help with 2 way valve

[blondie465]

Hi. I am total novice at this stuff so apologies for mistakes. Have a prob with two port valve on HW. lever was moving manually but boiler would not light for more than a few seconds. Asked a friend who is more knowledgeable than me (not much!) and he advised that the motor inside the valve could be broken? After sometime and research, managed to change motor inside valve (yay!) when I move the lever now the boiler comes on which is good but I used to be able to just select "on" on my timer and this happened automatically, so have a done something terrible wrong? Grateful for any advice!

Change the whole head sounds as if you have a dead board in the head.

Thanks for your advice Jordon. When you say head do you mean the whole silver housing of the valve or something on the time clock, should I get a professional to attempt this, or can I do like with the motor and just turn everything off and copy wires as before?

Hang on. You say you have replaced the motor and it still won't operate automatically via the programmer. Changing the head may not solve your fault. Check your cylinder stat is at 60c. Do you have a multimeter with the skill to use it? as there are several things to check before changing parts. If not then a half decent repair man will find your fault in no time. It sounds like you have a Honeywell valve?

You may be able to do it if you have a five way click box. Yes the silver box, is it honeywell stamped on it or tower? When you remove the cover there is a screw top and bottom comer to remove the whole head, cut the black cable use the click box to pair the wires back up.

Yes it says honeywell on it and a number starting V4043 or 8 I think, hard to see now. Timer says drayton and then there is box where all wires seem to go in that also says honeywell. Was all working before so could the fact that it stopped working have changed the cylinder stat (I'm assuming this is the actual hot water tank you mean?!). Again apologies if this is all a bit basic and I am being a moron.

If you have correctly replaced the motor and it still doesn't work then fitting a new head is not the answer unless the motor you fitted is defective. Diagnose the fault first.
