I hope someone can give me an idea about fixing this valve.
My CH stopped working yesterday but HW worked as normal. Boiler seems fine (only 3 years old). Heard it might be a faulty diverter valve so, with boiler power off, I moved the little levers from auto to manual. There was resistance and they whirred back to auto. Its an S plan system so I put the CH valve lever to manual and latched it. Switched on, and radiators heated up (although not as hot as usual).
The valve is a Honeywell F2 - 9421 and I believe its possible to just replace faulty parts rather than the whole thing.
Can anyone indicate what part could be faulty and how to replace it?
Thanks for any help!
