Samsung Dishwasher Error Code 5C
Drain error
Common Causes
- 1Clogged filter
- 2Kinked hose
- 3Drain pump issue
Step-by-Step Troubleshooting
- 1
Remove and clean the filter assembly at the bottom of the tub — this is the #1 cause of Samsung dishwasher drain codes
- 2
Check the drain hose under the sink: it should be connected to either the garbage disposal knockout or a high-loop on the drain pipe. Verify no kinks and that the connection is clear
- 3
If a garbage disposal is installed, ensure the knockout plug has been removed from the disposal inlet. A forgotten knockout is a common issue with new disposal installations
- 4
Bail out remaining water from the tub and run a drain-only cycle. If the drain pump makes no noise, it may be failed. Access it from below and test for continuity (approximately 10-15 ohms)
Pro Diagnostic Tip
Samsung dishwashers require a high drain loop or an air gap to prevent backflow from the sink. If 5C appears after a sink backup, the drain water siphoned back into the dishwasher. Install an air gap or ensure the drain hose loops up to the underside of the countertop.
