Hi,
Having a small issue with my Potterton Performa 28I combi boiler. The problem was when the heating was on and you turned on the hot water the boiler switched over to hot water then when the tap was switched off it did not revert beck to heating.
After 6 visits from the Gas Board they finally found a sticking diaphragm, they managed to soak the main PCB switched the system on and blew it up! The PCB was replaced and finally everything is working as it should.
The problem I now have is, I dont think that the hot water is as hot as it used to be. The temerature leds on the panel light up as the water heats but the water does not feel as hot as the leds say. Is there any adjustments that need to be carried out on the PCB relating to adjustable resistance pots that aligns the temp leds to the actual temp of the hot water as the Gas board engineer just fitted the board without any adjustments.
Thanks,
Dennis
