Any help on the following would be much appreciated!!
When i turn on the hot water tap the boiler fires up and operates normally, however when i turn of the tap the boiler continues to run and the only way to stop it is to turn of the power!!
Is this due to a faulty PCB or something else??
the pressure does rise when the hot water is on but not significantly. I've just been outside and looked at the pressure release pipe and there is some water there??
I have a potterton puma 80 boiler and recently it has started to lose pressure. I can top it up from the inlet but obviously there is something wrong!! I have chacked all the rads and valves + pipework under the floor for leeks in the system and found nothing!! The boiler is currently lossing...
