Cause 1
Water Pump Belt
The water pump belt might be worn or broken. However, few dishwashers have a water pump belt, you should search for your model number to determine if it has a water pump belt. To access the water pump belt, remove the lower panel. The water pump belt is located on the bottom of the motor. If the water pump belt is broken or worn, replace it.
Cause 2
Water Inlet Valve may have failed again
The water inlet valve opens to allow water to enter the dishwasher. If the valve is clogged or defective, the dishwasher won’t get enough water to clean dishes properly. If the water inlet valve is clogged, replace it. Do not attempt to clean the water inlet valve—cleaning the valve could make it more likely to fail.
Cause 3
Lower Wash Arm Assembly
The lower wash arm circulates water to the dishes in the lower rack. If water can’t flow properly through the lower wash arm, the dishes in the lower rack won’t be cleaned properly. Over time, food particles can get trapped in the tiny holes in the wash arm. If your dishes are coming out dirty, the wash arm might be clogged. To unclog the lower wash arm, remove the wash arm and dislodge any debris from the holes. If the wash arm is extremely clogged, replace it.
