Yeah, the valves are open. :)

Hi guys, I've managed to replace the old pump with a new one that works but now have an issue with our boiler cutting out after a few mins and not starting up again. I had to replace the valves which involved a partial drain as suggested so could this be some form of air lock in the...

Ah OK a partial drain doesn't sound as bad. If I have to resort to any draining at all, when I come to refill the system would I need to add any chemicals or anything? I understand that the system should contain an 'inhibitor' so when drained, either in part or full, would this need...

I'll give a bit of WD40 a try to see if that helps first. :) FYI I believe our CH system is an open vented one with a tank in the loft, cylinder motorised valve, and pump in an airing cupboard and the thermostat, programmer and boiler downstairs. Using some kind of pipe freeze sounds like...

Thanks for the reply kevplumb, It's looking more likely I will replace the pump now. If I replace the pump is there anything I need to look for in particular with a new pump or are they fairly standard with regards to size, connection, etc? Also I have had a go at closing and opening the...

Hi guys, Our central heating has stopped working recently and after a little investigation I believe this to be an issue with the pump but I am not sure if it is just blocked in some way and can be corrected in situ, or whether it needs replacing. The pump is Wilo Gold about ten-fifteen...

Just wanted to say thanks for the replies - it was the motor after testing which was duly replaced and now we have central heating again!!! The wife is now very happy! :) Many thanks again for the responses! Dibely

After testing the wires in the valve I get the following: CH only on at programmer: 240V on the white wire 0V on the orange wire Can't test the grey one as it is too difficult to get to I think from this the request for heat is coming through to the valve but the motor doesn't start so...

Thanks for the quick replies!! OK I will go dig out a multimeter to test the motor. :)

Hi, Our central heating has stopped working recently (it was OK last week although it was probably the first CH use for some time) and I am trying to find the cause. When I switch the central heating on at the programmer it doesn't trigger the boiler to fire up at all or for any water to...
