I currently have hot water but no central heating
When I move the 3 way valve to the H position manually the boiler fires up and I get Hot radiators
When I switch the programmer to Hot Water only then the valve moves automatically to the W position
If I then switch the hot water off and the Central heating on the mid way valve stays in the W position and the boiler doesn't fire up
It will fire up when I move the switch manually again to the H position
Does the actuator need replacing or could the fault be elsewhere?
Any assistance appreciated
Depending on the make of the valve and actuator, you may be able to replace the synchron motor inside the actuator, otherwise, it's the actuator itself.
