Boiler will not start up (Potterton Promax HE Plus)?
New boiler installed 10 months ago ( No previous problems ), I have just replaced all my radiators, having drained the system down and refilled and bled all the radiators . I can not get the boiler to run, I have reset the electronis via the re-set button , but still the system will not fire up, any one with any ideas ( I did not touch the boiler, other than switch the system off to drain it down.
