Will someone please help me.?
I have a Vaillant boiler no problems.
This morning I discovered that my water and radiators weren't working. I went downstairs and fiddled with the Thermostat moving it up and down went upstairs discovered the boiler started to fire and all was working.
This evening the same thing happened and I followed the procedure above and all's working.
DO I NEED A NEW THERMOSTAT ? THANK YOU
