I got Sime Friendly Format 80E boiler which keeps blowing main PCB fuses and the pump.
Few weeks ago the pump gave up the ghost and it looked like a simple fix so the plumber replaced the pump. The fuse on the main PCB was also blown which I thought was the result of the pump shortening out.
Then a couple of weeks later the same thing happened again. The plumber assumed that it was some faulty batch so decided to use a different brand of the pump.
It was working fine for a couple of weeks and tonight it blew the fuse again.
Not sure if the pump is gone again but I would think that the problem was not with the pump itself from the very beginning and something else needs sorting out.
I can't see any leaks anywhere. The board seems to be dry. If I disconnect the pump and open the tap or switch central heating on then the boiler fires up but obviously the water does not circulate in the radiators.
What could be the problem? Is it the PCB, pump (hard to believe that it would be the 3rd faulty pump) or the wiring? How can I check if the pump is still working?
I have a multimeter, can check various things and understand a lot of these things but really need your help here.
