Baxi 105e

[mast9799]

Hi, I have a fault with my 105e. No CH or DHW, when I checked the boiler the flame failure warning light was flashing. I reset the boiler and it sounded like it was about to fire up when it made a fizzing sound and the power light went off. When I opened it up the internal fuse had blown and there was a distinct burning smell from the back of the board.Does this ring any bells, can anybody help?

Sounds like you need a new PCB

Before you fit a new board look at why it went fizzzzz.Usual suspects pump,fan etc.Check there resistances for short circuit
