5 Common Samsung Dishwasher Problems

Samsung dishwashers, although a leading brand, are prone to their own set of specific problems. Follow this guide to understand and repair the 5 most common Samsung dishwasher problems.

The 5 most common Samsung dishwasher problems are: not cleaning dishes properly, not draining water, no power or problems with the touch pad, dishwasher not starting or, finally, the dishwasher not drying dishes. Read on.

Samsung Dishwasher Problems

Here are the 5 most common Samsung dishwasher problems:

1.     Samsung Dishwasher Not Cleaning Dishes

One common problem associated with Samsung dishwashers (or any brand) is that they don’t properly clean the dishes, especially those on the top shelf.

The first thing to check is the spray arms.

Spray Arms

Occasionally, debris and food from the dishes can fall into the little spray holes, which causes them to project the water less forcefully.

If you see any debris, clean it out. To prevent this from occurring, rinse your dishes before loading them in the washer.

Once you have checked the spray hose, you should look at the filter assembly as well.

Filter Assembly

Occasionally, food debris and waste can get caught under the filter assembly, causing the dishwasher to not clean as properly as it normally does.

The reason for this is that the food prevents the dishwasher from creating the proper water pressure for cleaning your dishes.

Begin by removing the lower spray head. Use a screwdriver to pry off the water tubes. Remove the screws that are holding the filter assembly in place.

Lift the assembly up and out once the screws have all been removed. Next, remove the impeller by unscrewing the connecting screw. Turn it clockwise to remove it, not counterclockwise.

With the impeller removed, pick up any debris you see, using your hand or turkey baster. After all the debris is removed, reassemble the dishwasher.

2.     Samsung Dishwasher Not Draining

A common problem of Samsung dishwashers is that they do not drain properly.

Normally, your dishwasher will fail to drain properly due to food buildup and debris that isn’t rinsed off beforehand.

Similarly, normal wear and tear can cause other parts related to the dishwasher’s draining to fail as well.

There are six main reasons that your dishwasher may not be draining properly.

The drain hose, check valve, drain filter, drain pump, drain solenoid, and water inlet assembly are all possible reasons as to why the dishwasher is not draining properly.

  • Drain Hose: The hose can become kinked. Manually remove any kinks. Drain hoses can also become clogged with food. Clear any waste.
  • Check Valve: Water won’t drain properly if the check valve is in the closed position or damaged. Clean the valve first. If it does not fix the problem, replace the valve.
  • Drain Filter: Remove drain filter to see if any debris is in the way.
  • Drain Pump: Wipe away any moisture or water from the filter. Remove the drain pump covering. Check the impeller. See if it’s in good condition by spinning it with your finger. Remove any water and grime on the pump. Additionally, use a multimeter test to see continuity reading.

3.     No Power/Touchpad Not Responding

Many Samsung dishwasher owners find that their dishwasher either has no power, or that the touch pad (control panel) does not respond.

This happens due to the main control board or touch pad interface board GLITCH.

Get Control Board Here

When this happens, you may find that unplugging the unit helps for a while, but the problem might reoccur after you have begun using it again.

Samsung recommends reseting the circuit breaker of your home.

This is a good first step to make sure that there isn’t a tripped breaker.

With that being said, many faulty models are not due to a tripped breaker.

Get Touchpad Here

Instead, many people have found that the control panel is at fault for this mistake and that it has nothing to do with the user.

Instead, the Samsung control panels go bad faster than other models, causing the dishwasher to fail to start or for the touchpad to not respond.

If the control panel is at fault, which it probably is for this issue, you will simply need to purchase a new control panel and install it in place of the old one.

To install this part, begin by unplugging the dishwasher before use and maintenance.

Then, remove the inner door panel from the outer door panel. Do not fully remove the door mounting screws.

Now, take out the panel and disconnect it from the wiring, but note the direction of the wiring.

Connect the new panel in the place. Reconnect the wiring to the proper terminals. Secure the wires in the holders and reassemble the door.

4.     Samsung Dishwasher Won’t Start

One of the most common problems with the Samsung dishwasher is that the appliance won’t start.

