Hi Everyone,
Two days ago, when i turned my heating on first thing in the morning, it immediately tripped the mains RCD. I went out to the boiler (its in a little 'outhouse' in the back yard) and flicked the isolator switch, changed the fuse and tried again. Same result.
Starting from the switch, I began to check for any loose or corroded wiring but couldn't find anything obvious. I decided i would check the wiring to the circulating pump (Wilo Gold 50), and when i opened the black case, a small amount of water came out. I tightened the water pipe which had a really slow drip leak that had got into the pump compnent cover.
I dried it all up, and tested the boiler again. It fired up nicely, then cut off after about 30 mins (tripping the mains again). This time without any water involved that i could see. I was able to fire up again immediately and it ran then for about 5 mins before tripping. Now it doesn't do anything when switched on, it doesn't even trip the mains any more.
During the tests, the burner fired up and did a bit of heating. But now it also doesn't start.
My questions is, does the pump in my system control the boiler firing? ie. if the pump is knackered, the boiler wont fire up. Is it safe to test that i have a pump problem by disconnecting it and trying to see if the boiler starts without the pump in the circuit?
I'd like to narrow it right down if possible to obtain the parts before calling out someone to replace the pump.
any help or advice would be greatly appreciated. Boiler is a Reillo 40 if that matters.
thanks in advance!
