For a Samsung dishwasher to work effectively, clean water must flow in, and dirty water must be able to drain out without any problems. However, there are times when the appliance will fail to drain the water inside.

If your Samsung dishwasher isn’t draining, it will display error codes indicating a draining problem. The problem could be caused by clogs in the drain hose, a fine filter, drain pump, or water inlet assembly. Besides that, parts like the check valve and drain solenoid could also fail to open, thereby preventing any water from flowing out of the dishwasher.

Let’s take a closer look at why your Samsung dishwasher isn’t draining and what you can do to fix it.


Before performing any repairs on your Samsung dishwasher, always disconnect the appliance from its power supply. Doing this will eliminate the danger of electrocution and reduce any injury risk.

Working with dishwashers also involves dealing with water. So, shut off the water supply to the appliance and prepare towels to wipe up any spills.

Lastly, be sure to keep your user manual and any available technical sheet nearby. These documents are helpful references to help with locating and identifying essential components.

“No Drain” Error Codes

Some Samsung dishwasher models will display error codes to inform you of draining problems. Among the codes that you might come across include:

  • 5C
  • SC
  • 5E
  • SE
  • OC or 0C
  • DELICATE light flashing

To know which error codes apply to your Samsung dishwasher model, refer to the user manual. There, you’ll find standard error codes and what they mean.

False Error Codes

In some cases, you might also experience false error codes. That’s when the dishwasher displays any of the error codes listed above, suggesting a draining issue, even though the appliance continues to function and drain normally.

While this issue is happening, the dishwasher may also stop mid-cycle after 9 minutes for no apparent reason.

If that’s the case, then the problem might not be with the drain, but the Drain Sensor or Samsung Dishwasher ECS Sensor instead. Unfortunately, over time, these sensors experience wear and tear and might get dirty or fail.

So, you’ll need to locate and clean these sensors. If that doesn’t work, you’ll need to replace it entirely.

Why Samsung Dishwasher Is Not Draining?

Suppose your Samsung dishwasher is not draining at the end of the cycle. Here are six reasons why that might be the case and what you can do about it.

Drain Hose Clogged

What it is: The drain hose allows all of the dirty and used water from your dishwasher to flow out into your household plumbing. Since the dishwasher is typically located in the kitchen, the drain hose is connected to the same drain as the sink, or it might share one with the garbage disposal.

How it fails: Your Samsung dishwasher will have a challenging time draining all of the water out if there’s something preventing water from flowing through the drain hose. 

Firstly, the hose might be kinked and therefore restricting the flow of water. That tends to happen when the dishwasher shares a drain with the sink.

However, if the appliance shares the same drain as the garbage disposal, check to ensure that the drain isn’t clogged with food bits or other junk.

How to fix: To fix this, start by inspecting the entire length of the dishwasher’s drain hose. Make sure that no part of the hose is kinked. Then, remove the hose to check that there are no blockages, such as a buildup of food bits or other items coming from the garbage disposal.

Lastly, check to ensure that you’ve removed the knockout plug, especially if you’ve just installed new garbage disposal. The knockout plug will prevent the dishwasher from draining down the same drain.

Check Valve Worn Out

What it is: At some point along the length of the dishwasher drain hose, you’ll find a check valve. This valve ensures that water only flows one way, i.e. away from the dishwasher. In doing so, it prevents any dirty water from back flowing into the dishwasher instead.

How it fails: When a check valve becomes faulty, it will get stuck either in the open or closed position. When it gets stuck in the closed position, none of the water being drained out of your Samsung dishwasher will be able to flow out into your household plumbing.

That will result in your dishwasher failing to drain and displaying the relevant error codes.

How to fix: When faced with a faulty check valve, you can start by cleaning the valve and putting it back. That might clean away any dirt or debris that’s causing the valve to be stuck in the closed position.

However, if the check valve still causes problems even after you’ve cleaned it, then you’re better off replacing it with a new part. Check valves are inexpensive, and a new one will last you for a long time to come.

