[SOLVED] LG Dishwasher LE Error Code – KCSCFM Repair

When LG dishwashers display an LE error code on the display panel, it means there is a problem with the motor assembly. This can be caused by anything from food particles clogging up the pump or other parts of the machine to faulty wiring connections or even water damage inside your LG appliance.

LG dishwashers are designed to help every busy family with their dishes, but LG dishwasher LE error code can get in the way of your day-to-day life. We’ll show you what the LG dishwasher LE error code stands for and how to fix it.

What Does The LG Dishwasher LE Error Code Mean?

LG Dishwasher LE Error Code

The LE error code on your LG dishwasher means it’s having a motor issue.

The LE code first appeared on LG dishwashers, signaling an issue with the motor. Usually, there are several reasons for the problem. The most common of these is a wiring issue — but that’s not all! You might also have a problem with the motor itself (rotor or blade) or with the printed circuit board (PCB).

Reset the LG Dishwasher

In many cases resetting the LG dishwasher can solve the issue. The first thing you should do when encountering an LG dishwasher LE error code is resetting it before starting any further troubleshooting steps.

The easiest way to complete this task is to shut off your power at home’s circuit breaker and turn it back on after 15 seconds. LG dishwashers are designed to reset themselves as soon you turn your LG appliance back on.

Sometimes, you may have to wait for 30 minutes before restarting the machine. It will reset the dishwasher and allow the motor time to cool if it has become overheated due to excessive usage.

What Causes The LG Dishwasher LE Error Code?

The LE error code on your LG dishwasher means it’s having a motor issue. The LE code first appeared on LG dishwashers, signaling an issue with the motor. Usually, there are several reasons for the problem. The most common of these is a wiring issue — but that’s not all! You might also have a problem with the motor itself (rotor or blade) or with the printed circuit board (PCB).

Broken or Faulty Wiring

Examine the wiring harness, which connects the pump and control board. The harness may be poorly fixed or damaged. To access it, you need to remove the cover on the side of the machine, so check for any damage to the door panel as well. Once you’ve removed all the screws and pulled off any glued insulation, examine the wires to make sure none are loose or damaged.

Below, you will see a bunch of wires. A white plastic cover keeps them neatly in place — until it’s time to use the dishwasher. The resin is used to make the appliance soundproof; when the door opens and closes, its ends become entangled in the stuff. This damages the wire coating and can even cause short circuits.

To solve the problem, free the terminals from the insulation with a sharp knife, strip the wires, solder them and wrap them in electrical tape.

Stuck Drain Impeller

Inspect the dishwasher drain impeller to make sure it has not become damaged or worn out. If it is, replace it with a new one. The impeller on your dishwasher helps direct water from the washbasin to the drain hose and out of the machine. Your dishwasher’s drain impeller should not be obstructed, otherwise, it will result in LG Dishwasher LE Error Code. Make sure the impeller can spin freely. Also, make sure large pieces of food cannot slip through the food chopper.

You can check the impeller for damage or clogs which can cause the spray arms not to function properly or simply replace it if you already have the replacement part.

When your dishwasher stops spraying water at one or more of the arms even though there is water inside the dishwasher, try checking the impeller to see if it is broken or obstructed. If it is, you can replace it with a new impeller part. Otherwise, if you already have the replacement part on hand, you can just install it on the motor shaft.

Faulty Drain Pump

The drain pump is the little guy that makes all the difference. If this part breaks down and starts to act up, you can be sure that your dishwasher will act up right alongside it. The drain pump is not motorized — instead, it’s an impeller that forces water through the drain hose. 

To determine if the drain pump is defective, check the pump for continuity using a multimeter. If the motor has no continuity, or if it’s getting power but not spinning, replace the pump motor.

Main control board fails

If a dishwasher shows LG Dishwasher LE Error Code, the issue is likely to be with its PCB. This small, intricate computer chip, responsible for sending commands to the machine’s other components, could have damaged contacts, tracks, or burned-out elements. To solve the issue once and for all, the processor has to be replaced entirely. It costs around $150 – $200.

Final Thoughts

The LG dishwasher display will show the LG dishwasher LE error code if there is a problem with the motor. This issue can be caused by broken or faulty wiring, stuck drain impeller, fault pump, and main control board failure. 

The LG dishwasher displays this message when it has identified one of these conditions on its own. If your LG dishwashers’ motor needs service, do not delay and contact LG immediately for help.
