We have three 2-way valves in our system - one each for hot water, upstairs heating and downstairs heating.
Noticed that the downstairs heating not working and narrowed it down to the valve. I've bought a new motor from screwfix, which has made no difference. I've then changed the entire housing of the valve as I thought the gear mechanism may be shot but that has made no difference. If I remove the housing and move the valve spindle manually, it turns fine.
I'm now at a loss as to what is actually wrong with it. Any advice please?