Drain Fine Filter Clogged

What it is: Inside your Samsung dishwasher, there’s a drain filter. This part is located towards the bottom of the appliance, where water pools before it’s removed through the drain hose.

The purpose of the drain filter is to catch any of the solid food bits once they’ve been washed off of your dishes. That way, none of it will be recirculated back throughout the dishwasher, and none of it will clog up the drain hose or your household plumbing.

Ge dishwasher fine filter clogged

How it fails: Over time, the drain filter will get saturated with food waste. The more waste builds up, the harder it will be for water to drain out of the appliance. If the filter is not cleaned and the buildup becomes worse, the dishwasher will fail to drain any water.

At that point, your Samsung dishwasher will begin displaying the relevant error codes, bringing your attention to the draining problem.

How to fix: Thankfully, fixing this is very straightforward. What you’ll need to do is remove the drain filter from the bottom of your dishwasher and clean it thoroughly.

Before you remove the filter, first remove as much of the waste buildup as possible. That will prevent the waste from clogging other parts of the drain system as you take out the filter.

Once the filter is cleaned, reinstall it the same way as before.

Drain Pump Failed

What it is: At the bottom of your Samsung dishwasher is a drain pump. This electrical component forces all of the used water out of the dishwasher using an impeller. In doing so, it pushes the water through the drain hose towards your household plumbing.

How it fails: Draining problems can be caused by a faulty drain pump. This component can fail in two ways: electrically and mechanically.

For instance, the pump could short out due to an electrical fault, or it could burn out from excessive wear and tear over the years. Mechanically, a foreign object could jam the impeller. A stuck impeller will not be able to drain the water inside.

How to fix: To troubleshoot and fix the drain pump, first check it for any blockages. Clean the drain pump and remove any foreign objects or buildups of food there.

A multimeter will help you troubleshoot it for an electrical fault. If there is one, you’ll need to replace the pump with a new one.

Drain Solenoid Failed

What it is: Some older Samsung dishwashers rely on a drain solenoid. That is an electrical component that opens and closes to control the draining of water out of the appliance.

How it fails: A faulty solenoid will prevent the dishwasher from draining if it gets stuck in a closed position. As a result, no water will drain out, and the appliance will display the relevant error codes.

How to fix: Fixing this will require a new drain solenoid replacement. You’ll find the solenoid on the bottom of the dishwasher, near the other draining components (i.e. near the drain pump and drain hose).

Water Inlet Assembly Clogged

What it is: When draining your Samsung dishwasher, the water will flow through the water inlet assembly on the way to the drain hose and out of the appliance.

How it fails: Assuming you’ve ruled out all the other possibilities, then it’s likely that your dishwasher draining problem is happening at the water inlet assembly. 

Remember: water flows through the water inlet assembly on its way to the drain hose and out of the machine. So, naturally, blockages can occur at the water inlet assembly, consisting of food bits or other particles.

The longer this blockage is left unresolved, the more severe it will become until no water can flow through. That’s when your Samsung dishwasher will begin flashing the relevant error codes.

How to fix: To fix this, you’ll need to clear the blockage. First, remove the left-hand panel on the dishwasher that covers the water inlet assembly. Next, you’ll see several grey hoses attached to the assembly, which you’ll want to remove as well.

With the hoses removed, you’ll be able to clean out any blockages using your fingers or a small brush.

How To Force Drain Samsung Dishwasher?

In order to force drain dishwasher, press and hold CANCEL or START button (depends on the model you have) for 3 seconds. If after this drain reset not all water was drained out, you most likely have a jammed drain pump or clogged drain hose.

How To Check The Drain Pump Of Samsung

  • Pull the lower rack out.
  • Remove the cylindrical microfilter.
  • Wipe any moisture or water from the filter.
  • Remove the drain-pump cover by pushing its handle in the up direction and pulling it out.
  • Check the impeller to make sure its in good condition and try to spin the impeller by finger. Then, remove any dirt from the pump.
  • Put the drain-pump cover back into place, and then press down until you hear a clicking sound.

