  • Fuse replaced at switch we have power to boiler again. F7 error code which is

    F7 Flame detected even though appliance switched off. Check electrode assembly, dry pcb. Flue clear?

    Is it within the realm of diy to get the pcb out and dry it above our dehumidifier then safely refit it? I can isolate the power, obvs.

  • We got the dehumidifier under it & F7 is now C1 (weak fan) so I think I'm out of diy'ing it back to life.
