Hi Guys,
I have a problem with my central heating which I cannot seem to get to the bottom of.
Basically the hot water works just fine, but when I turn on the CH (from cold) roughly 15 mins later the system trips the RCD on the main consumer unit. When I reset it, the CH then trips within a minute or so.
I have tried changing the programmer (Potterton EP2002, I had a spare front panel), and still no luck. The programmer has its own 3A fuse which doesnt blow.
Boiler is a Myson Apollo (looks pretty old but seems to be working fine).
The pump works fine for HW so can't see why that would be a problem? Could it be that the rads are sludged and causing the pump to work hard but only for CH?
No visible leaks around pumps/motor valves.
Please help!!!
