Boiler guidance? I have a Baxi 400 combi that is flashing up H.02-0.4 Temporary fault - Parameter error
I have turned it off and on again and repressured, neither of which has helped. There's no ignition sound.
Anything else I can try before I admit defeat and call a plumber?
The other obvious is check that the flue isn't blocked.
Nothing obvious. Thanks!
