Hi folks,
I have the above problem with my boiler and after reading through a lot of threads on here it sounded like the issue could be a faulty mid position valve actuator.
So I bought a new one, fitted it, but the original problem persists.
To give a bit more detail, if the HW is set to off and the CH on, the boiler does not fire.
If I then turn the HW on, the boiler fires up.
If I then turn the HW off, the boiler goes off, and then comes back on again. The heating can then be switched off and on with the programmer, or by turning down and up the thermostat (in the hall)
Does anyone have any ideas what the problem could be?
cheers.
