Hi my boiler was flashing L7 and L8 replaced the flow switch which stopped the leak but now it is stuck on 00 and nothing I do starts the boiler up. No leaks on radiators have tried reset and all other options in book supplied would appreciate any other suggestions. Many Thanks Lynne

Do you have an intellistat fitted? If so, ensure the boiler hasn't "forgotten" about it. On mine, if the intellistat is there but switched off in the boiler setup, it won't do CH, only DHW.

It managed to forget about the intellistat after a recent extended power failure. Enabling it in the config sorted it.
