Flow meter

Find the little pulse-counting turbine spliced into the fill plumbing where water enters the tub, and treat this as a metering fault since that wheel is how the board tallies how much water went in
Unplug its connector and check the pins for the hard-water crust and green film that build up down in the base and choke the signal
Set a meter to catch the pulse train while water runs through it — a steady chatter of pulses means the wheel spins and reports, a flat line means it does not
Split the fitting and look for scale or grit wedging the paddle wheel; a turbine stalled by deposits sends no count even though water is clearly flowing
Only with clean contacts and a paddle that spins freely, yet still no pulse, does the meter get renewed
Pro Diagnostic Tip
This pulse turbine took over from the old float switch to measure fill by volume, so when it lies the machine mis-fills: stuck reading no-flow it keeps filling and floods, stuck reading full it starves the wash. In hard-water country the paddle wheel furs up with scale and stalls — a vinegar soak of the turbine body often revives it before you spend on the sensor.
