We send our parts supplier pic of data badge and the part we want on boiler . He sends back pic of part to confirm with price then posts it. Never speak to him bower days unless bored!

Try him he posts next day anywhere in uk and is cheap! If u want number pm. Don't want to upset any sponsors![/QUOTE]

Are they new parts or reconditioned

I'm pretty sure its an old Performa then the one i've been to because its got the old type diverter valve with a microswitch sat over another diaphragm where the dv head is on your pic. Its defo non condensing !!

Am wrong, must be my age catching up with me. Went back last night boiler wouldn't fire at all on DHW or CH, checked all connections back to board for continuity, boiler cycling.... burner lit burner off within seconds.Still no warning lights and still not reaching flame failure, anyway I suspected maybe the gas valve so tapped the top yellow coil and the boiler lit straight away.Tapped it again a few times and the boiler knocked off and back on. So as it was 8.30 last night I've left it running and am thinking of ordering a new coil if possible ??

If it's cycling it's the pcb.

Have you had this before Leo ?? I thought maybe PCB until I touched the gas valve but yep it's lighting on both DHW and CH and immediately dropping then again cycling. Occasionally stays on and remains on.

Yes I've had it before. If you listen it,ll start, run the fan and then when the aps activates it shuts down and repeats. It will fire like this occasionally. Every time I've had it it's been the pcb. Pm gas man he's the top bloke in these, in sure he,ll agree.

agree probably pcb is failing what i have also seen is water leaks cause similar issues runs down the harness and takes out the pcb

Just a quick update, replaced the pcb on monday morning and boiler now all good. Thanks to all
