Can anyone help please! I have spent all day diagnosing why my heating doesn't come on. Turn up room stat until it clicks- yep Look at boiler- led comes on for power to boiler- yep - so I know that room stat and external controls all ok. Downloaded ideal fault finder flow diagram and...

Plumbers not interested so did it myself. Didn't have to disturb servo/gas so job done, happy days, valve has twice as much lift= loads of hot water , cuts in at lower pressure, and switches between water and ch properly! Wife had 30 min shower- just because she could! I had drama with ch...

Thanks mate your a legend

Ok guys one last bit of advice if you can help. Just got the new valve but awaiting plumber. I have ordered the right valve 011299 but it's slightly different. On my original valve there is a small copper pipe coming off the right hand side just above a water connection. This pipe goes to a...

I'll order the support too. I'm glad you both agree! Thanks again.

Ok I'm understanding a bit more now. The temp dial seized many moons ago in what looks like the max hot position so I'll get a whole new valve as opposed to just replacing the diaphragm. Would the valve come with the cam/ pushrod or is this separate ? Cheers

Thanks guys, I re- adjusted last night. Heating fine and shower better but not brilliant. I'll order the other valve but at least it's ok for now. I am confused but I am learning! Thanks again I'll keep you posted. F

Spring Is there ( fiddly to fit) and I'm awaiting part and plumber. In the mean time I'll re- adjust- it it because it cant pull down to the required level? Thanks for your help, it's -2 outside so I'm not popular with wife- guess she could go have a hot shower!

Wonderful long hot shower this morning.... But the heating didn't cut in! Pump runs but burner didn't fire. Have I reduced the water pressure coming in too much or over adjusted diverted valve? Any ideas guys? Thanks

The locking fault is whats called cycling. When a motor fails or gets old and lazy it causes this. All the motors fire together but the lazy one is still only half way when the others have finished. This means that the others think the are unlocking and not locking - hence it opens again. Sit in...

I've been doing a bit more diagnosis and it was looking like the valve you mentioned. I was reading about how flow rate will affect heat so checked mine - 20 litres in 60 seconds. I reduced this to 14 litres but this meant that the plunger on top of that valve was not acting on the hw...

Heat exchanger is the newer type and if i grab the outlet from it with taps on it can get really hot. Also flow is fine so should this unit be ok? I don't understand how sometimes it can be really hot for ages but then it can be ok for a minute then goes cold. Or it can run a whole bath with...

My plumber is a git! It happens worst on shower mixer but also bath mixer and normal taps so i think it is boiler. I've got the heating on now and if i turn tap on slow it is really hot - does this mean that diverter is ok? When i go higher flow temp decreases. Is the diverter the valve with the...

Hi, I have a combicompact VCW GB 242 EH and the old girls got issues...The radiator temperature is fantastic but the hot water isn't. It started several months ago with the hot water getting less hot. After a while we were having to reduce flow at the taps ( flow rate is perfect ) to get the...
