Samsung Dishwasher Not Draining? – Troubleshooting Guide [2022]

It is essential that clean water flows into and dirty water drains out smoothly for a Samsung dishwasher to work effectively. It is possible that the water won’t drain from the inside of the appliance when you attempt to drain it. Furthermore, you may also experience Samsung dishwasher not draining issue from time to time.

A Samsung dishwasher that is not draining properly will display an error code that indicates a draining issue. If the drain hose is clogged, the fine filter may be clogged, or the drain pump may be faulty. Additionally, the drain solenoid and check valve may not open, preventing water from draining from the dishwasher.

Why is your Samsung dishwasher not draining and what can be done about it?


Please be careful!

Whenever you need to perform repairs on your Samsung dishwasher, disconnect it from the power supply first. By doing this, the danger of electrocution will be eliminated and any injury risks will be reduced.

It is also necessary to deal with water when working with dishwashers. Immediately after the appliance has been turned off, wipe up spills with towels.

As a final note, make sure you keep your user manual and any technical sheet on hand. Finding and identifying essential components can be made easier with the help of these documents.


Error codes that indicate “No Drain”

In some Samsung dishwasher models, draining problems are indicated by error codes. There are a number of codes you might encounter, including:

  • 5E

  • SE

  • SC

  • 5C

  • OC or 0C

  • DELICATE light flashing


Refer to the user manual of your Samsung dishwasher model to find out which error codes apply. An explanation of standard error codes can be found in this section.


Codes that indicate a false error

There is also the possibility of experiencing false error codes from time to time. The dishwasher will display any of the error codes listed above in this case, even though it continues to operate normally and drain.

Also, the dishwasher may stop mid cycle for no apparent reason after 9 minutes due to this issue.

You might have a problem with the Samsung Dishwasher ECS Sensor or the Drain Sensor instead of the drain. Sensors deteriorate over time and may become dirty or fail as a result of wear and tear.

The sensors must therefore be found and cleaned as soon as possible. You will have to replace the device if that does not work.


Why is my Samsung dishwasher not draining and what can be done about it?

A problem has been reported with the Samsung dishwasher not draining at the end of the cycle due to a problem with the pump. The following six reasons might explain why that may be the case, as well as how you can remedy the situation.


It appears that the drain hose is clogged

Dirty and used dishwasher water flows into your plumbing system through the drain hose. In kitchens, dishwasher drain hoses are usually connected to sink drains or garbage disposal drains.

You’ll have trouble draining all the water from your Samsung dishwasher if there is something blocking the drain hose. 

The first possibility is that the hose is kinked and preventing water from flowing freely. When the dishwasher drains into the sink, that is what tends to happen.

Check to see if the drain of the appliance is not blocked with food bits if it shares a drain with the garbage disposal.

The best way to fix this is to inspect the dishwasher’s drain hose from top to bottom. The garbage disposal hose should be free of kinks and should not be clogged with food bits or other debris.

Lastly, check to see if the knockout plug has been removed, especially if the garbage disposal has just been installed. With the knockout plug, the dishwasher will not drain down the same drain as the sink.


There is a problem with the check valve

The dishwasher drain hose contains a check valve somewhere along its length. By installing this valve, the dishwasher is protected from water flowing in the wrong direction. Consequently, dirty water cannot backflow into the dishwasher.

If a check valve becomes faulty, it will either get stuck in the open position or in the closed position. Samsung dishwashers cannot drain water into household plumbing when they are stuck in the closed position.

You’ll see the relevant error codes if your dishwasher fails to drain as a result.

Check valves that are faulty can be cleaned and replaced by cleaning the valve and reinstalling it. You may be able to remove any dirt or debris that is causing the valve to stick closed by doing this.

You may want to replace the check valve with a new piece if the problem persists even after you clean it. In addition to lasting a long time, check valves can be purchased at a reasonable price.


The fine filter in the drain is clogged

There’s a drain filter inside your Samsung dishwasher. Drain hoses remove water from appliance bottoms as it accumulates there.

Drain filters are designed to catch solid food particles once they have been removed from your dishes. As a result, no water will be recirculated back into your dishwasher, and your drain hose will not be clogged.

