Dishwasher not cleaning

01 - Dishwasher Water 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.

02 - Improper loading
Improper loading will keep the water from cleaning the dishes. Make sure you are leaving enough space between the dishes.
03 - Improper water supply temperature
The water may not be hot enough. The recommended water supply temperature for a dishwasher to clean properly is 120 degrees Fahrenheit. If your hot water temperature is lower for safety reasons, try using a longer cycle that heats the water.
04 - Dishwasher Center Wash Arm Assembly
The center wash arm circulates water to the dishes in the upper rack. If water can’t flow properly through the center wash arm, the dishes in the upper 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 center wash arm, remove the wash arm and dislodge any debris from the holes. If the wash arm is extremely clogged, replace it. In addition, make sure that t...he center wash arm assembly is mating properly with the water supply nozzle.
