Vaillant Turbomax VUW GB 242 E - no hot water?

CH works fine. DHW works when CH is on. No DHW when CH is off.

White rocker arm isn't pushing down the microswitch when DHW is called for. I've replaced the diaphragm but still the rocker arm won't budge. Any ideas as to where the fault lies? Is it time for a new diverter valve?

Help greatly appreciated.

Cheers

I meant to add that if I have the diaphragm section opened & push up on the "plunger" the diaphragm would normally move, this doesn't move the rocker arm either.

Any ideas appreciated.

Cheers
