What to do if my Baxi Boiler has ignition failure?
If your Baxi Boiler fails to ignite after 5 attempts, ensure the gas valve is open and there's no air in the gas supply. Verify the gas supply pressure and check the wiring for the flame sensing electrode and ignition switch, ensuring they are intact and properly connected. Also, verify the correct operation of the condensate drainage.
How to resolve a fault in system filling phase for my Baxi DUO-TEC COMPACT+?
To resolve a fault during the filling phase of your Baxi Boiler, check the filling tap.
What should I do if my Baxi DUO-TEC COMPACT+ shows a communication problem between the boiler board and control unit?
If your Baxi Boiler shows a communication problem between the boiler board and control unit, check the wiring between the Ambient Unit and the electronic board or RF link.
What does it mean if my Baxi DUO-TEC COMPACT+ Boiler displays 'Hydraulic circuit automatic filling in progress'?
If your Baxi Boiler displays 'Hydraulic circuit automatic filling in progress', simply wait for the filling cycle to complete.
What to do if my Baxi DUO-TEC COMPACT+ Boiler has a gas valve connection error?
If your Baxi Boiler shows a gas valve connection error, check the connections between the gas valve and the electronic board.
What to do if my Baxi DUO-TEC COMPACT+ Boiler shows a gas valve control error?
If your Baxi Boiler displays a gas valve control error, check the connections between the gas valve and the electronic board. If the issue persists, you may need to replace the electronic board.
How to troubleshoot a Baxi DUO-TEC COMPACT+ fan fault?
To troubleshoot a fan fault in your Baxi Boiler, verify the fan is operating correctly. Also, check that the fan power supply wiring is connected to the electronic board.
What to do if the safety thermostat tripped due to overtemperature in my Baxi DUO-TEC COMPACT+ Boiler?
If the safety thermostat in your Baxi Boiler has tripped due to overtemperature, check the pump operation by unscrewing the front cap and releasing the pump impeller with a screwdriver. Verify the pump power input wiring. Inspect the limit thermostat for damage and replace if necessary. Also, check the continuity of the limit thermostat wiring.
What causes a Baxi Boiler to lose flame at ignition?
Loss of flame at ignition in your Baxi Boiler can be caused by a faulty or incorrectly positioned flame sensing electrode. Check that the electrode is in good condition and correctly positioned. Ensure the wire is uninterrupted and makes good contact with the flame sensing electrode and the ignition switch. Also, check for any recirculation of fumes.
What to do if my Baxi DUO-TEC COMPACT+ has no flame?
If your Baxi Boiler has no flame, check that the flame sensing electrode is in good condition and correctly positioned. Also, check the wire is uninterrupted and makes good contact with the flame sensing electrode and the ignition switch.
