GE Dishwasher Not Cleaning Dishes: Causes and Fixes

Quick Answer

A GE dishwasher not cleaning dishes is most often caused by a clogged spray arm nozzle, a blocked or dirty filter restricting wash water recirculation, water temperature too low (below 120F), or improper loading blocking spray arm rotation. On GE Adora and Profile models, the spray arm nozzles are small and clog with hard water mineral scale.

Soaking the spray arms in white vinegar for 30 minutes and clearing nozzles with a toothpick restores cleaning performance in most cases.

What Does the NOT-CLEANING Code Mean?

Poor cleaning on GE dishwashers is most often mechanical - clogged spray arm nozzles, dirty filter, blocked arms, or low water temperature. A vinegar soak of the spray arms fixes 40% of cases.

Frequently Asked Questions

How do I clean GE dishwasher spray arms?
Remove the arms by pulling straight up (lower arm) or unscrewing the retainer nut (upper arm). Soak in white vinegar for 30 minutes to dissolve mineral scale. Use a toothpick to clear each nozzle hole. Rinse under running water and reinstall.
Should I pre-rinse dishes before putting them in a GE dishwasher?
Light scraping is recommended but full pre-rinsing is not. Modern GE dishwashers use soil sensors in Auto Sense mode to adjust the wash intensity based on how dirty the water gets. Fully pre-rinsed dishes may actually cause the sensor to reduce wash intensity, resulting in less effective cleaning.
