Potterton suprema pilot light woes

skatewing

Well,after sorting out one problem,thanks to all your help my boiler now has another problem...

each time i tray to use the boiler the pilot light tries to ignite then immediatly trips the rcd...so now i cannot even turn it on at all....

No hot water/heating/nothing....

Any ideas

this points to one of Kev's diagnosis - RGI job

Off Ebay......probably why it has gone so quickly. You find that cutting corners rarely saves money

Tell me about it.....

At first it was mv on 2 port valve tripping rcd...new pcb fitted now that doing it....

I have just read that theres a modified board out there would it be worth just buying one of those??

sounds like gas valve solonoid fualty,
old boards two led at front are flawed.
upgraded pcb has single led,wire loom,front fascia,and pcb incased in plastic box.
u need rgi again
