Other Causes and Conditions

Water Supply Problem

The dishwasher is connected to the hot water supply from the house. Check to be sure the household water supply valve is turned on. Over time, calcium deposits can build up in the water supply valve or in the small filter screen inside the water inlet valve. The water supply line may need to be removed from the water inlet valve of the dishwasher, then run some water into a bucket to see if there is enough pressure. Be certain to turn off the water before working on the water line.
