Most common is a burnt out inlet valve. Turn off water and disconnect power. The valve on Bosch dishwashers is at the back on the bottom panel. The water feed pipe is attached directly to the inlet valve. The valve itself iis set into a small rectangular panel that is sometimes just clipped in or held with two screws at one end. Remove this panel and disconnect the two wires on the valve and disconnect the internal feed pipe. These valves are common on Neff, Siemens and Bosch dishwashers and washing machines and generic after-market replacements can be had for less than £10 (about £25 from Bosch). If it is not a defective inlet valve it could be a defective control board in which case the the cost of replacement has to be weighed against the cost of a new machine.
