Hello
Can anynoe help check my diagnosis of a boiler fault? It's a Potterton Performa 28i combi. The hot water is fine, but nothing flows around the heating circuit.
I've proved that the pump is running ok, by keeping the divertor pin plunged until the rads get hot.
I've proved that there is power going to the clock, but it seems to have a very high resistance (around 18 Ohms) when the switch is closed.
If it's not the clock switch then I think it must be the PCB.
Is this a commonplace type of fault? If so, what's the most frequent cause?
