Im getting error code "LE" on my lg dishwasher

I think you may be getting IE code which relates to water inlet problems. Either the water pressure is low or the inlet valve may not be working properly.

Display Condition LE = Motor Error

Possible Cause For Error Occurrence:

Wiring connection is OK?
The Impeller of Washing Pump is locked.
The rotor of Washing Motor is locked.
The Blade is locked.


Remedy:

Check the wiring connection.
Replace the cause of restriction.
Replace the Washing Motor.
Replace the PCB.

Try the following steps:

Unplug the washing machine if you see an LE error on the two-digit display electronic readout. This error indicates a miscommunication between the control panel and wash motor.

Press and hold the "Start/Pause" button on the front panel for five seconds.

Plug the LG dishwasher back in.

Run a cycle. The LE code will clear.

Le error is a motor error. either there is something lodged in the pump holding the blades or the motor itself needs to be replaced

I just had my LG dishwasher fixed. I told the repair man that LE light was comming on. Even over the phone the repairman said its probably broken wires on the door. Me being in construction for years looked around the door for wires. Anyway the repairman took off 6 screws around the door, took the cover off. You will see about 50 wires taped together. He pulled them aside and visually checked them one by one. Sure enough two were broken in two. He twisted them together put tape and he was gone. $87.50 Still Working!

hi,
le means locked motor disassemble the filter and work your way down to the macerator(steel chopper blade) remove it and see if the side labeled "this side up" is really up, its in english... dont think the chinese labourers paid attention to the warning cause i have seen alot that were wrong way

if it was installed correctly order the complete motor/sump assembly btw you do know LG d/w came with a 2 year warranty right? and some of the water distribution system had a longer limited warranty
read your manual, it states warranty, then price the part, then call warranty depot to ask them their service call and labour to install motor/sump

LE error code means that there is a problem with the motor.  One thing to check is to remove the front door panel and check the wiring harness to see if there are any broken wires.  If there is, repair the wire connections and see if the dishwasher returns to normal.  If not, then the motor assembly will need to be replaced.
