Termet Gas Boiler Error Codes While combi boilers have a long lifespan and are generally reliable, we can’t forget that they literally work 24/7. After such hard effort, boiler faults are inevitable. Boiler error codes also are not necessarily related to the boiler function as well, but rather to problems like frozen condensate pipe, electrical supply or the flue.
Termet Boiler Error Code Solutions
Termet Boiler Error Code 01
It means that the ignition of the burner is blocked. The flame ionization sensor indicates a malfunction in the apparatus. Such a part recognizes the presence of a flame and suspends the operating cycle of the Termet boiler in case of limited combustion of the main burner or in case of difficulties with the flow of gas. Operation is suspended after 3 unsuccessful launches. To return to work, press and hold the reset key. Gas valve failure – The action of the gas valve is controlled by the electronics board.
This component is tested by measuring voltage and resistance. If the values differ from the standard characteristics, the valve should be replaced with a working one. No gas supply to the machine – There is a valve in the gas distribution system that limits the flow of gas. Based on this, a malfunction at the time of starting the boiler may occur due to a blocked tap. Weak contact or no pulse from the flame control sensor. The electronic board is faulty – If the ignition process was successful, but the device immediately went out, then the electronic board may not detect the flame. Therefore, it should be checked.
Termet Boiler Error Code 02
Problems with overheating of the boiler Termet. The unit stops. The overheating thermostat has tripped – The overheating thermostat, as well as the temperature sensor, are in most cases placed on the outlet pipe of the primary heat exchanger. An important function of the thermostat is to ensure the safety of the device from elevated temperatures. The accident appears due to problems in the thermostat, temperature sensor, and also when the main circulation circuit fails.
The temperature sensor has failed – The electronic board receives an incorrect signal or poor contact between the control board and the sensor. Overheating thermostat failed – If the component is OK, but there was an actual overheating of the liquid, then most likely There is a problem with the circulation of the heating medium in the heating circuit. The main heat exchanger or the heating circuit filter is clogged (lack of circulation means an increased heating temperature of the coolant). Malfunction of the circulation pump or there is an air blockage in the heating system.
Termet Boiler Error Code 08 (09)
Indicates that there is low pressure in the system. The main factors contributing to the appearance of this problem: a decrease in water pressure in the heating system. There is no contact between the control board and the pressure sensor. Defective pressure switch. First you need to know the readings of the manometer. Usually the problem is eliminated with the help of a feed valve, which is mounted to supplement the system with a coolant. In the case when a repetition of the problem is observed, then there may be a coolant leak. A hydraulic pump, a primary heat exchanger, a safety valve for relieving excess pressure, damaged seals and gaskets, a make-up valve and other parts can leak. Leak You can visually identify waterworks and components.
Termet Boiler Error Code 03
There is no traction. In order to ensure stable and reliable operation of the Termet boiler, it is necessary to organize draft to remove exhaust gases so that they do not enter the room. The exhaust of gases is controlled by electronics, and when any malfunctions occur, the draft sensor is triggered and the boiler will stop working. Probable reasons affecting the lack of draft: small size of the smoke duct design flaw, blockage, ice on the inner wall. Reducing the size of the discharge channel serves as a factor in reducing thrust.
The chimney pipe is too long It is recommended that you carefully read the instructions for use of the gas boiler and check that the mandatory requirements are complied with. Too long a horizontal section of the smoke exhaust pipe leads to a weakening of the required draft. Breakage of the pneumatic relay-traction sensor – When a vacuum is created in the inlet tube, a characteristic click can be heard. There is no contact between the electronic board and the draft sensor, there is condensate, as well as improper fastening of the tubes with the pneumatic relay sensor. Fan problems – There is a blockage in the fan impeller. There is no lubrication on the fan shaft, so it does not increase the required speed. There is no contact between the fan and the board that controls the electronics. Accordingly, it does not increase the necessary speed. There is no contact between the fan and the board that controls the electronics. Accordingly, it does not increase the necessary speed. There is no contact between the fan and the board that controls the electronics.
Termet Boiler Error Code 10
Problems with determining the temperature of the DHW sensor. This code means that the DHW circuit temperature sensor is damaged or the operating temperature is exceeded. Main sources preceding this fault: DHW temperature sensor is defective. Poor contact of the control board with the DHW temperature sensor. Damage to the electronic board. If the DHW temperature sensor is OK and connects correctly to the electronic control board, although the device displays an error, then the control board may be damaged.
Termet Boiler Error Code 07
Incorrect ignition. This code is issued if there is no ignition or there is an attenuation of the burner flame. It is necessary to check the connections between the ignition device and the flame electrode, and also between the gas valve and the board. The main cause of burner flame separation is weak draft.
Termet Boiler Error Code 04
The temperature sensor in the heating circuit does not function correctly. This situation indicates that there is damage to the temperature sensor in the heating circuit or the required temperature has been exceeded. Open circuit of the heating water temperature sensor – This problem most often occurs if the connection between the temperature sensor and the electronic board is interrupted, or the temperature is below the nominal value. Within 5 seconds following the detection of a failure, the Thermet boiler must return trouble-free operation, in case the failure occurred accidentally.
It is recommended to make sure that there is no moisture on the temperature sensor connector and the control board connector. If there is no moisture, it is recommended to replace the temperature sensor. There is a short circuit of the heating circuit temperature sensor – This failure occurs due to a short circuit of the temperature sensor contacts or the liquid temperature is higher than recommended. The first step is 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. When installing a new sensor fails, repair the board.
