Whether your dishwasher doesn’t live up to expectations or suddenly stops performing, no one appreciates the dirty dishes left behind. Why is your GE dishwasher not cleaning as it should? It may be too overcrowded for water and detergent to reach each item. Use these GE dishwasher troubleshooting tips to solve the problem and improve performance.

Common Reasons For a GE Dishwasher Not Cleaning 

While proper use and maintenance can result in cleaner dishes, sometimes a GE dishwasher not cleaning dishes needs a professional repair. These common causes detail how to pinpoint the problem.

Dishwasher Is Overcrowded

Overcrowding is one of the most common reasons a GE dishwasher leaves dishes dirty. Too many dishes placed too closely together leaves little room for water and detergent to reach every item. Overcrowding also increases the likelihood that objects will protrude outside the dish rack and block the spray arms’ rotation.

For the best way to load a dishwasher, follow these rack-by-rack tips:

  • Upper rack: Place bowls, cups and glasses upside down and at an angle to improve spray arm access.
  • Bottom rack: Place one dish per slot and position taller items along the perimeter of the rack to avoid blocking the spray arms.
  • Silverware basket: Alternate forks and spoons next to each other to prevent nesting.

Dishwasher Needs to Be Cleaned 

Has your GE dishwasher stopped cleaning like it used to? It may be in need of a cleaning. The tub, filter, and spray arms require regular cleanings to function optimally and prevent mold and odor.

These dishwasher cleaning tips can improve performance:

  • Tub: Place a bowl of white vinegar in the top rack of an empty dishwasher and run a complete wash cycle with hot water.
  • Filter: Remove the Fine and Ultra Fine filter and wash both with a sponge and warm, soapy water.
  • Spray arm: If you notice the dishwasher spray arm clogged with food, remove the arm and rinse it under running water. Remove clogs from spray arm holes with a straightened paper clip or pin.

Water Supply Problem 

Your dishwasher requires consistent access to your home’s hot water supply to properly clean dishes. 

The following water supply issues can affect your dishwasher’s cleaning power:

  • Water isn’t hot enough: In order to activate detergent and dissolve food stains, your dishwasher’s water must be adequately heated. Check your home’s hot water heater to make sure water is heated to at least 120℉. Running the hot water in the kitchen sink before starting a wash cycle can make it more readily available for the dishwasher.
  • Low water pressure: The dishwasher won’t fill with enough water if the pressure is too low. Make sure the dishwasher’s water pressure is between 20-120 psi. If the sink, washer or shower show evidence of low water pressure, a plumber may need to evaluate the issue.
  • Faulty spray arm or water inlet valve: Spray arm and water inlet valve malfunctions can restrict the dishwasher’s water supply. A GE dishwasher not spraying water may have a broken spray arm that requires replacement. If the water inlet valve is faulty, water from your home supply won’t be able to enter the dishwasher. A faulty water inlet valve should be professionally assessed and replaced.

Faulty Dishwasher Detergent Dispenser 

If you still find your GE dishwasher not cleaning dishes properly, it’s possible the detergent dispenser is faulty. If the dispenser doesn’t open at the right time, or at all, detergent won’t be released.

Sometimes grease and debris can clog dispenser components and compromise their function. While cleaning with hot water and vinegar can remove blockages, a damaged dispenser gasket or drawer requires replacement by a dishwasher repair service.
