On some models, there are 5C, SC, 5E, SE error or OC, 0C error might show up on the display.

All of these error codes mean that your dishwasher unable to drain water completely. DELICATE light flashing on the panel also means long drain error.

Here is list of possible failed parts and what you can do to troubleshoot your Samsung dishwasher when it’s not draining.

Drain Hose

Check dishwasher drain hose connection to the sink. Make sure that the hose is not kinked. If the drain hose connected to the garbage disposal, make sure it is clear of food waste and not clogged.

If the Samsung dishwasher drain hose connected to newly-installed garbage disposal, check to see if the knockout plug has been removed. The Knockout plug needs to be removed in order for the dishwasher to drain.

Check Valve

A check valve prevents water from returning to the dishwasher once it’s been pumped out.

If the check valve get stuck in the closed position or just been damaged, the water won’t drain properly.

You can try cleaning the valve, but if the problem continues you should replace the check valve.

Turn the water on to the sink. Let it run for about 30-60 seconds, and then verify if the sink drains.

If it does not, the issue is with the plumbing and not with the dishwasher itself.

Drain Filter

The next step is to check the drain filter. Drain filter located under the bottom rack.

Remove bottom rack and turn filter counter-clockwise. Now you can pull the filter out.

Drain Pump

The drain pump uses an impeller to force water through the drain hose if the pump motor is not working the water won’t drain from the dishwasher pump.

Pump motors can fail both electrically and mechanically.

You can use a Multimeter to determine if the motor is failed electrically by testing for continuity.

If the motor test negative for continuity it will need to be replaced.

Drain Solenoid

Some models of Samsung dishwasher have a drain solenoid valve that opens to allow the water to drain. If the solenoid fails the valve will not open.

As with the pump motor you can use a Multimeter to test the drain solenoid for continuity to help determine if the valve has failed electrically or not.
