge. In many cases, the problem can be eliminated with the help of a make-up valve, which is installed to fill the heating system with coolant. When the failure occurs again, it appears to be a fluid leak. The hydraulic pump, main heat exchanger, excess pressure relief valve, worn gaskets, make-up valve and other components can leak. Leakage can be found by inspecting hydraulic connections and components.
Olical Boiler Error Code E3
No traction. For the reliable and safe operation of the Olical gas boiler, it is recommended to provide a draft for the removal of combustion products so that they do not enter the living quarters. The exhaust of gases is controlled by electronics, and in the event of certain problems, the draft sensor will work and the boiler will be turned off. The main sources of lack of traction: insufficient diameter of the discharge channel, incorrect design, clogging with dirt, ice on the inner wall. Reducing the diameter of the chimney can cause a lack of draft. The flue pipes are too long It is recommended that you carefully read the instructions for use of the gas appliance and check that the mandatory requirements are complied with. A very long horizontal outlet of the chimney pipe can be a source of lack of draft.
The pressure switch-draft sensor is broken – When a vacuum is created in the inlet tube, a soft click will be heard. The contact between the traction sensor relay and the electronic board was broken, condensate in the tubes, as well as incorrect connection of the tubes to the pneumatic relay. Fan stopped – The fan impeller is clogged. There is not enough lubricant on the fan shaft, and therefore it cannot develop the required speed. Contact failure between the fan and the board that controls the electronics. There is not enough lubricant on the fan shaft, and therefore it cannot develop the required speed. Contact failure between the fan and the board that controls the electronics. There is not enough lubricant on the fan shaft, and therefore it cannot develop the required speed. Contact failure between the fan and the board that controls the electronics.
Olical Boiler Error Code E6
Problems with determining the temperature of the DHW sensor. This code means that the DHW temperature sensor has failed or the required temperature has been exceeded. Probable causes affecting the formation of this malfunction: the temperature sensor for hot water supply is damaged. Poor contact between the electronic board and the DHW temperature sensor. The control board has failed. If the hot water temperature sensor is operational and is in stable contact with the control board, although at this moment the device displays an error, then, apparently, the control board needs to be repaired.
Olical Boiler Error Code E5
Ignition problem. This circumstance occurs if the ignition mechanism does not work or there is a burner flameout. It is necessary to check the contacts between the ignition mechanism and the flame sensor, and also between the gas valve and the board. One of the factors in the extinction of the flame of the burner may be unsatisfactory draft.
Olical Boiler Error Code E7
The temperature sensor of the heating circuit is not working correctly. This code indicates a malfunction in the heating temperature sensor or the recommended temperature has risen. The heating system temperature sensor circuit is damaged – This malfunction may occur if the connection of the temperature sensor to the control board is broken, or the temperature reading is below the nominal value. Within 5 seconds after recognizing a malfunction, the Olikal boiler must restore its usual operation if the malfunction occurred by accident.
It is necessary to make sure that there is no moisture on the sensor connector and the controller connector. If there is no moisture, you need to change the temperature sensor. There is a short circuit in the heating water temperature sensor – This failure may occur when there is a short circuit in the temperature sensor circuit or the temperature value of the coolant is above normal. Initially, you need to measure the resistance of the sensor. If the resistance characteristics differ from the standard, it is necessary to change the sensor. When replacing the temperature sensor does not work, change the controller.
