Central heating not working - Pump and valves work fine

afclucas · 13 Jan 2009

My heating decided to stop working last Friday. I replaced my pump last year so I didn't think it was that, but I check it with the screw driver anyway and it is working fine. I then checked my 2 port zone valve, that wasn't working, so I brought a Drayton 2 port zone valve from B&Q, replace it and wired it as the old one. It didn't seem to work though. I look on the net for further wiring information and eventually found a solution that when I activate CH on my programmer the valve motor works and the pump starts too. But the rads still don't heat up??? I have hot water still but the rads are totally cold, including the feeding pipes either side of the rads.

Any help would be much appreciated.

Thanks
