[Albion] Faulty Boiler question

[Neil]

My Boiler will not turn off radiators when the programmer turns off the heating and stays on
I know its not the programmer because it has been changed and it did the same thing with the previous programmer
You can rectify the problem by turning the boiler off and on again.
What would cause this fault with the boiler itself?

 

[Cheshire Cat]

I think you need a plumber.

Presumably the programmer is not linking with the boiler.

 

[Elbow750]

It must be the programmer not linking with the boiler properly. The boiler only fires and runs or not, the programmer (and thermostat(s) tells it when to fire and when to stop.

Best get a plumber or electrician in.

Have you got a combination boiler or a boiler and hot water cylinder?

3 way valve sticking ? If it’s the hot water cylinder & boiler maybe ?

Yes that is what I thought

 

[Justice]

Is it wired correctly? I know it’s been changed although who ever did it you thought would of at least give it a test run.

 

[B-right-on]

Yes that is what I thought

Thats what happend to mine a couple of years ago. New actuator sorted it.

Changing the actuator usually works, if the motorised valve is a good one like a Honeywell or Drayton.

Exactly.. We need make, model and programmer..

Yep that sorted mine out as well

 

[Bodian]

Mine did the same a few years ago. They replaced the remote/wireless thermostat thingy and the diverter valve. Sorted it.


PS - good luck, bad time for it to happen (although at least it does come on)

Its an Ideal Icos Boiler with a Honeywell Sundial Y9420 Programmer with a hot water cylinder

Icos...quite a rare beast nowadays.. The boiler itself doesn't know if it's making CH or HW, so it will be ancillaries (wiring/programmer etc) - Given the programmer has been changed, it's very likely that 3 port zone valve gone.. If you are compentant, it's not that difficult to change the head only (depending upon age.. if the silver case has dimple, then it's simple. If doesn't, then required needs a drain down..)

This [or one of the valves in your airing cupboard, I'll wager - we get this exact same issue]

We live in a notoriously hard-water area and ours needs replacing every 3-4 years due to limescale build-up on the inside of the valve.
Since ours is also an "unvented system" we have British Gas homecare cover too

I had one of those valves in my old flat, it was a pain in the arse, the controller was fine but the valve itself used to stick.

I kept a pair of mole grips in te airing cupboard ;-)

 

[dazzer6666]

Had the same here, stuck 3-way valve was the issue.
