Hi Phil, your particular flow meter is situated between the inlet valve and the side water jacket. To access it unplug machine,remove the left hand side panel(2 screws on front edge) you may have to remove the worktop to release the panel.The flow meter is a round white unit with blue pipes on it, remove the pipe that goes to the large water jacket, prise open the square panel holding the inlet water valve at rear and pull out meter through rear. Part is called an "impellor jug" part no 00424099. Cheers
