d/valve greenstar zwr

[gotbadgas]

quick question: does anyone know which way the divertor motor works on a w/bosch greenstar zwr 30kw jobby, cant remeber if on hot demand the motor pushes d/valve or backs off, basically doubting myself as cant remember for the life of me. hot water not working after heating demand so is the motor not pushing back or is divertor sticking back as a quick jiggle of motor allows hot water to be restored. its for a mate and left a bit prior to being certain

any ideas anyone?

In DHW mode the diverter valve plunger is retracted into motor head ie backs off.

so in your opinion do you think the motor could be sticking or the divertor itself sticking? like i said a quick jiggle on the motor allows it to work again but not sure what the jiggle actually helped the boiler do.....should of stayed longer and took a bit more notice. cheers

motor pushes the lever fully up for hot water mode. it maybe the motor sticking.
