Glow-worm 100 ff

[Darkcloud]

I went to a fault on a glow worm and a relay on the board is chattering like the clappers and the fans starting then stopping (2-3 secs) and the burner actually lights then goes out, must be a sensitive aps. Vaillant tech is closed for the weekend. Any ideas, I suspect the pcb.

Thanks DC

Worth checking the microswitch resistance but sounds like a dry joint on the pcb 🙂 1st thoughts 🙂

I'll post when resolved

Thank you DC
