Wow! This takes me back! My solution was to move house... (no, seriously, I have moved since all this!). In the end, I got the professionals in. Called a plumber in who replaced the whole valve. Sorted it. Wasn't something I felt I could take on myself.

Ok - done. Took motor off, unlocked lever, jiggled back/forth for good measure and then let it sit in the HW postion. Refitted motor and turned CH on. Nothing from the boiler and the valve doesn't move. Lever stuck pretty firm. (thanks for all your help on this!).

Ok, cool. Wiggled back and forth quite a number of times and then locked it in manual/mid and refitted motor. Put CH - nothing. Boiler lights when I put HW on though (as before). Valve not moved and, in fact, manual lever very tight (expected maybe if the HW is on?). When I put both on, it...

Yep, all checked out. The lever moves to the middle fine and then the cog bit moves the rest of way with some light finger pressure. Can hear the microswitches click on/off too. All looks good there.

Well, deffo no black button on the back of the actuator. There is a label that says 'warranty expires 12/99' so that might give an indication of age!! ;) This is what it looks like with the motor off - not sure what to do next though.

Ok. I was operating on the basis that my valve was one of those older ones where the white box part doesn't detach from the valve but I'll check for a black button tonight.

Ah, right. So I'd turn the leccy back on without the motor attached and then put the CH/HW on and move the manual lever to the appropriate positions? If so, I can try that tonight.

If you mean the CH/HW functions work if I manually move the lever - yes, they all work fine. On the basis that the original motor had gone, I've replaced it but no different really. Confused me that it worked normally (briefly!) on Saturday though!

Hi all Still ongoing (but the weather means it's not a high priority!). On Saturday, I decided to take the motor off the valve again (I'd fitted a new one) and have a play about with the manual lever - wasn't sure where to place it before fitting motor, etc. When I did that, I just left it...

Sorry - that's my pic. If you turn that pic 90 degrees clockwise, it'll be like it is in reality. The narrow pointy part of the motor is pointing up.

Hmm, was wondering about sludge (although didn't think that would affect the valve working correctly or not). When I used the bleed valves on a couple of radiators (to check for air) I did notice the water was quite dark, even black, quite briefly before running clear-ish. Might be some...

Hi all Been a while since I did anything on this but problem continues. Since my last post, I've replaced the motor in the valve with a new one but I don't think anything has changed. The 'H, M, W' indicator needle still doesn't move to 'H' when I put just the heating on although, perhaps...

Cool (like it is in my house ;)). Does that make it most likely to be the motor then? Must admit, using the manual switch on the top, it does seem to move quite freely between the different positions so assume the mechanical part of it is ok...

Righty - I've flicked the big switch back and I seem to be back to square one (which isn't necessarily a bad thing) - that is, the stat is ok (22 degress or something) and with the heating and the hot water on, the vale is pointing to 'W'. The radiators are cold. When nothing is on, I put the...

Thanks for the quick replies. I do have a room stat and I've tried turning it right up and down but no real change. It does make a quiet click at about 18 degrees - I assume the temp it's sensing and thus trying to turn on/off as required but the boiler doesn't burn. I did have the motor...
