I checked float after removal "inverted cup" cover, and it appears to be free and springs up and down when depressed. Normally when the control knob is set to START, then lever is latched, a humming sound is heard, then later the sound of water starts to spray and the cycle starts. Now it seems after the humming sound ends, all is quite... no noise is heard. When I manually turn the control knob through the cycle RINSE & HOLD, dry, etc. I hear a sort of solenoid type sound along the way, but no water is heard or seems to enter the wash compartment. Suspect more in depth issue with dishwasher.
