Potterton suprima 60 boiler fault

[SPH]

Hi, to me it sounds like a circulation problem, i would check the system for air, bleed the rads and check that the header tank in the loft has water in it about 1/4 full (the small tank) there is a common fault with these boilers PCB if you have a round rest button and a round grey temp control knob on the boiler then you have the old style PCB, they are fairly easy to fit but do cost abit to buy approx £200.00 +

sounds like faulty thermistor

have you considered checking the flow and return temperatures for the boiler. if the differential is correct then it is not a flow problem. then you can assume PCB problem or the dry pocket thermistor which is rubbish and fails.

Hi All,

It was the PCB had dry joints all over it. Had it replaced and now everthing is fine.

Many thanks for all the replies.

Hi, I have a Potterton Suprima boiler at my flat with underfloor heating. Few months back, my circulating pump burnt out. The plumber replaced the pump and the flow switch. But after that intermittently my boiler light turns red. every few days. if i press reset it works. Now I would say it is happening more frequently, once every few days. Can you guys please help what could be the problem ? From what I hear it could be PCB. I will change it but want to be sure if thats the only problem.
Anyway I can diagnose the problem myself before calling someone?

Thanks

Ah the infamous Potterton heap!

The Suprima have caused Potterton to become a bit of an "in" joke in the trade.

Hi iamanshul you need to think about replaceing this boiler, PCB £200.00 + but if you can diagnose the fault yourself why are you asking on here ??
