I have had problems with my Potterton Suprima 60 which worked well for 7 years but recently it failed and I was advised that the PCB needed to be replaced. This was done by a Corgi engineer but now it works for 3 minutes and then stops for 3 minutes. When it is cold the boiler appears to have difficulty coping although it continues its to operate in its intermittent mode.
What could be wrong.?
Can anyone suggest anything.? The pump was also replaced as well as the zone valve but I believe that the fault lies within the boiler.
