Samsung dishwasher 5C error: what it means and how to fix it

Also shown as SC, 5E, SE, SR.

What 5C means

The dishwasher is not draining water the way it should. You’ll usually find a clog or kink in the filter area, sump/drain hole, or drain hose.

Samsung’s manual for code 5C says: after closing the water supply valve, check whether the drain hose is clogged or folded, and check whether the drain hole inside the sump is clogged. If the problem continues, contact an authorized Samsung service center. (p30)

Safety first

Close the water supply valve. If you need to access hoses behind/under the unit, turn off power at the circuit breaker before you move or inspect anything.

Stop and call for service if:

Common causes

How to fix it

  1. Close the water supply valve (as Samsung instructs for this code).
  2. Clean the dishwasher filters: turn off the dishwasher, remove the filter insert (rotate counterclockwise) and the fine filter, remove all dirt/food, and rinse under running water. Reassemble and make sure the filter insert is closed properly.
  3. While the filters are out, check and clear debris around the drain hole/sump area (the pit below the filters) so water can exit freely.
  4. Turn off power at the house circuit breaker before checking anything behind the dishwasher, then inspect the drain hose for folds/kinks and straighten it. (A folded hose can stop draining.)
  5. Still with power off, check whether the drain hose seems clogged and look for signs of downstream blockage mentioned in the video (for example, water spraying from an air gap during draining).
  6. If the dishwasher drains completely but water comes back hours later, check the backflow/check valve near the drain connection and clean/replace it (video guidance).
  7. After each change, reassemble parts and run a test to confirm it drains. Keep up regular filter cleaning to prevent repeat 5C errors.
