What does error code 5C mean on a Samsung dishwasher?

Drain error. The dishwasher can't drain the water out.

Can I fix Samsung code 5C myself?

Start with these safe checks: Clean the filter at the bottom of the tub. Check that the drain hose under the sink isn't kinked and that the sink drain itself isn't clogged. If the dishwasher was just hooked to a new garbage disposal, make sure the disposal's knockout plug was removed. If water still won't drain, request service.

When should I call a technician for code 5C?

If water still won't drain, request service. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
