Chaffoteaux Boiler Error Code Solutions
Chaffoteaux Boiler Error Code 501
It means that there is no ignition. The flame ionization sensor signals a malfunction in the boiler. This component detects the presence of a flame and stops the operating cycle of the Shafuto boiler during low combustion of the main gas burner or in case of problems with gas supply. Blocking occurs after 3 unsuccessful starts. To return to work, press and hold the Reset button.
Gas valve failure – The gas valve is controlled by an electronic board. Diagnostics of this element is carried out by determining the values of resistance and voltage. If the readings are found to be out of specification, the valve must be replaced. Lack of gas supply to the system – There is a valve in the gas distribution device that shuts off the flow of gas fuel. As a result, a failure at the start of the boiler may occur due to a closed tap. Incorrect contact or no pulse from the ionization flame sensor. Problems with the control board – If the ignition cycle is performed normally, but the boiler immediately extinguishes, then the control board may not recognize the flame. In this case, you need to test it.

Overheating of the heat exchanger of the Chaffoteaux boiler. The device is blocked. The overheating thermostat has come into action – The overheating thermostat as well as the temperature sensor are mainly located on the outlet pipe of the main heat exchanger. The main task of the thermostat is to protect the device from elevated temperatures. An accident may occur due to problems in the thermostat, temperature sensor, as well as in case of difficulty in the operation of the main circulation circuit.
Temperature sensor problems – The electronic board receives an incorrect signal or a contact failure between the sensor and the electronic board. Overheating thermostat failure – When the sensor is operational, but the actual overheating of the coolant is determined, then there seems to be a problem with the circulation of the coolant in the heating circuit. The primary heat exchanger or the main circuit filter is clogged (insufficient circulation process suggests increased heating of the liquid). The circulation pump is damaged or there is an air blockage in the heating system.
Chaffoteaux Boiler Error Code 108
Is a sign of low pressure in the system. The main factors due to which this malfunction occurs: a decrease in water pressure in the heating circuit. There is no contact between the control board and the minimum pressure switch. The pressure switch is faulty. First, you should 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. If the accident continues, then most likely there is a water leak. The hydraulic pump, primary heat exchanger, safety valve, worn seal elements, make-up valve and other parts can leak. The leak is determined at the time of inspection of the hydraulic components and connections.
Chaffoteaux Boiler Error Code 6P1 (607)
Weak traction. For the stable and safe operation of the Shafuto boiler, it is necessary to provide draft for the removal of combustion products so that they do not enter the living quarters. This is monitored by automation, and in the event of certain problems, the traction sensor-relay will work, and the unit will be blocked. The main reasons due to which a lack of draft is possible: insufficient diameter of the discharge channel, incorrect installation, blockage, ice on the walls. Reducing the size of the outlet channel entails a lack of thrust. Chimney pipe length exceeded It is recommended that you carefully read the operating instructions for the gas appliance and comply with the relevant requirements. Too much horizontal flue pipe can lead to loss of required draft.
Damage to the draft sensor – When a vacuum occurs in the supply tube, a slight click will be noticeable. Disruption of contact between the traction sensor-relay and the electronic board, condensate in the tubes, as well as incorrect fastening of the tubes with the pneumatic relay. Incorrect operation of the fan – There is a blockage in the fan impeller. The fan shaft is not lubricated, therefore it does not develop the required speed. There is no contact between the control board and the fan.
Chaffoteaux Boiler Error Code 201
Failure of the DHW temperature sensor. This situation means that the DHW temperature sensor is damaged or the temperature required for operation has risen. Probable causes of this malfunction: the temperature sensor for hot water supply is defective. Lack of contact between the DHW temperature sensor and the control board. Control board burned out. If the DHW temperature sensor is operational and reliably contacts the electronic control board, but the device displays an error, then, apparently, the electronic board has a defect.
Chaffoteaux Boiler Error Code 5P3 (SP3)
Refusal to ignite. This is displayed if the ignition mechanism does not work or there is a flame break. It is necessary to diagnose the connections between the ignition mechanism and the flame sensor, and also between the gas valve and the board. The main cause of burner flame failure is lack of draft.
Chaffoteaux Boiler Error Code 110 (112)
Failure of the temperature sensor of the heating system. This code indicates a malfunction in the heating temperature sensor or the temperature required for operation has risen. An open in the heating circuit temperature sensor circuit – This problem can occur when the connection between the temperature sensor and the electronics board is broken, or the temperature is below normal. 5 seconds after detecting a malfunction, the Chaffoteaux boiler will restore working functions, in case the malfunction occurred accidentally.
You should make sure that there is no moisture on the temperature sensor connector and the control board connector. If there is no moisture, the temperature sensor must be replaced. There is a short circuit in the temperature sensor in the heating circuit – This failure occurs after a short circuit in the temperature sensor circuit or the temperature of the coolant is higher than recommended. First, it is recommended to measure the resistance of the sensor. If the resistance parameters differ from the standard ones, it is necessary to replace the temperature sensor. When replacing the temperature sensor does not contribute to the result, repair the board.
