Dishwasher won't fill

01 - Dishwasher Water Inlet Valve
The water inlet valve opens to allow water to enter the dishwasher. If the water valve is clogged or defective, water will not flow into the dishwasher. Water inlet valves are not repairable—if the valve is defective, you must replace it.

05 - Water Supply Problem
Over time, calcium deposits can build up in the water supply valve or in the small filter screen inside the water inlet valve. If the water inlet valve is clogged with sediments, the dishwasher won’t fill properly. Before working on the water line, first shut off the water supply. Inspect the valve to determine if it is clogged. In addition, check the water pressure to the valve. The water inlet valve requires at least 20 psi to function properly.
06 - Dishwasher 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 appropria...tely, it should be replaced.
