Thanks sorry late reply, your flow meter is called an 'impeller jug' part no 00424099, it is situated in the hose that runs from the inlet valve to the plastic side water jacket. To access it unplug from mains, remove worktop, remove left hand side panel remove hose from it that joins water jacket, remove small square panel that holds the inlet valve, disconnect wires to valve then pull valve out with impeller jug attached, replace impeller jug, refit all you undid, have a beer, job done. cheers
