About the Pressure Switch
A dishwasher pressure switch is the component that will send a signal to shut off the water inlet valve once an appropriate amount of water has entered the tank for a wash cycle. If the pressure switch is malfunctioning, it may prevent the inlet valve from opening and filling the tank. You can use a multimeter to test the pressure switch's terminals for appropriate changes in electrical continuity before and after blowing air into the attached pressure tube. If the switch does not test appropriately, it should be replaced.
