Bosch Dishwasher Won't Fill?

macman

Some friends of mine have a Bosh Excel full size dishwasher, model no. SGS 43 A02 I think. They moved it from one house to another. When installed, it worked fine for one day, but now refuses to fill on any programme, but will pump out OK. They've checked the filter on the supply side, there is pressure at the inlet pipe, hose not kinked, have checked and cleaned the pump and internal filters.
Someone else mentioned a possible sticking float valve, is this a likely cause after it's been moved around? If so, how is this accessed?
They're panicking at the thought of Christmas spent in front of a bottle of Fairy Liquid...

The Bosch Exxcel range of dishwashers have an Aquastop valve in the inlet hose, it is an electrically operated valve with the cable running to it through the hose, I think it is supposed to stop the machine from overfilling and flooding.

Bosch state to be careful not to get any water in this valve or it will not work, just a thought, maybe they have managed to get it wet while disconnecting and moving the machine.
