Samsung dishwasher 5C: The dishwasher cannot drain

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

The dishwasher cannot drain.

5C identifies a drain problem. Start with the sink connection and accessible hose rather than assuming the drain pump failed.

First safe check

Check whether the connected sink drains normally.

Samsung dishwasher families covered by the cited US guidance. Match the full model number and exact display; this is not an exact-model compatibility claim.

Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

Check the shared drain
Have a clogged sink or disposal cleared; after a recent installation, ask the installer to check the disposal knockout and hose routing.
What to note
The household drain is able to accept water.
Clean only removable owner parts
Follow the model manual for filter removal and reassembly, and check the accessible hose for kinks.
What to note
The filter and hose route are not visibly obstructed.

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

An air gap or high loop depends on local requirements and the installation manual. Incorrect reassembly of a removable filter can create its own drain problem.

When to stop and get help