There are a number of reasons that a dishwasher won’t start. Here are the two most common:

  • PE Error Code: If your dishwasher is showing this error code, then your dishwasher has an issue with the power control board.
    As a result, you will need to replace the power control board. You will access the power control board through the lower access panels.
    Remove the housing, disconnect the wires, and replace the faulty control board with a new one. Reassemble.
  • Issue With The Locking Mechanism: Your dishwasher will not start if the locking mechanism is faulty.
    Many Samsung dishwashers fail to start because of a faulty locking mechanism. If your dishwasher won’t start and there’s no errors reading, consider installing a new switch door latch.
    Begin by removing the inner door panel from the outer door panel. Separate the panels and slide out the old latch.
    Disconnect the wires. Place the new latch on the mounting screws and connect the wires. Reassemble door.

5.     Samsung Dishwasher Not Drying Dishes

Finally, the last common problem with Samsung dishwashers is that the appliance doesn’t dry the dishes properly.

The parts that help to dry dishes are the heating circuit and the vent case assembly.

Get Vent Assembly Here

For many Samsung dishwasher users, the vent case assembly is what causes the appliance to improperly dry the dishes, not the heating circuit.

The vent case assembly is what lets the steam out of the dishwasher. It includes a fan and a vent.

If this assembly does not work properly, the steam stays inside the dishwasher, making your dishes seem very damp even after the dry cycle.

Begin by removing the upper and lower racks of the dishwasher. Then, separate the inner panel from the outer panel by removing the screws.

Remove the front panel. Drop the console panel and set the latch assembly to the side.  Remove the wiring from the console panel.

Next, disconnect the vent case assembly wiring and peel back the tape on the wiring.

Free the vent tube and open the vent case assembly. Twist the lid covering of the assembly counterclockwise to gain access to the vent assembly from the front.

Now, install a new vent assembly through the front of the door. Reassemble the dishwasher.

  1. I have a 2 year old Samsung dishwasher and I love it. Works great except the last few weeks when I load, or unload it … a few minutes later I get this sewer/sulphur smell. I have an ac vent on the floor right in front of it. It takes 2 minutes for the smell to get to all the vents. No smell in the dishwasher and I’m just guessing it has something to do with the dishwasher. It’s very clean … I run vinegar in it everynight as a rinse aid. Filters clean. Any ideas???

  2. I have model DW80M2020US dishwasher that came with my newly built house in 2017. I haven’t seen this complaint but the wheels on my bottom drawer has rust on them & came off the drawer. There is rust on the bottom of dishwasher in the corner.

  3. Samsung DW80F800 Series about 6 yrs old. Lately I find a puddle of water in front of the door after the cycle is complete. Started small, getting bigger. Otherwise, it seems to run just fine, dishes are clean and dry. Where should I look for the problem?

    • 1. Door seals worn out ( also check bottom seal inside the dishwasher)
      2. Make sure bottom spray arm is not clogged or cracked. otherwise, water will be not evenly spraying inside
      3. Remove kick-plate panel and check underneath the dishwasher

  4. The Samsung dishwasher came with the house we bought, but doesn’t seem too old. When we start a cycle it starts up, makes some noise, then stops. The “Smart Auto” begins to flash. There is no water spraying when I open door. Thoughts?

  5. have samsung dishwasher with power into the control board but no power coming out to the door switch. Is the control board bad or something else?

    • It can be either the main control board or UI (user interface) board.
      I had this situation before, but one time this problem was fixed by replacing the main control board and the second time, main control board didn’t fix the problem.
      Try to reset power first. If the problem will come back again, replace the main control board.
      Also, clean ribbon cable connection between UI and main board.

  6. I have a Samsung washer, not sure how old because it came with the house I bought. It will start up fine and the dishes are wet at the end of the cycle so I’m thinking water is working.. but it won’t actually go through a wash cycle- it will act like it’s trying to for a minute then stop and signal the tune like it’s finished but it hasn’t even been running for more than 5 minutes. The “Delicate” light blinks after but it’s always done that, even when it worked properly. Any ideas why it won’t go through a wash cycle?

