Cant find any existing threads so here goes.

This boiler shows no indicator lights whatsoever. Reset button does nothing. Boiler does not make a sound no matter what you ask of it. Checked supply fuse and fuse on ignition sequence board and all ok. Service manual seems to be saying that the ignition sequence PCB is at fault. GC number of boiler is 47-970-28.

Does anyone agree?

I dont think its the ignition board, do you have 230vac at the boiler main supply terminals ?

Many thanks for replies. 230V at the fuse on main board. Fuse is sound. Must be PCB. It came back to life next morning after power was disconnected overnight.

Boiler has 2 boards. One main and one ignition sequencer. Will wait for it to go completely before tackling. Any clues as to which component on the main board it might be? Would have a stab at fixing it if part/s available.
