the red (lead) wire on my honeywell v4043h1056 motorised valve is loose.the heating does not come on anymore until the wire is moved.when this happens the heating comes on for a limited time sometimes only a couple of seconds.any ideas how to remedy this?
We have a motorised valve with faulty wiring and its performance was spasmodic.
If it is not connected to the boiler wiring ,the boiler does not light at all when firing c/heating only.
Until the wiring is tight and fixed the boiler will be spasmodic
