Samsung Dishwasher Not Draining? Check These Troubleshooting Steps

You will need to know what the issue is before you can resolve it. The good news is that there are some very easy troubleshooting steps you can take to make sure your dishwasher drains properly again.

1. Samsung Dishwasher Not Draining Error Codes:

The first step in fixing the Samsung dishwasher is to check the error codes. The error codes are printed on the display screen, and they tell you how to fix the problem and what part of the machine is causing the problem.

A drain or overflow error is indicated by error codes 5C, 5E, OC, or OE. You can check your Samsung manual that comes with your dishwasher to troubleshoot these errors.

2. Check the Drain Hose:

This is usually caused by an excessive build-up of limescale, which creates a blockage in the drain hose.

If the hose is not properly connected to the drain, this can also cause the dishwasher not to drain properly. 

To fix the problem, you must disconnect the drain hose from the drain sink, clean the hose, and reattach it to the drain sink.

If the drain hose becomes clogged, it may easily be cleaned with soap and hot water. 

For some models of Samsung dishwashers, you may need to disassemble the drain valve and manually unblock the drain hose.

3. Clean Filter:

If you have already done all the troubleshooting steps and your Samsung dishwasher still doesn’t drain, there could be a problem with the filter.

If the filter is dirty, it can clog your drain hose. You may either replace the filter or clean it manually to solve the problem.

You must first remove the filter before replacing it. To loosen the filter, you’ll need to use a tool. After that, you may install the new filter.

The best way to clean the filter is to use a soft bristle brush and a can of spray cleaner.

4. Inspect the Sink Drain:

A blocked sink drain is the most common problem with the Samsung dishwasher. This problem can usually be solved by turning the water valve back on and allowing the drain to drain completely.

If you feel the issue is with the drain, follow these procedures to resolve it.

  • Turn off the appliance’s power source.
  • Lift the drain hose away from the sink.
  • Check for any blockage.
  • If a blockage is visible, use the equipment that came with the appliance to remove it.
  • Unscrew the pipe clamp or drain fitting that holds the hose in place and remove the drain hose.
  • Make sure the drain hole is clear. Reattach the drain hose.

If you can’t get rid of the clog on your own, you should get a professional plumber to clear the drain.

The plumber will use a cleaning solution to clear out any debris and will then use a snake or drain auger to clear out any clogs.

5. Try Using a Different Rinse Option:

Changing your rinse option can solve a lot of problems. This includes the option of the wash cycles, temperature setting, and the amount of water in the dishwasher.

It could be that your current rinse option is not working properly, and that’s why your dishwasher isn’t draining.

To fix this problem, you must remove all the items in the dishwasher. Then, you can use the default rinse option. You can also try using a different rinse option.

6. Check the Water Level:

It’s possible that the dishwasher is not full enough. There might be an issue with the water level in your Samsung dishwasher if it is not draining.

If the water level in the dishwasher is too low, it will be unable to drain the water properly.

To check the water level, you will have to lift up the door and look inside the dishwasher.

Ensure that the water level is at the minimum setting. If the water level is too low, add more until the dishwasher is full.

Make sure that the water level is as it should be. If the water level is low, this can cause the drain hose to get blocked. Once a week, you should check the water level.

7. When Your Samsung Dishwasher Won’t Drain, Look For Failed Parts:

Another reason why your Samsung dishwasher won’t drain is that there are some parts that have failed. This could be caused by damage or by corrosion that has happened over time.

To find out what is wrong with your appliance, you need to check the parts. The following parts of the Samsung dishwasher can fail and prevent it from draining:

Water valve: A malfunctioning water valve can cause the dishwasher not to drain. You can check the water valve using a wrench. If you find a crack in the valve, it can be fixed by replacing it.

Drain hose connector: Some models of Samsung dishwashers have a connection where the drain hose connects to the dishwasher. In this situation, the connector might be loose, or it could be blocked.

If the connector is blocked, it can prevent your Samsung dishwasher from draining properly. Replace it to fix the problem.

Failed Drain Impeller: If you notice that the impeller in the drain has failed, you will need to replace the whole impeller. A clogged drain hose or an incorrectly attached hose to the drain might also cause it.

Broken Drain Solenoid: The drain solenoid is a small valve that opens and closes the drain. It should work automatically. The drain hose will not close, and the water will not drain from the dishwasher if the drain solenoid malfunctions.

The drain solenoid can be replaced to solve the problem. It is normally installed near the door of the dishwasher.

Faulty Drain Pump Motor: The drain pump motor is a motor that moves water through the drain hose. If the motor malfunctions, the water in the drain will stop draining. You can replace the motor to solve this issue.

8. Contact Samsung Customer Service:

If you have tried all the steps listed above and your Samsung dishwasher still won’t drain, it is time to contact Samsung Customer Service.

You can contact Samsung Customer Service through the following methods:
