Baxi 105e. Will not ignite.

[ninja1961]

I have just fitted a new diverter to a Baxi 105e boiler. Now the boiler will not ignite. Flame failure neon is flashing. Did not have this problem before I fitted the diverter, only problem with hot water.
Boiler is 8 years old. Help.

Does the fan run and can you hear the boiler sparking?

Are you 100% sure that no water got anywhere near the pcb.

These boards only have to hear water and they go

Thanks for the reply. There was a bit of water spraying around inside the boiler casing. Boiler does not attempt to spark and the fan is running.
Inside the PCB casing appears dry. But it may be that. Cheers

inside usaully looks dry but board can be damp underneath check that.
