oh!! yes when i push the lever across and hooked it in position the pump and boiler started to work!! does this mean the motor is def. worn then and obviously not motoring across and switching on the pump and boiler automatically? new valve?

ok thanks for confirming that with me. so if white is live but ornage is not, then the valve motor is faulty. i might just replace the whole valve to be on the safe side and then it'll all be nice and new. but what about the backread signals situation? is this true or do i need not...
