Hi @gas112 disconnecting the condensate trap wire doesn't make any difference.
The symptoms fit option B the best from the light fault troubleshooting.
Thanks
Hi @ianmcd no difference when holding "reset" for a long time.
Hi @gas112 I still haven't had a chance to check the condensate trap wire - it would fit with the troubleshooting guide
Hi Chris,
Thanks for your reply, the system pressure is good and I suggested a pump issue to the Baxi engineer after looking at the same troubleshooting page as you. He dismissed it as the heating works if there is a call for heat when the boiler is first switched on.
Cheers

Hi
I'm looking for help with strange behaviour from a Main 24 HE Combi Boiler.
Symptoms are when turning the boiler on regardless of either heat & DHW or just DWH are after 5 secs the lights show:
Burner light is off
Flame failure light is flashing slowly
Power on is on
The boiler won't fire...
