I have searched high and low, but apparently I'm the only one in the world to ever purchase the SHX6 model of dishwasher. Since this model has very few buttons on top, none of the diagnostic routines I can find online apply, even those for dishwashers in the same series. Does anyone know how to run diags on this model?

The issue is that the washer is not filling with water. I can hear a solenoid or motor sound for several seconds, then the cycle runs for about 1 minute (dry), then it beeps CLEAN. Any suggestions to diagnose? I assume either water valve or control board, but am not sure if there is also a fill switch water pressure switch also that might have failed?