How To unclog the drain hose on Samsung dishwasher?

In order to unclog the drain hose, you need to disconnect a hose from the sink and use a screwdriver to remove any blockage from the hose or from the sink drain tailpiece or food waste disposer, depending on your setup.

What To Do If Drain Error Light Shows Up, But No Drain Issue?

Do you have Samsung dishwasher DW80F600UTS or a similar model, that has a “Drain error” message, which is 5C, SC, 5E, SE or ND , sometimes during mid-cycle, but at the same time, it might running and draining absolutely fine?

Or maybe the dishwasher stops every 9 minutes?

You might have an issue with Drain Sensor or Samsung Dishwasher ECS Sensor.

This sensor over time gets dirty and all that you can do is to clean it or replace it with a new one. You can get it here

  1. Thanks for the blog .. really useful. We had a “price sticker” (from a new cup) stuck in the hose connecting the drain pump to the water panel. It was not coming out by blowing as the hose has a one way stopper. We had to pry it out using a wire.

  2. Long time listener, first time caller, yatta yatta …. I’d also like to say thanks for this page as it helped to eventually solve my issues with my Samsung DW80R9950US dishwasher. However, my issue was caused by the dishwasher itself …. Our model of dishwasher comes with a third tier “silverware” rack that has hundreds of plastic tines to help to separate the utensils. We noticed that many of these tines started to break off from the rack itself, and we would find them at the bottom of the dishwasher. We contacted Samsung and they sent out a new replacement rack (which was the same materials) and we thought nothing of it. However, we started getting the “5C” errors, and after MANY attempts and chasing the hose from one end to the other, I realized that a few of these tines had found a way to bypass the filtering system completely, and were stuck in the “drain hose redirect thingy” at the top of the kitchen sink. Once I removed the top plug, I was able to force the broken tines back thru the line to collect them and the line was free again. Just wanted to mention that if you are having tines break off from your silverware rack, you may also want to check the drain lines to make sure you don’t have restrictions in it.

  3. Hello,

    We have a Samsung dishwasher, model #DW80R9950US.
    We get a SC error code. We cleaned the machine. We called in a repair guy. There are no clogs, kinks of any kind, and the machine drains. We do, however, have a water pressure problem, which we are trying to fix. Would low water pressure trigger the SC error code?

    Thank you,

    • I dont think that low water pressure issue related to “NO DRAIN”. Another thing… how quickly it drains? If nothing is clogged it should drain in 15-20 seconds. If it’s partially clogged it might drain ok, but will not let’s say after a couple of loads and 5C error code will show up. How long your draining?

      • Thank you for your reply, Eugene. Yes, I would say it doesn’t take too long to drain. Now the repair guy has ordered a new pump, but I’m worried he’s on a goose chase.

  4. j’ai un problème avec mon lave vaisselle j’ai les lumière smart auto et heavy qui clignote toujour j’ai de jas changer la plaque blanche dans le coté et aussi la ompe de vidange et ces toujour pareille je ces pue quoi faire ces un samsung

  5. Ive followed all of the steps above the pump wont remove the water, and the drain cover is missing, model dw80k5050, also it appears as if its pushing fluid inside the machine rather then removing, is the pump by directional if i hooked up the wires wrong will it spin backwards? please help on this part above

    • pump running on AC power, so it doesn’t matter how you connect wires it will be spinning in right direction

  6. I have a Samsung dishwasher, that us flashing “LC”, and the drain is continuously coming on. I know LC means water leak or moisture. I took out the strainer and cleaned it. The drain at the bottom, under the strainer, will come on, empty, cut off then a small bit of water comes back in from the drain opening, then it kicks on again.

    Suggestions? Any ideas?

    Many thanks.

