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. Model DW80R9950UG. Worse dishwasher ever. I have tried loading it as in the illustration and it still does not get the dishes clean. Especially on the top. Not worth the cost. The only positive is that it is quite.

    We also purchased a refrigerator. Again, not worth the cost; even though it was on sale. The icemaker is horribly slow. We have to buy bagged ice to have enough for the day.

    I am also one who will not buy Samsung products in the future.


  2. Have DW80K5050. Purchased 2017. Noise became unbearable. Repair man replaced motor. Good for 30 days and now noisy again (can hear it all over the house).
    Motors are from China; bearing seems bad.

  3. We are older and can’t take apart the nozzles and filter. I never had to do this with previous dishwashers (not Samsung). My top shelf dishes don’t get clean. I will never buy Samsung again.

  4. I have a samsung dw80j3020. When I start the dishwasher it first seemed to be working normally but I realized it wasn’t filling with water. The “Auto” light starts blinking but the machine appears to continue to run (without water). Any help would be much appreciated.

  5. Our Samsung dw80k7050 (4 years old) works perfectly. Except in the last month when it is running all the lights on the top go out intermittently then come back on. Is this a symptom of an impending failure. No error codes.

  6. This model WD80M2020US has a constant blinking light on the normal. The control panel does not respond to any other commands. What is the problem

  7. 1)- My Dishwasher Model is DW80M2020US/AA 00
    Year built 11-2018
    Serial # B03ZG8DKB17769A
    2)- Now the issue: it is biping and even when I disconnected from the Power on the wall for 10 minutes, still biping and not working!
    My guess is a big chunk of moeny is blocking thought and maybe the only way to fix it is to change the entire main electronic Panel! what would be your suggestion (s)?

    • Mine was beeping as well. Appears it was grease congestion inside the drain down below. I had my son remove the screens and my wife washed with soap and hot water in the sink, I took the credit for fixing it.

  8. We have a Samsung DW80K5050US. The bottom spray arm will not turn during the wash cycle. The upper arm does turn, therefore my top rack dishes are very clean, and vertical plates in the bottom rack clean good, but anything that is upside down on the bottom rack don’t even get touched. We have tore apart the whole sump assembly, cleaned out a lot of guck that was inside it, removed hair that was around the wash impeller, but the problem still remains. The spray arm is not clogged at all. What can be the problem?

    • I am having the same issues . We bought our two years ago and had problems from the start. Called service to fix problems, it still doesn’t spray right and causes the tablet to not drop In the two years we maybe only used it a dozen times. My wife hand washes the dishes before putting them in so we don’t know if it ever worked.

  9. The lower spray arm stops spinning because it hits the back wall of the unit, one end of the arm clears but the other end doesn’t, I measured the arm and found that one end is 1/2 inch longer can you advise me on how to correct this problem

  10. My Samsung dishwasher DW80R5061US is stuck on discharging the water. The pump will not stop running. I’m not seeing a float switch. How should I proceed?

  11. My Samsung dishwasher (DW80T5040US) goes through cycle then quits at end of cycle. Error code E5. Does not drain. Mind you, as cycling process I hear draining constantly. Then at end of cycle it stops and doesn’t do final drain.. error code E5. So this out rules plugged drain. Not understanding the E5 error. Anyone have a solution?

    • I recommend you double-check, water inlet assembly (on the left side of the dishwasher) for any clogs in there. From my experience, this is one of the common problems when you have an intermittent drain.

  12. Hi. I have a samsung dw80j7550ug and it seems to not be heating the water. Any suggestions? I was told by an appliance repairman that they no longer make the circulation pump for this, so I’ll have to replace the whole dishwasher. Could it be something else causing the issue?