  7. I just got my hand on a used Samsung Dishwasher DW80K5050UW. I not sure about the proper sequence of a wash cycle. When I start any cycle the Drain pump kicks in a few times for a short period (normal) then it fill water. After the fill it look like the circulation pump try to turn ON but it’s only lasting half a second and it repeat this several time (7 to 8) to finally start and complete the cycle. Is this normal or it a sign that the pump and or control is slowly dying ?

  8. I have a Samsung dishwasher dw80n3030us. It gets part way through the cycle and stop and flashes the heavy and 60 second express wash lights. It continues to drain out and then stops. It’s barely a 1 year old.

  9. Samsung DMS300TR or DW-FN310T Approximately 6 years old.
    Problem is fresh water from the tap supply enters the machine shortly AFTER a program is completed
    Water overflows and then wets the floor

  10. Hopefully I might get some help on this..
    My Samsung Dishwasher gets “stuck” in a cycle..
    so it goes through the motions of its cycles but at some point it stops counting down and eventually ( like an hour later or so) it presents the HE error.

    On the quick 35 minute cycle it gets stuck on 27 minutes before doing what I mentioned.

    Is it truly a heater issue or it this something with the CPU.. It does heat up the water so….

  11. Dishwasher starts running like normal but after a couple of minutes it just stops and then the soap door opened. There is about 1/2 inch of water in the bottom. It is heating up cause when I open the door – there is steam. No error codes show up and not running.

  12. Samsung Model DW80K7050US drain is clean and it will go through it’s cycles but it takes 3 days. When I turn it on, it will run, then stop and just keep clicking and blinking the current part of the cycle with water in the bottom. If I wait until the next day, I can turn it on and then it will drain and run the wash cycle and stop again with water in the bottom and just click and blink. I turn it off and the 3rd day I can turn it on and it drains and does a rinse cycle but won’t drain that cycle, just blinks with 1 minute left and doesn’t even try to drain. Each time it stops right before it should turn the drain on and just blinks the current part of the cycle and time left and you can hear it click. It never even tries to turn the pump on until I let it stay off for several hours. Is it a control board issue? It drains good after it sits for several hours.

      • Sorry, i can’t identify your problem for 100%, but seems like it is not draining all the time properly. Am i right?

      • Correct, it doesn’t drain when it’s time. It doesn’t even turn the pump on to try. But if I turn it off and unplug it for a few hours and turn it back on for a rinse or cancel and drain it will do it fine. It seems to me like a communication problem to the drain pump but I don’t know?

  13. Hi! I have the Samsung stormwash dw80k5050us and when plugged in the fan is running continously but the control panel won’t turn on.

    I have tried replacing the control panel and the lock but that did nothing! Any ideas??

    • If you already to replaced control panel (i assume you are talking about a touchpad user interface panel) and it didnt fix the problem, next thing is to replace main control board. Cause, fan is getting power from the main control board, but not from the control panel

  14. Samsung model DW80J3020US had it less than 5 years. Diligent in taking it apart and cleaning it out. The check valve is good and intact. Pump works. Drain hose is clean and not kinked. Checked the water wall and it was a little dirty but not plugged. It just stopped draining. Wondering which sensor is causing the issue.

  15. Unit does not flash error codes. The dishwasher will fill with water but drains the water before the initial wash cycle. Some suggest the “Case Sensor Assembly Case” needs to be replaced? Help?

  16. I have a Samsung Dishwasher that is not easing the dishes. There is a buzzing noise coming from where the pump is. Is the pump bad ?

  17. Hi I have model dw80n3030us and it powers up, but doesn’t fill with water, and it came with new home I just purchased, it’s brand new!!! I reset the breaker but didn’t do anything, what can be the issue?

      • I did. The water valve under the sink is on and also valve underneath in the basement is on so Idn what the problem is?

      • AS long is it a brand new dishwasher, I still think, something wrong with the water supply. Turn water off under the sink and Disconnect hose from the dishwasher. Than get a bucket and turn water ON to see if the water pressure strong enough
