Boiler cut out again, found why the pump was being so tempramental.
The bolt form the center of the propellor on the pump had fallen out. This was not obvious to me when i took the pump out to look at. I only noticed it when i sat it next to a new pump (cp63).
Then started hunting for the...
Cheers for the description on how to test the diverter. Just done it and the diverter is functioning as it should.
Since putting the pump and manifold back on the boiler now fires and stays going so its looking like a dodgy pump. Been running for 20 mins, problem sorted by the looks of it. If...
The sticker on front says potterton combi 80, behind this sticker is another saying puma80/80e. It doesn't have a temperature control on the front and the manual refers to it as a combi 80. I think it is an 80?
The pump bg have finally fitted (after fitting a random one without a gasket that...
Just put back pump and manifold and started up.
Fired up boiler.
1min 15 sec - boiler cuts off (not lockout) pipe for CH initially feels cold as boiler cuts out. then quickly becomes too hot to touch, is this just conduction of heat from hot boiler rather than water flow or is it diverter...
Cheers for rapid responses.
Starting to think Diverter valve is faulty as well.
Would be annoying as I fitted it on thursday from new. When I had it next the old valve I put the ends of both of them in hot water and watched the movement. The new one definitely seemed to move differently...
Took pump out with manifold attached. wired a plug to the side of it and then held manifold in a bucket of water. Pump managed to move water reasonably well. Don't know if there are any other tests I can carry out on pump, it is currently out of the system.
Pump is also fairly new as the...
Havn't checked it with a thermometer, but generally the pipes from the heat exchange feel hot. checked the resistance of central heating sensor and dhw sensor and are within range specified.
Boiler will fire up again quickly if I de-pressurise the system and then re-pressurise. I assume this...
Have now spent a few days trying to get my potterton80 to work on CH.
DHW seems to work ok, but can be a little slow.
Had a problem with boiler locking out after using DHW but cleaned the flow switch assembaly and now the boiler recognises when HW is not being demanded.
When the boiler...
