Samsung Dishwasher Not Draining [9 Causes Revealed]

A common problem with Samsung dishwashers is that the dishwasher will not drain.

This is one of the most common problems that people encounter.

Food particles clogging the filter, drain hose, or pump assembly are the most common causes of this malfunction.

Another possibility is that the problem is caused by a faulty drain pump, solenoid valve, or check valve (flapper).

If your Samsung dishwasher parts are not draining properly, follow these steps to determine and resolve the problem.

Remember to unplug the dishwasher from the power source and turn off the water supply before attempting any of these repairs on the appliance.

Caution!

Codes for “No Drain” Errors

Some Samsung dishwasher models will display error codes to alert you that there is a problem with the draining. Among the codes that you may come across are the following:

Delicate light flashing at 5C SC 5E SE OC or 0C DELICATE light flashing

Error Codes That Are Not Correct

The presence of false error codes is also possible in some instances. That occurs when the dishwasher displays any of the error codes listed above, indicating a draining problem, despite the fact that the appliance continues to operate and drain normally.

Additionally, while this problem is occurring, the dishwasher may stop in the middle of a cycle after 9 minutes for no apparent reason.

If this is the case, it is possible that the problem is not with the drain, but with the Drain Sensor or the Samsung Dishwasher ECS Sensor. Unfortunately, over time, these sensors suffer from wear and tear, and they may become dirty or fail altogether.

As a result, you’ll have to track down and clean these sensors. It will be necessary to replace it entirely if this does not work.

What is the cause of your Samsung dishwasher not draining?

Consider the scenario in which your Samsung dishwasher error code does not drain properly at the end of the cycle.

Here are nine possible explanations for why this might be the case, as well as what you can do about it.

1. The Drain Hose is Clogged.

What it is: The drain hose is responsible for allowing all of the dirty and used water from your dishwasher to flow out into your home’s drainage system. Because the dishwasher is typically located in the kitchen, the drain hose is connected to the same drain as the sink, or it may share a drain with the garbage disposal if both are installed in the same location.

How it fails: If there is something in the way of water flowing wash cycle through the drain hose, your Samsung dishwasher will have a difficult time draining all of the water from the dishwasher filter.

First and foremost, it is possible that the hose has become kinked, thereby restricting the flow of water. When the dishwasher and the sink share the same drain, this is more likely to occur.

However, if the appliance and the garbage disposal share the same drain, make sure the drain water flow isn’t clogged with food bits or other debris before using the garbage disposal.

2. Examine if the valve is worn out.

What itis as follows: A check valve can be found somewhere along the length of the dishwasher drain hose, but it is not always visible. It is necessary to use this valve to ensure that water only flows in one direction, namely away from the dishwasher. The dirty water is prevented from re-entering the dishwasher as a result of this preventative measure.

Check valve failure occurs when the valve becomes stuck in either the open or closed position, depending on its condition. Any water that is being drained out of your Samsung dishwasher will be prevented from flowing into your home’s plumbing if it becomes stuck in a closed position.

As a result, your dishwasher will be unable to drain properly and will display the appropriate error codes.

In the event of a faulty check valve, the first step is to clean the valve and reinstall it in the proper position. It is possible that this will clear away any dirt or debris that may be causing the valve to become stuck in the closed state.

However, if the check valve continues to cause problems even after you’ve cleaned it, it’s best to replace it with a new one instead. You can get a new check valve for a reasonable price, and it will last you for a very long time.

3. Confirm that the dishwasher is the source of the problem.

Check to see that the dishwasher drains properly by running water through the sink that is connected to it.

If the dishwasher is connected to garbage disposal, check to see that it is not clogged with food debris. It is important to check that the garbage disposal knockout plug in the garbage disposal’s drain tube has been removed if the dishwasher was recently installed.

4. Inspect the connection between the dishwasher and the sink.

Dishwashers require that the drain hose be connected to either an air gap or that the drain hose has a high loop in order to function properly. These features are in charge of preventing the wastewater from the dishwasher from being recycled back into the dishwasher.

Most of the time, the air gap is a fitting that is mounted to the sink or kitchen cabinet. By forcing air into the hose, it eliminates the negative pressure that can cause wastewater to be redirected back into the dishwasher after being discharged.

It is possible to use the “high loop” method by looping the drain hose so that it is secured just beneath the sink.

Dishwashers that are not equipped with high loop drain hoses or that have an air gap that is clogged may have difficulty draining properly. By removing the cover and cap, you will be able to inspect and clean the air gap of any debris.

5. The Drain Pump Has Failed

What it is is as follows: A drain pump can be found at the bottom of your Samsung dishwasher. Using an impeller, this electrical component forces all of the used water out of the dishwasher and into a collection container. It accomplishes this by pushing the water through the drain hose and into your household plumbing system.

Draining issues can be caused by a faulty drain pump, which is described below. It is possible for this component to malfunction in two ways: electrically or mechanically.

For example, the pump could short out due to an electrical fault, or it could burn out as a result of excessive wear and tear over the course of several years. A foreign object could mechanically jam the impeller, causing it to malfunction. If the impeller becomes stuck, it will be unable to drain the water trapped inside.

6. Remove the filter, drain hose, sump, and tub and clean them.

Depending on your Samsung dishwasher model, you may or may not have a removable filter installed. Removing the filter may also provide you with an opportunity to clear the drain pump of any debris that may have accumulated there. Instructions on how to remove the filter from your dishwasher can be found in the owner’s manual.

If your model has a filter assembly or pump cover that can be removed to gain access to the components, removing the screws and cleaning the filter and pump assembly may be sufficient to resolve the drainage problem in your model.

