Samsung Dishwasher Error Code 3C
Pump motor error
Common Causes
- 1Pump motor failure
- 2Wiring issue
Step-by-Step Troubleshooting
- 1
Check for a jammed pump impeller: remove the filter assembly and look into the sump area for broken glass, bones, or other hard debris that could jam the pump
- 2
If the sump is clear, the wash motor or drain pump motor may be failed. Access the pump assembly by removing the lower access panel (kick plate) and the base plate beneath the tub
- 3
Test the wash pump motor for continuity — it should read between 5-20 ohms across the terminals. An open reading confirms a burned winding
- 4
Check the pump motor wiring harness connector at the main control board for corrosion — Samsung dishwashers can develop connector corrosion from the humid environment inside the machine
Pro Diagnostic Tip
Samsung dishwashers use separate wash and drain pump motors. Listen carefully: if you hear humming but no water movement, the wash pump is seized. If the wash pump works but water does not drain, the drain pump is the issue. The 3C code does not distinguish between them.
You Might Also Notice
- •No water spraying during the wash cycle
- •Humming noise from the base of the dishwasher
- •Water remaining in the tub after the cycle completes
