GE Dishwasher Not Draining: Step-by-Step Fix

Common Symptoms

• Standing water (1–2 inches) at the bottom of the tub after the cycle
• Dishwasher stops before completing the cycle
• Humming or buzzing sound at end of cycle with no drainage
• Error code (usually PF or a flashing light pattern) on GE models
• Water smells stagnant or mildew-like

Most Likely Causes

1. 1

   Garbage Disposal Knockout Plug Not Removed

   When a new garbage disposal is installed and the dishwasher drain hose is connected to it, the factory knockout plug inside the disposal must be punched out. If it was never removed, the dishwasher can't drain at all. This is a very common cause on new installs.

2. 2

   Clogged or Kinked Drain Hose

   The drain hose runs from the pump to the garbage disposal or sink drain. Over time, grease and detergent can build up inside the hose, or it can kink if the dishwasher was shifted. The hose should form a high loop under the counter to prevent backflow.

3. 3

   Clogged Drain Pump or Filter

   GE dishwashers have a pump at the base of the unit. Glass shards, food chunks, and debris can jam the pump impeller. Many GE models also have a filter that needs periodic cleaning.

4. 4

   Failed Drain Pump Motor

   If the hose and filter are clear but the dishwasher still won't drain, the pump motor may have burned out. You'll typically hear a hum or click with no water movement.

Quick DIY Checks

1. 1Check if you recently installed a new garbage disposal. If so, locate the knockout plug inside the disposal's inlet port (where the dishwasher hose connects). Use a screwdriver and hammer to punch it out, then remove the plastic piece from inside the disposal.
2. 2Pull out the lower rack. Remove the filter basket at the bottom of the tub (usually lifts out or unscrews). Clean out all food debris and rinse under water. Check the drain opening for foreign objects.
3. 3Follow the drain hose from the back of the dishwasher to the disposal or drain. Check for kinks or clogs. Disconnect the hose from the disposal end and blow through it — it should flow freely.

1. 4Verify the high loop: the drain hose should be looped up as high as possible under the counter before dropping down to the disposal. A missing high loop allows water to siphon back into the tub.
2. 5Run a short cycle and listen. If you hear the pump running (buzzing) but water isn't moving, the pump impeller may be jammed — turn off power and use a wet/dry vacuum to remove standing water, then inspect the pump for debris.
