Most Frequent Causes for Dishwasher not cleaning

Cause 1Water Inlet Valve

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 2Lower 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.

Cause 3Pump and Motor Assembly

The motor drives an impeller to force water up through the wash arms. If the motor is defective, the pump impeller is broken, or some part of the pump is clogged, dishes won’t be cleaned properly. Make sure that power is getting to the circulation pump and motor. If power is getting to the pump and motor assembly but it still won’t run, replace the pump and motor assembly.
