What causes LG Dishwasher LE?

A glitch in the control that clears after a power reset (LG's first step). Something jammed in the wash pump so the impeller or blade can't turn, such as glass, a fruit pit or a bone, per LG's service bulletin. A locked or cracked rotor in the wash motor, per LG's service bulletin. A loose connector or a cut or broken wire between the wash motor and the main control board. On some older models (typically 2016 and earlier, per lgerrorcodes.com), a broken wire to the Hall sensor that tells the board the motor is turning. A failed wash pump motor or, less often, a main control board that isn't sending power to the motor.

How do I fix LG Dishwasher LE?

Press Power to turn the dishwasher off. Switch off the dishwasher's circuit breaker for 10 seconds, then turn it back on and run another cycle, as LG directs. Make sure no dishes, utensils or items hanging through the lower rack are touching the spray arm or sitting near the filter area, then try again. With the power off, take out the lower rack and the filter and look for broken glass, pits, bones or other debris in the sump that could jam the pump. LG's guide says to clean the filter every one or two weeks. If LE shows again after the reset, stop and request LG service. LG treats LE as a service repair.

When should I call a pro for LG Dishwasher LE?

LE comes back after the 10-second breaker reset. LG says the unit then requires service. You hear the dishwasher fill and click but the wash motor doesn't run, or it makes a grinding or humming noise. Checking the wash motor windings, connectors and Hall sensor wiring means pulling the unit and working near live parts. Technician guides say the motor is driven by an inverter whose voltage most meters can't read accurately. The dishwasher is still under warranty, so a technician visit may cost you nothing.

LG Dishwasher LE Error Code: Wash Motor Error (Meaning, Causes, Fixes)

Q: What does LG Dishwasher LE mean?

LE on an LG dishwasher means the wash (cleaning) motor isn't running normally. LG says it can be the motor itself or the wiring harness between the motor and the control board. Turn the dishwasher off, switch off its circuit breaker for 10 seconds, restore power and try another cycle. If LE comes back, LG says the dishwasher needs service. LG's US dishwasher error-code guide says the LE code may appear when the cleaning motor is not functioning normally, and that it requires inspection by a service technician. LG's East Africa and Nigeria help pages describe LE as a motor error that may point to the motor or to the wiring harness between the motor and the control board, and give a simple reset: power off, trip the breaker for 10 seconds, restore power and run another cycle. An LG service bulletin on LE error and motor noise lists the service causes as a locked impeller or blade in the wash pump, a locked or cracked wash-motor rotor, or a loose, cut or broken wiring connection. LE is different from nE, which LG uses when the impeller doesn't spin normally, often because a dish is touching it.