The drain filter will become saturated with food waste over time. The more waste accumulates in the appliance, the harder it will be for the water to drain. The buildup on the filter will prevent water from draining from the dishwasher if the filter is not cleaned.

The Samsung dishwasher will then display the relevant error codes, alerting you to the draining issue.

Thankfully, this is a very straightforward issue to fix. Your dishwasher’s drain filter needs to be removed and thoroughly cleaned.

As much waste as possible should be removed before removing the filter. It is important to remove the filter this way in order to keep the waste from clogging the rest of the drain system.

The filter should be reinstalled as soon as it has been cleaned.


There is a problem with the drain pump

Your Samsung dishwasher is equipped with a drain pump which is located at the bottom. A water impeller is used in this electrical component to remove all of the used water from the dishwasher using an impeller. Consequently, the water is forced through the drain hose towards the plumbing system.


Faulty drain pumps can cause draining problems.

Electrical and mechanical failures are both possible with this component.

As an example, the pump could burn out over time from excessive wear and tear, or it could short out due to an electrical fault. An impeller can be jammed mechanically by a foreign object. In the event that the impeller becomes stuck, the water within the tank will not be able to drain.


Check the drain pump for blockages before troubleshooting it and fixing it. The drain pump should be cleaned and any foreign objects or food buildups should be removed.

If it has an electrical fault, you can troubleshoot it using a multimeter. The pump will need to be replaced when it needs to be replaced.


There was a problem with the drain solenoid

The drain solenoid is used in some older Samsung dishwashers. Essentially, it controls the flow of water out of the appliance by opening and closing an electrical component.

In the event that the dishwasher gets stuck in a closed position, a faulty solenoid will prevent it from draining. The appliance displays the relevant error codes as a result of no water draining out.

The drain solenoid may need to be replaced in this case to fix the problem. Additionally, the solenoid is located near the drain pump and drain hose on the bottom of the dishwasher.


An issue has occurred with the water inlet assembly of the Samsung dishwasher.

On its way to the drain hose on your Samsung dishwasher, water flows through the water inlet assembly.

The water inlet assembly is likely to be the cause of your dishwasher draining problem, if you have ruled out all other possibilities. 

A water inlet assembly sits between the water inlet assembly and the drain hose as water travels through it. However, it is natural for food bits or other particles to accumulate at the water inlet assembly, resulting in blockages.

As this blockage continues to worsen, no water will be able to pass through until it is completely resolved. Moreover, you’ll see the relevant error codes flashing on your Samsung dishwasher at that point.

The blockage needs to be cleared to fix this. On the dishwasher, remove the panel covering the water inlet assembly on the left. As you remove the assembly, you’ll see several gray hoses attached. Remove them as well.

You can use your fingers or a small brush to remove any blockages once the hoses are removed.


What Is The Best Way To Force Drain A Samsung Dishwasher?

Press and hold the CANCEL or START button (depending on your dishwasher model) for 3 seconds to force drain the dishwasher. There is a possibility that your drain pump or hose is clogged or jammed if not all water is drained out after this drain reset.


Samsung Dishwasher Drain Pump Check: How Do You Do It?

  • The lower rack should be pulled out.

  • Cylindrical microfilters should be removed.

  • The filter should be wiped clean of any moisture or water.

  • Drain-pump covers can be removed by pushing their handles up and pulling them out.

  • Spin the impeller with your finger to make sure it’s working properly. Make sure the pump is clean by removing any dirt.

  • The drain pump cover should be placed back in place, and then pressed down until it clicks.


Unclogging a Samsung dishwasher drain hose: What Is The Best Way?

Drain hoses can be unclogged by removing them from sinks and using a screwdriver to remove any blockages from the hoses, tailpieces, or food waste disposers.


If a drain error light appears, but no drain issue exists, what should be done?

When you use your Samsung dishwasher DW80F600UTS, you may receive a “Drain error” message. Does it run and drain simultaneously for all five Cs, SCs, 5Es, SEs, or NDs?

Would it be better if the dishwasher stopped every nine minutes?

The Samsung Dishwasher ECS Sensor or Drain Sensor might be faulty.

It is certain that this sensor will get dirty over time, and the only way to fix it is to clean it or replace it.
