What causes a Baxi COMBI 224 Boiler to display 'Flow temperature sensor short-circuited'?
If your Baxi Boiler displays 'Flow temperature sensor short-circuited', it could be due to: * Sensor not or badly connected: Check the wiring. * Bad connection: Check that the sensors are operating correctly. * Sensor fault: Check that the sensor has been correctly fitted and replace the sensor if necessary.
What causes a Baxi COMBI 224 Boiler to display 'Return temperature sensor short-circuit'?
If your Baxi Boiler displays 'Return temperature sensor short-circuit', it could be due to: * Sensor not or badly connected: Check the wiring. * Bad connection: Check that the sensors are operating correctly. * Sensor fault: Check that the sensor has been correctly fitted and replace the sensor if necessary.
What causes a Baxi COMBI 224 Boiler to display 'Return temperature sensor open-circuit'?
If your Baxi Boiler displays 'Return temperature sensor open-circuit', it could be due to: * Sensor not or badly connected: Check the wiring. * Bad connection: Check that the sensors are operating correctly. * Sensor fault: Check that the sensor has been correctly fitted and replace the sensor if necessary.
What should I do if my Baxi Boiler displays a 'False flame signal'?
If your Baxi Boiler displays a false flame signal, it could be due to: * Short-term fluctuation of the mains: Press the RESET button for 5 seconds. * Ionization current present even though there is no flame: Replace the ionization/ignition electrode. * Sensor fault: Set the CO2. * Defective gas/air unit: Check the gas/air unit and replace if necessary.
What to do if my Baxi Boiler is not working?
If your Baxi Boiler isn't working, first check that the boiler is being supplied with power by checking the fuses and switches. Ensure that timers and thermostats are calling for heat. If the water pressure is too low (less than 0.5 bar), re-pressurise the system. Check that the gas isolation cock is fully open to ensure adequate gas pressure. Also, press the Reset button, and correct any error if possible. Finally, inspect the condensate drain for blockages, especially in external runs during freezing temperatures.
What causes a Baxi COMBI 224 Boiler to have a communication error with the NTC flue sensor?
If your Baxi Boiler shows a communication error with the NTC flue sensor, it might be due to the sensor not being connected properly, so check wiring. Another cause may be bad connection, so check sensors are operating correctly. Also, check that the sensor has been correctly fitted. If necessary, replace the sensor.
What to do if my Baxi COMBI 224's maximum flue gas temperature is reached (> 140 Deg C)?
If the maximum flue gas temperature is reached in your Baxi Boiler, it could be due to: * No circulation: Vent the air in the heating system. * Sensor fault: Check the water pressure, check the wiring, check the circulation (direction, pump, valves), check the cleanliness of the heat exchanger, check that the sensors are operating correctly and replace the sensor if necessary.
What to do if my Baxi COMBI 224 Boiler has no circulation?
If your Baxi Boiler has no circulation, it could be due to: * No circulation: Vent the air in the heating system. * Sensor not or badly connected: Check the water pressure and check the wiring. * Sensor fault: Check the circulation (direction, pump, valves), check the cleanliness of the heat exchanger, check that the sensors are operating correctly and replace the sensor if necessary.
Why is my Baxi COMBI 224 Boiler showing a 'Gas Valve fault'?
If your Baxi Boiler indicates a gas valve fault, the gas valve may not be detected. Check the wiring. Also, check the resistance across gas valve terminals. If necessary, replace gas valve.
How to fix no circulation of water in my Baxi COMBI 224 Boiler?
If there is no circulation of water in your Baxi Boiler, it may be due to: * Non-existent or insufficient circulation: Check circulation. * Sensor error: Check water pressure, check sensors are operating correctly, check that the sensor has been correctly fitted, check the cleanliness of the heat exchanger and check pump.