    • What the model number of your dishwasher? Check float switch inside the dishwasher. If it’s stuck in the Upper position and will trigger LC error code. Cause float switch sits in series with the flood switch. if one of them disengages, it will trigger LC error code

  7. I have samsung dw80f600uts. Found water leaking from front of dishwasher. Water will partially drain out when I drain manually (holding start for 3 seconds) so motor is working, but I have to do it like 3-4 times to fully drain all the water. Tried a new cycle, and I can see it draining out the hose but 20mins in it shuts down, and flashes Smart-Auto and Heavy. I checked for hose blockages, cleaned the filter, checked for motor blockages. What am I missing?

    • There is a partial clog in the drain line for sure. Did you check the drain hose where it’s connected to the sink? Did you check hoses on the left side of the dishwasher (see the picture in the article)?

  8. I have tried every one of the six. The only thing I havent done is replace the ECS. I took it out, cleaned it, put it back in. Still does drain or complete final cycle. What I do notice is that when it went into drain cycle, I would always hear a prominent click, and the drain pump come on. I do not hear that prominent click, and do not hear the drain pump come on.

  9. Hi guys, so The water does not drain from my dishwasher. I’ve only been using it for one year but just ran out of warranty. I replaced the check valve. I cleaned the filters and the entire machine thoroughly.I also checked the hose connected to the sink and everything is clean. I was able to do this while the machine was open and I just unscrewed everything that I had access to at the bottom of the machine. I’m nervous about taking the machine out of its space and moving it upside down because that has electrical connections and other things that I know nothing about. I saw a couple of videos online but they are not specific enough for me and they assume that the person knows about electrical connections and water pipes connections and I do not. If you know of any online videos that Can explain it to me like I’m a five-year-old I would really appreciate it. And by the way I did have one plumber come in and check it out and tell him if he thinks it’s the pump and I should just buy a new machine. Since the machine is so new I thought I would buy the pump and maybe hire somebody to put it in but it turns out that’s too small of a job for a company to take on. Anyway.Many thanks

  10. Thanks for this page. It is incredibly helpful. My Samsung dishwasher is draining, but after several hours I will find water in the bottom of the unit. If we do not check it and manually and drain it by pressing two buttons, it will overflow eventually onto the ground. The drain line is clear and connects to our disposal. I am guessing since the drain motor works that it might be the check valve. Thoughts?

      • Thanks! I received the check valve for my SAMSUNG DMT300RFS/XAA. The part number is DD66-00019A. Unfortunately is was smaller than the one I removed from my machine. It appears to be the right part number. Should I order another one or move on to the water inlet assembly? Thanks for your help.

      • It is visibly smaller. I tried to paste a photo here but was unable. I ordered another one from another distributor. Just this morning, I found half an inch of water at the bottom. I perform the drain function and it all works well, but eventually the water left in the hose slowly returns.

  11. I am getting 5c error on DW80R9950US dishwasher. I checked the drain hose, filter, sump for clog. Most of the water drain and I can see water running thru the sink/garbage disposal but only a little of water ( 1/2″) left in the filter/sump pocket. What could be the problem ? Thank you.

  12. I am get 5C error on DW80R9950US. I checked the drain hose, the filter, the sump for clogged. It drained most of the water and I can see the water draining thru the garbage disposal/Sink but it still have just a little bit of water (1/2″) left in the filter/sump pocket. What could be the cause ? Thank you.

    • Partially restricted drain line. Check drain hose connected to the sink and also read the article again, pretty much everything covered there

  13. I have a “dC” code on a DW80K5050UG and Samsung cannot tell me what that is.
    It starts fine by draining which I can see is clear water. It sounds like it then fills with water (which it does b/cit also drains it when I cancel) It then clicks a few times originating from what seems like the panel below the door- but never starts the wash.


  15. I have a model DW80R5060US and I get an OC error code but it all seems to be draining properly. Filters are clean, there’s no clog in the sink drain, no kink in the drain hose, pulls in water no problem…not sure what I should be looking for next.

  16. Hi there,

    I have the 5c error on my Samsung DW80K5050UG. It isn’t filling. I suspect there is a blockage. Is there a filter on the water inlet or a place to verify water supply?
