Saunier duval Xeon 60ff fault

[Andyh]

hiya fellas , ( I'm GSR but don't have the blue icon yet after my username ^)
I attended a breakdown last night on said boiler
The voltage through the aps and fan was spiking and the fan would run for a second then cut out .....continuously...
Rang helpline but ( glow worm/ valliant) don't look after these crap now ....
He did suggest the aps though but I'm not 100% sure as the voltage comes from the board surely...?
Any one had this problem ? Any help would be great
Cheers

if you mean hunting then its the board this is basically a badged glow worm ultimate isnt it

Could be right I'll check the mi on both boilers and compare ..
Not sure but fan runs for a second then voltage disappears and it repeats process..
As ever I don't like swapping boards without their tech help confirmation...
looks like I'm gonna bite the bullet and get board ..

I would say the aps is just a switch so if tested out OK and the fan runs when the voltage present then the issue is surely before this.
