Vokera linea

[Terrywookfit]

Fitted for a customer 3 years ago.
Intermittent 01 lockout but always resets first time.
It will sometimes be ok for 3-4 days and then lockout 3 or 4 times in a day!
Every time I go it behaves impeccably!
Checked venturis, electrodes, gas supply and flue !!
I dont want to just start chucking parts at it.
Any one had a similar problem ?

Have you serviced the boiler. By service I don't mean general going over with a duster but a proper service as detailed in the manual

Ignition pcb is the usual suspect.
