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.

somehow I thought you'd said it was sending hot water to the radiators unexpectedly? Is that when hot tap was turned on?

It seemed to have. Maybe the wet sent the wiring bonkers and had it running before the fuse blew, I was in a different room so not sure what went on. Edit: We weren't running taps either, partner was chatting with a friend and heard the fuse pop.
