baxi instant

[REDSAW]

105e, turn on, pump runs, h/w light illuminates (no taps open) fan twitches. h/w and 50 (fan) neons flash=nothing.

changed all sensors or jumped them, aps, venturi clear and div motor swapped out. i got it fired up twice in an hour and that was it (when i swapped the div valve over). no 240v to fan at sequence.

upon reset if the h/w dial is in the off position, it does not trigger fault but boiler still dosnt work!

put down to pcb. any coments?:stuart:

possibly as there is a leak at pump valve vent and condensation/pipes wet on blow-off!.
checked pcb for damp but looked ok.

dont have a test board anymore, so decided not to run a £180 gamble as i ran out of ideas and told him to call baxi!!!!!!
