What to do if my Baxi COMBI 228 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.
What to do if my Baxi COMBI 228 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.
How to fix no circulation of water in my Baxi COMBI 228 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.
What should I do if my Baxi COMBI 228 shows a communication error between the gas valve and PCB?
If your Baxi Boiler displays a communication error between the gas valve and PCB, it could be due to a fault in the air/gas unit, in this case, replace the air gas unit. Alternatively, there might be a loose connection to the gas valve, so check the gas valve connection from the PCB.
What should I do if the CH Flow temperature is increasing too fast in my Baxi COMBI 228?
If the CH Flow temperature is increasing too fast in your Baxi Boiler, it could 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 and check the cleanliness of the heat exchanger.
How to resolve a Baxi COMBI 228 Boiler's incorrect fan speed?
If your Baxi Boiler's fan speed is incorrect, it could be due to an external draught over the boiler, so check for adequate draw on the chimney connection. It may also be caused by a defective gas/air unit, so check the gas/air unit and replace it if necessary.
What causes 5 x flame loss in 24 hours with burner on in Baxi COMBI 228?
If your Baxi Boiler experiences 5 flame losses in 24 hours while the burner is on, possible causes include: * No ionization current: Purge the gas supply to remove air. * Sensor fault: Check that the gas valve is fully opened, check the supply pressure, check the operation and setting of the gas valve unit, check that the air inlet and flue gas discharge flues are not blocked and check that there is no recirculation of flue gases.
What causes no flame during operation in a Baxi COMBI 228?
If there is no flame during operation in your Baxi Boiler, it could be due to several reasons: * No ionization current: Purge the gas supply to remove air. * Sensor fault: Check the gas valve is fully opened, check the supply pressure, check the operation and setting of the gas valve unit, check the air inlet and flue gas discharge flues are not blocked, check that there is no recirculation of flue gases.
Why are my radiators cold with my Baxi Boiler?
If your radiators are cold when using your Baxi Boiler, first, check the temperature set point for the heating and increase it using the CH temperature knob or your room thermostat. Make sure the heating mode is activated. Ensure that all radiator valves are open. Also, check that the boiler is receiving power by checking the fuses and switches, and verify the gas isolation cock is open. If the water pressure is too low (below 0.5 bar), re-pressurise the system.
How to fix no domestic hot water in my Baxi COMBI 228 Boiler?
If your Baxi Boiler isn't providing domestic hot water, start by ensuring the boiler is receiving power by checking the fuses and switches. Also, verify that the gas isolation cock is fully open and, if applicable, that your prepayment meter has sufficient credit. It's also possible that the DHW function is switched off, so try activating the DHW mode. Check the water pressure; if it's below 0.5 bar, re-pressurise the system. Finally, make sure the flow is at least 2.5 litres per minute.
