  • Common Causes: Overloading, foreign objects, drain hose issues, clogged filters, leaks, thermistor issues.
  • Quick Fixes: Lighten dishwasher load, check for obstructions, inspect drain hose, clean filters, reset the dishwasher.

What does code LE mean on a LG dishwasher?

Got an LE error code usually means there’s some trouble with the motor or the wiring between the control board and the motor.

It could be a faulty motor, or maybe some of the wires got a little wonky. It’s kinda like when your headphones get all tangled and stop working right.

How do I fix the LE error on my LG washer?

Main causes and solution of an LE error code on an LG dishwasher is that the motor is working abnormally.

Overloading the dishwasher

When you overload the dishwasher with too many dishes, the motor’s gotta work extra hard to spin the tub and get the water moving.

This extra strain can make the motor stall or act funny, and that’s when you see the LE error code pop up.


If you’re seeing an LE error on your dishwasher, here’s a quick fix you can try. First, take out some dishes to lighten the load – you don’t want to overpack those racks.

Then, run the dishwasher on a normal cycle but skip the detergent this time.

We’re just seeing if the error clears up once the motor isn’t working so hard.

Foreign object stuck in the tub

Ever seen an LE error code on your LG dishwasher? It usually happens when something small like a coin, button, or other tiny thing gets stuck in the tub.

Here’s the lowdown:

A little item falls into the dishwasher during a wash cycle. It gets stuck in the tub or pump area, messing up the tub and impeller’s spin. This stops the motor from spinning the tub properly, and bam! LE error code pops up.


let’s unplug that dishwasher to keep things safe while we’re taking a look inside.

Pop open the tub and have a good look around for any sneaky foreign objects. Grab some pliers, tweezers, or just use your hand to fish out anything you find.

Give the tub a good spin by hand. It should move around easily without any weird obstructions.

Once you’re done, plug the dishwasher back in and run a normal wash cycle. Fingers crossed, that annoying LE error should be gone!

Temporary error

Did you get an LE error code on your LG dishwasher? No worries, it’s likely just a motor issue that might be caused by a temporary glitch.

Here’s what you can do to fix it:

First off, press the POWER button to turn the dishwasher off.

Then, disconnect it from power. You can either turn off the circuit breaker or just unplug it. Wait for at least 10 seconds.

After that, turn the circuit breaker back on or plug the dishwasher back in.

Finally, press the POWER button again to turn the dishwasher on and start a new cycle.

Drain hose issues

if the drain hose on your dishwasher is kinked or clogged up, it can mess with the water drainage.

When this happens, you might see the LE error code pop up, which basically means there’s a problem with the motor. 

This can be super annoying, but checking the drain hose for any blockages or bends is a good place to start.


Check the drain hose: Look for any kinks or clogs. Straighten it out and make sure nothing’s blocking it.

Check valve: If your hose has a check valve at the end, take it off. Sometimes they get stuck and stop the water from draining properly.

Proper installation: When you’re sliding the dishwasher back into place, make sure the hose isn’t getting kinked or pinched. Leave a bit of slack to avoid any problems.

Hose length: Keep the hose under 12 feet long. The end should be at least 12 inches but not more than 40 inches from the base of the dishwasher to prevent siphoning issues.

Drain filter clogged

Drain filter in your dishwasher is actually the little hero that catches food bits and debris before they hit the drain pump. If it gets clogged up, water flow can get restricted, and your dishwasher might not drain properly.

When this happens, you might see the LE error code pop up, which means there’s a problem with the circulation pump.


  • find and remove the drain filter. It’s usually hanging out at the bottom of the dishwasher tub.
  • Take a good look at the filter. Check for any debris or clogs. You might see food bits, grease, or other gunk that’s built up over time.
  • Give that filter a good clean under running water. A soft brush or toothpick can help get rid of any stuck-on stuff.
  • Once it’s all clean and shiny, pop the filter back into its original spot.
  • Now, run a test cycle without any dishes. This will help you make sure the dishwasher’s draining properly and that pesky LE error doesn’t come back.


If you’re dealing with an LE error code on your LG dishwasher, it might be due to some internal leakage.

When there’s a leak inside, it can mess up the water flow and cause problems with the motor, which triggers that annoying LE error.

Here are a few steps to help you troubleshoot and fix those leaks:

Check inside the dishwasher, especially around the door seal, tub, and base. Look for any cracks, holes, or damaged gaskets that might be causing the leak.

Make sure there are no kinks, clogs, or damages in the drain hose. These can stop proper drainage and cause water to back up into the dishwasher.

A clogged or misaligned filter can lead to drainage problems and leaks. Give it a good clean and make sure it’s properly installed.

If the inlet valve isn’t working right, it can cause overfilling and leaks. Make sure it’s functioning properly.

Look for any cracks, tears, or gaps in the door seal. If there’s any damage, water can escape during a cycle.

If your dishwasher isn’t properly levelled or installed, water might leak from the door or other areas. Double-check the installation.


It’s not because you overfilled it— that’s actually an FE error. Here’s the deal:

Common reasons for the LE error include:

  • Overloading the dishwasher, making the motor work too hard.
  • Foreign objects stuck in the tub, keeping it from spinning right.
  • Problems with the drain hose or a clogged drain filter, causing drainage issues.

Other possibilities are internal leakage or an abnormal thermistor resistance output.

To fix the LE error, do these steps first:

  1. Check for overloading.
  2. Look for any foreign objects stuck in there.
  3. Inspect the drain hose and filter for clogs.

Then, unplug your dishwasher for 5 minutes and plug it back in. Sometimes, it’s just a temporary glitch. If the error persists, it’s time to call LG for help. The motor or other parts might need repair or replacement.

Thermistor issue

That often points to an issue with the thermistor, which is basically the little sensor that keeps an eye on the water temperature.

If it’s acting up, it can mess with the whole operation and trigger that pesky LE code.

Here’s what you can do to sort it out:

Unplug the dishwasher: Just pull the plug and wait for about a minute. Then, plug it back in. This resets the control board and might clear the error.

Check the thermistor: If the code is still there, you’ll need to dig a bit deeper.

  1. The thermistor is usually near the sump assembly at the bottom of the dishwasher tub.
  2. Once you find it, disconnect the thermistor wires from the control board.
  3. Grab a multimeter and test the thermistor’s resistance. You’ll need to compare the reading to what’s in your model’s service manual. If it’s off, you’ll probably need a new thermistor.