The filter or pump cover should be replaced if they are damaged in order to avoid further damage to the pump and motor seals.

Disconnect the dishwasher‘s power and water lines before attempting to access the filter and pump assembly for your own safety.

A dishwasher cleaning product, or white vinegar, can be used to break down food particles and minerals that have accumulated and may be preventing the dishwasher from draining.

White vinegar can be used in this recipe; simply pour 1-2 cups into a dishwasher-safe bowl and place it on the top rack of the dishwasher. Closing the door and continuing with the normal cycle follows after that.

7. Inspect the drain hose for obstructions or kinks.

It is possible that a clogged or kinked drain hose is preventing the dishwasher from draining. First, make sure that the drain hose is not kinked, which may have occurred as a result of the way the dishwasher was installed.

Run a cleaning solution through the dishwasher, following the instructions in step 3. If the problem persists, the drain hose should be disconnected from underneath the sink and thoroughly inspected for obstructions.

As soon as the hose has been disconnected, place the other end in a large bucket and run a short cycle through the machine. This may result in the blockage blowing out into the bucket or demonstrating that the pump is not functioning properly, depending on the situation.

Make certain that you are prepared to turn off the dishwasher or that you have another bucket on hand to collect the water that has been discharged from the dishwasher.

The bottom front kick plate or access panel underneath the dishwasher will need to be removed in order to inspect the location where the drain hose connects to the pump and, if necessary, to remove and clean it.

8. Inspect the solenoid valve for damage.

Depending on the model, the dishwasher may be equipped with a drain solenoid valve, which opens when the water is ready to be discharged. It is possible for the solenoid to become faulty as a result of abnormally high or low temperatures.

During a failure of the solenoid, the valve will not open, preventing the dishwasher from draining.

The drain solenoid can be tested with a multimeter in the same way that the pump motor was to determine if it has continuity. If the solenoid is faulty, it should be replaced as soon as possible.

The solenoid is typically found near the motor or on the drain pump. It can be accessed by removing the bottom front kick plate or the bottom access panel from the bottom of the front kick plate.

9. A clog in the water inlet assembly

What it is is as follows: Draining your Samsung dishwasher will require you to run the water through the water inlet assembly on your way to the drain hose and out of the appliance.

The failure mode is as follows: Assuming you’ve eliminated all other possibilities, it’s likely that the water inlet assembly is the source of your dishwasher draining issues.

Please keep in mind that water passes through the water inlet assembly on its way to the drain hose and out of the appliance. As a result, naturally occurring blockages at the water inlet assembly, consisting of food bits or other particles, can occur.

The longer this obstruction is left unresolved, the more severe it will become until no water is able to pass through it anymore. Your Samsung dishwasher will begin flashing the appropriate error codes at that point.

How to correct: To correct this, you’ll need to remove the obstruction. Begin by removing the left-hand panel on your dishwasher, which is located above the water inlet assembly. Following that, you’ll notice a number of grey hoses attached to the assembly, which you’ll want to disconnect as well.

Using your fingers or a small brush, you should be able to clear any obstructions that have formed while the hoses were removed.

How to Troubleshoot a Samsung Dishwasher That Isn’t Draining Properly

Step 1: Examine the sink drain.

If you have a garbage disposal that shares the dishwasher’s drain, make sure it’s clean and free of blockages before running the dishwasher. A newly installed disposal may still have its cap on, preventing dishwasher water from draining properly. To allow water to flow freely, make sure the cap is removed. If you don’t have a garbage disposal, clear any visible obstructions in the sink drain.

Step 2: Inspect your Samsung dishwasher’s drain hose.

Do you want to know why there’s water in the bottom of your dishwasher? Puddles in the dishwasher can indicate that the drain hose was not properly installed.

Here’s how to tell if your Samsung dishwasher drain hose is properly positioned:

  1. Make sure the dishwasher isn’t resting on the drain hose and pinching it shut.
  2. To prevent water from entering, the hose must be either connected to an air gap or have a high loop above the sink connection.
  3. Before using the hose, inspect it for kinks or other damage. While a kinked hose can be straightened with gentle pressure, a damaged hose may need to be replaced.

Step 3: Make sure the sink drains properly.

You can check that the sink is draining properly by running the water for 30 seconds. If water is backing up or draining slowly, a plumbing problem in the home, rather than the dishwasher, could be to blame.

Clean your Samsung dishwashing machine’s drain, filter, and sump.

To unclog a dishwasher that is not draining properly, thorough cleaning of the drain, filter, and sump may be required.

Cleaning a Samsung dishwasher’s filter, drain, and sump is simple if you follow these steps:

If the filter is removable, thoroughly rinse it under warm running water, brushing it with a soft brush to remove any stubborn particles that may have accumulated.

Pour the drain, then remove the filter to access the drain pump cover. Pushing the handle upwards allows you to pull up the drain pump cover and clear away any visible debris.

After cleaning the area around the drain, make sure the sump at the bottom of the drain is clean. If there are any visible obstructions inside the sump, use a straightened clothes hanger to remove them.

It’s possible that a faulty part is causing your dishwashing machine to not drain.

If your Samsung dishwasher is still not draining after following these troubleshooting steps, a component may have failed.

The following component failures can cause Samsung dishwashers to drain improperly:

Failure of the drain impeller: The impeller is in charge of pushing water through the drain pump and into the disposal or sink drain. If the impeller wears out, it must be replaced.

Drain Pump Motor Failure: When the motor fails, the drain pump is unable to function, rendering the pump inoperable. When tested with a multimeter, if the motor fails to maintain continuity, the entire pump must be replaced.

Drain Solenoid Failure: When the solenoid fails, the drain valve opens, allowing water to drain. It will need to be replaced if it breaks.
