OK, thanks guys.
Will get the brother in law over with his kit as he has a bit more knowledge than me. Plus if it is the valve, think he has a spare.
Cheers for the advise, will let you know how I get on.
There is a three-way valve, which appears to be operating fine. It sits in one position for the hot water, and when the CH is turned on it moves position. However, nothing else happens.
Hi all
I know this question has probably come up before, but I've searched through things & still at square one.
We've got an old Ideal W2000 boiler & apart from a couple of small issues it's been OK. A few days ago the boiler fired up for the central heating, only to cut out 30secs later...
The Honeywell controller does seem a little dodgy upon further inspection. Kind of flickers between things/settings.
Sounds like I need to ring someone in the morning to take a look, diagnose/fix the issue & flush out the system.
