Samsung Dishwasher Error Code 3C: Pump operation error
Applies to Samsung dishwashers that show 3C on the display.
The wash/drain pump is not operating correctly.
What this code means
3C is the dishwasher's pump supervision code: the pump was commanded to run and its operation did not check out — usually a stall from debris, occasionally the pump itself.
The manufacturer's checks, in order
- Reset the dishwasher (breaker off, then on) and run a cycle.
- Check the filter and sump for debris that could stall the pump.
If 3C returns with a clean sump, the pump needs a service visit.
