Read on to learn about the 5 most common Samsung dishwasher problems and how to fix them.

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 is that they don’t properly clean the dishes, especially those on the top rail.

The first thing to check is the 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.

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 from 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 touchpad does not respond.

Sometimes this happens due to the main control board or touchpad interface board glitch.

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. 

Final Thoughts

We hope that this article has made the process of identifying and fixing your Samsung dishwasher easier and less stressful. Always remember to be safe when fixing any appliance, including your dishwasher, by unplugging it from the power outlet and disconnecting the water source before maintenance.

  1. My Samsung dishwasher started on its own. I sounds liked the water removal pump is running. Push the power button and it shuts off for a couple seconds and restarts again the same way. No other buttons work. Only way to shut it off it throw the breaker or unplug it. Any ideas. Thanks

  2. We have Samsung dishwasher for one year. The wood board under its door keeps on popping out. I put back but after few uses when we open dishwasher’s door it pushes out the board again and again. Any advice on how to fix this problem?

  3. Hi, I am trying to seek an answer for my Samsung dishwasher DW80M9960UG, bought say 4 years ago. The problem is when I close the door I can hear the bottom water deflector moves back and forth about two times and starts giving beeping sound every 30 seconds. I notice nothing wrong really. I reset the washer by unplugging, no help. No error codes. Can I draw on someone’s intelligence here what is the user intervention needed here? I am new to this site, hope someone will see this and can help. During the pandemic it is hard to find someone to repair on site! Thank you millions.

  4. dmt 300 rfs dishwasher – normal and heavy cycles are running only 1 hour instead of the 2+. Some soap remaining in dispenser. Dishes not thoroughly clean.

    two blinking lights – heavy/delicate

    Reply
    • HEAVY/DELICATE – this error related to the problem with the heating element. Either element is burnt out or there is a problem with the control board. Check resistance of the heating element, if it reads infinite, the element is burnt out.

  8. Samsung dishwasher model DW80M2020Us. It cleaned the last cycle but when I opened the door to unload the dishes. I noticed that the normal cycle is flashing, turning the power off doesn’t resolve the problem it just turns right back on and makes a humming noise. I turn the power off at the break I wait 5 minutes I then turn it back on and it just continues the noise. This light code issue of the normal cycle blinking happened awhile back there was a lot of water still in the tub. We managed to get the water out, my wife figured out how to fix that issue when she googled it. I believe it still might the same issue that it thinks that there is still water in the tub or underneath any thoughts

    • Hi Alan. Flashing NORMAL CYCLE light means there is leak. You need to pull dishwasher out and remove left metal cover on the side. Maybe you will be able to figure where leak coming from. Then you need to lay dishwasher on its back or on the right side, be prepare to catch some water. Remove bottom cover, underneath dishwasher.. You will see leak sensor. Wipe that area, to remove residual water and assemble it back.

  10. Hi Eugene
    My dishwasher stops mid cycle with an error code F5. Some websites suggest it is due to clogged spray arms but I checked and cleaned them and still the issue persists. The pump seems to be turning fine (removed cover and checked during operation). Any thoughts?

  11. My Samsung dishwasher is just over 2years old and it is not allowing water thru, checked filter at inlet valve and water pressure perfect.

    Reply
    • The best way to check is inlet valve is getting power or not, is to start a new cycle of the dishwasher and check if power coming to the inlet valve using multimeter. Also, Did you try to reset power breaker?

  12. Damaging dishwasher flashing code “heavy” we checks and there are no leaks and it also comes on when the dishwasher is powered off?

    Reply
    • If you see no leaks, you should remove the sensor and clean it anyway. I am sure you will find a small pile of water under the sensor. Also, check float switch to make sure nothing got stuck between float and dishwasher. This float activates drain pump and it runs constantly,

  13. I have a Samsung dishwasher. Recently dishwasher starts and then stops after 2-3min. No alerts/lights come on, timer continues but cycle does not continue. No rinsing/washing of dishes, nothing happens
    What could the problem be.

  14. Dishwasher stopped mid cycle. Managed to get it to drain out water by resetting circuit breaker. Now, dishwasher won’t start. The display showing “time remaining” blinks either the full cycle time (3:14) or the canceled time (1 min). Tried resetting circuit breaker, checked hoses (supply and drain). Dishwasher does not display an error code.
    Model: DW80J7550UG-004 We have had constant problems since purchase.

  16. Hello, i have samsung dishwasher, was not happy with it from the day one. it has been 5 years now, when i am setting a normal or heavy setting, it stops after sometime and the two lights from normal and smart auto keeps flickering. Today i put it on delicates, and it worked fine. What could be the problem

    Reply
    • Blinking lights Normal and Auto – high temperature error. Check your thermistor (temp sensor) for having gunk around the sensor or calcium build-up and clean it. If it will not help get a new temp sensor.
