GE Dishwasher Fills But Won't Wash: Wash Pump Fix

Quick Answer

A GE dishwasher that fills with water but does not start washing has water in the tub but the wash pump motor is not running. The most common causes are a failed wash pump motor, a motor start capacitor fault, or a door switch intermittently dropping out after the fill phase. Test the wash pump motor with a multimeter (should read 5-15 ohms) before ordering parts.

The most common causes are a failed wash pump motor, a motor start capacitor fault, or a door switch intermittently dropping out after the fill phase. Test the wash pump motor with a multimeter (should read 5-15 ohms) before ordering parts. If the motor hums briefly then stops, a seized impeller from a debris jam is the likely cause.

What Does the FILLS-NO-WASH Code Mean?

Fills but won't wash means the fill valve works but the wash pump does not. Test the pump motor first. A hum with no movement indicates an impeller jam. No hum indicates a motor or control board fault.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Wash pump motor impeller jammed with debris (glass, bone, label)40%
Wash pump motor winding failed24%
Control board not sending voltage to wash pump after fill22%
Door switch dropping out between fill and wash phases14%

Symptoms You May Notice

  • Water fills tub normally but no spray after fill phase
  • Humming sound from pump area but no water movement
  • Cycle timer advances but no cleaning action
  • Water sits in tub for entire cycle duration

Can you reset a Ge dishwasher to clear the FILLS-NO-WASH code?

Hold Start/Reset for 3 seconds to drain the tub before servicing. After repair, turn the breaker off for 30 seconds to reset the control board before running a test cycle.

Frequently Asked Questions

Why does my GE dishwasher fill with water but then do nothing?
The fill valve is working correctly but the wash pump is not starting. This usually means the pump impeller is jammed with debris or the pump motor has failed. Listen for a hum at the start of the wash phase - a hum indicates a jammed impeller, silence indicates a dead motor or board fault.
Is it worth replacing the wash pump on a GE dishwasher?
Yes in most cases. The wash pump assembly costs $65-120, and a dishwasher pump replacement is a straightforward intermediate repair. If the dishwasher is under 8 years old, pump replacement is the clear choice over replacement.
