Hi Tony, thanks for your comments...
Yes I am thank you. I do carry some spares (like the fan and pressure switch we have already changed) but with 40-odd boilers of all makes and models under the sun it isn't possible to carry everything.
Well we'd discounted an electrical problem because...
Thanks for that, can you explain what you mean? I've completely removed the board and resoldered it. The PCB has two relays on the board. I have swapped them around in case one was faulty, but the fault's still the same. It doesn't prove the PCB's not faulty though.
I'll check the flue more...
Hi All,
Please can someone shed some light on this problem...
Firstly I'm not Corgi registered myself, I'm a professional landlord and one of my tenants boilers has failed. I've been working with my gas man to get this boiler fixed but we're both stumped!
We have a Potterton Prima 30F...
