GE Dishwasher C5 Error Code

Pump-out time too short

What this error means

C5 means pump-out completed faster than expected—often pressure or float sensor anomaly.

How C5 is detected

C5 on GE dishwasher units indicates the drive system did not meet expected performance. Direct-drive washers monitor rotor position with a hall sensor; dryers and dishwashers track motor current draw. When the drum or spray arm fails to turn, the inverter or motor relay shuts down to prevent burned windings. GE GDT655SSJSS, GE GDF630PSMSS, and similar variants may show this fault after an overloaded tub or a foreign object jam.

Pressure sensor false empty is a leading trigger. Start with verify water actually left tub. Rotate the drum or spray arm by hand when powered off—it should move without grinding. Grinding confirms mechanical obstruction; free rotation with repeated C5 on light loads suggests hall sensor, motor, or inverter board failure requiring professional diagnosis.

Common causes

  • Pressure sensor false empty
  • Loose float sensor
  • Control timing corruption
  • Air gap siphon

Step-by-step fixes

  1. 1Verify water actually left tub
  2. 2Reseat float and pressure switches
  3. 3Power-cycle breaker 30 seconds
  4. 4Run full normal cycle test

When to call a technician

C5 with water still present needs sensor or control diagnosis.

Affected models

  • GE GDT655SSJSS
  • GE GDF630PSMSS
  • GE GDT225SSLSS

Prevention & maintenance

  • Avoid washing single heavy rugs or shoes that bind the drum; distribute weight evenly to reduce motor strain that precedes C5.
  • Record when C5 appears in the cycle and whether it clears after a 60-second power reset on your GE dishwasher—that detail speeds diagnosis if you call service.
  • Keep the model and serial number from the rating plate when ordering parts for C5; GE uses multiple revisions with different harness lengths and board firmware.
  • Photograph wiring connector orientation before disconnecting any component while troubleshooting C5; reversed plugs on pumps and valves cause immediate repeat faults.
