LG dishwasher NE error code – 3 things to check

An LG dishwasher NE error code is an indication that there is a problem with the diverter (vario) motor in your dishwasher.

Micro Switch Error: LG dishwasher NE error code

The NE error code refers to the micro switch in your dishwasher. This switch is responsible for reporting the motor’s position in the dishwasher to the board.

When the micro switch signal is failing to reach the main board, you’ll see the NE error code pop up. If the micro switches are defective, it is likely you will need to replace them. This will allow the signals to properly indicate to the control board.

Diverter Motor Failure: Steps to Determine Repair/Replacement

The diverter motor (vario motor) controls the flow of water to the spray arms. To check the diverter motor for failure, you’ll undergo a series of steps to determine what the issues are.

Check Loose Wires

The first thing you’ll want to do with this error is to turn off your dishwasher. You’ll then:

  • Check the wires and harnesses to ensure everything is in the proper position/location
  • Check all connections on the diverter motor and diverter position switch (if they’re misaligned, the solution might be simply realigning and moving wires to the correct location)
  • Reconnect any loose wires

Diverter Motor Check

If you determine the wiring connections are okay, you’ll go onto the next step, This requires unplugging the diverter motor wires and checking for checking motor resistance using a multimeter.

The reading should be about 4000 ohms of resistance. If the ohm measure is infinite, you will replace the diverter motor.

If the diverter motor is okay, you’ll then run a check on the diverter motor switch.

Diverter Motor Switch Check

Once you’ve obtained the correct ohm reading on your dishwasher, you’ll next check the diverter motor switch.

To check the reading on the switch with the multimeter, you’ll need

  • Measure resistance through the diverter position switch
  • The switch plunger should be pushed in and the switch plunger should be extended during this test
  • Your meter should measure infinite resistance with the switch plunger in one position
  • When the switch plunger is in the opposite position, that reading should be 0 (or close to it)

If you are getting the same reading on the meter, regardless of which position the diverter motor switch is in, this indicates that there’s an error with the switch, and it needs to be replaced.

You’ll want to replace the diverter position switch, as it is not detecting the diverter’s position accurately while your dishwasher is on. This will cause the NE error code.

Diverter Motor Replacement

If you have to replace the diverter motor, you’ll first begin by turning off the water, and turning off the power on your dishwasher.

Remove the sound dampening pad below the dishwasher and disconnect the water supply line (some water will spill). Remove screws to access the junction box cover.

You’ll disconnect the wire nuts so you can disconnect the wiring.

Remove the strain relief nut. Disconnect the sink hose and feed it through your cabinet.

You can get a replacement diverter motor on Amazon for around $20-25. Be sure to check your model number. Click here.

Open the dishwasher door and remove mounting bracket screws. If you need to move the dishwasher, adjust the legs below it.

Pull the dishwasher away from the cabinet and open the door removing both upper/lower dish racks.

Close the door and tape the mounting brackets in place. Lay the dishwasher upside down for repair.

Remove the screws securing the bottom access plate and remove it. Once the access plate is free

  • Disconnect the diverter motor wire harness
  • Remove the screws holding the motor and remove the old motor
  • Prepare the new motor by transferring the cam from the old to the new motor
  • Insert the motor shaft into the diverter and secure the motor with the mounting screws
  • Connect the wire harness to your new motor, replace the bottom access plate, and screw it into place

At this point you can return the dishwasher to the upright position.

Place the racks back into the dishwasher, replace all screws which were removed, reconnect the water supply lines, and put the dishwasher back into its cabinet space.

As you can see, the diverter switch replacement is much easier than a motor replacement job. If you are unfamiliar with repairs, you might choose to call a repair technician to do this larger job in your home.

  1. Had LG technician replaced door switch and then the diverter motor and the micro switch. Dishwasher worked for 10 or so cleaning cycles. Now the nE error shows up again. This time though, unlike before where the code came up during any washing cycle, running just the Rinse doesn’t produce the code.

  2. hi Eugene,
    i have the ne error in my d1452lf LG dishwasher
    I saw ur video , but unfortunately i do not know how to remove the bottom axes “bottom cover” ???
    i can not see any screw !!

  4. Hi Eugene,
    My LG dish washer (Model- LDS5540ST) is not cleaning the upper portion while ashing and getting the Ne error.

    The Mocro switch is working fine and the Diverter motor is showing 3995 resistance. In this case what would be the issue ? which part is defective?

    Even though the Diverter Motor shows resistance of 3995, can it be still defective? How to confirm?

    Cold you please advise.

    • If you checked everything else and still have this issue, it will require some troubleshooting skills.
      Let’s say what i would do:
      1. Apply power 120V to the diverter motor and see if it will make a turn. I am not sure what motor resistance should be. But yours sounds right.
      2. Check the continuity of the switch and motor wires to the control board. Maybe some of them are broken.
      3. Check the sump area (inside the dishwasher, where the diverter shaft is coming out) and make sure nothing is jammed, thus the motor not able to make a turn.

  5. I have changed the diverter 3 times in the last 2 years and i am still getting the NE error code…what am i missing?

  6. Don’t let the diverter motor switch fool you in to thinking it is good. Check to make sure the switch is good through out its whole range of motion after it closes (clicks). I thought my switch was good but found there was a dead spot about half way through its closed motion. Put in a new switch and fixed the error.

  7. I just started getting the nE error… the strange thing is it happens about 3/4 of the way through the cycle.

    Isn’t that a little strange?

  8. After replacing a failed diverter motor on an LG WDS5040WW dishwasher, I noticed that the new diverter motor does not stop rotating, even after pressing the POWER button (off). I can hear the micro switch continuously click and unclick 3 times per minute. The only way to make it stop is to open the front door or pull the breaker off in the house. I checked that the micro switch is functional (continuity only when button pressed). What could be the cause of this? I am afraid that the diverter motor will wear out prematurely in such a situation. It may actually be the reason why it failed in the first place. Thanks.

    • Is it possible that you somehow messed up connections? For me it sounds like motor is trying to find initial position or there is no contact, i guess

  9. Hey Kari,

    By any chance were you able to resolve your nE error code? If so, what parts did you replace?


    One last thing if you don’t mind me asking, where were you able to pick up the replacement parts? I recently purchased an LG dishwasher for $100. The unit looks as if it was only used a couple times. By the stroke of bad luck, an error is displayed at the end of the cycle, nE. If the parts plus shipping are less than $100 I’ll be camper.

    I appreciate your time. Hope all is well, and stay safe.


  10. I replaced the Diverter Motor a couple weeks ago and am now getting the nE error again? Ideas/thoughts? What am I missing?

    • Hi kari, along with diverter motor issue there is chance that vario motor or wash motor failed. Did you check resistance of vario motor as well? All connectors tight and not loose?

      • Thanks for the reply. Checked it all last time I did it. Was now told that a spatula was preventing the wash arm below the top rack from moving. Before I pull it out again will likely buy a new diverter motor, cam, and micro switch just to have all I need. Hence wondering if there’s anything else. This about $30 worth of parts and I’ll return what is good to keep from having to do the pull out/put back in labor more than I have to.
