Hi folks, so I switched the heating on for the first time since spring and I'm getting nothing.
It's a worcester greenstar oil combi boiler. The hot water still heats as it has done all summer.
I've had a look at the diverter valve. The control unit was very stiff coming off (drayton box) and there were blue corrosion stains round it but the needle moves from A to B when changing between central heating/ water and the spindle on the valve moves freely by hand so it doesn't appear to be stuck.
Am I missing something stupid, or could the valve be stuck in one position but the spindle still moves?
I'd appreciate any advice please, thanks
