Cause 3Water 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 is clogged. In addition, check the water pressure to the valve. The water inlet valve requires at least 20 psi to function properly.
