What is the LG Dishwasher LE error?#
LE on an LG dishwasher — sometimes paired with CE — is a wash motor error: the motor that drives the spray arms is not running correctly, so water does not circulate and dishes come out dirty. You may hear a hum with no spray, or catch a burning smell from under the unit, which is your cue to stop the cycle. The most common cause is the wash motor itself, so the first thing I check on QuadWash models is whether the multi-motion wash arm is free to turn.
LE on a LG Dishwasher: likely causes and repair cost#
On a LG Dishwasher, the LE code signals: motor error.
| Likely cause | Typical likelihood |
|---|---|
| Wash motor failure | Most common |
| Wiring issue | Common |
Typical professional repair: $200–$380 · Difficulty: professional only · usually a technician job
Symptoms that often accompany LE: No water spraying during cycle; Humming sound but dishes not getting clean; Cycle stopping after fill completes; Burning smell from under dishwasher
Technician diagnostic sequence for LE:
- Reset the dishwasher by turning off the circuit breaker for 5 minutes, then restart — transient motor faults sometimes clear with a full power cycle
- Check if the wash motor (main circulation pump) is jammed by foreign objects — a broken piece of dish, glass shard, or food bone can wedge the impeller
- Access the motor from under the dishwasher and attempt to rotate the impeller by hand — it should spin freely with light resistance
- Test motor winding resistance — the LG dishwasher wash motor should read 3-8 ohms between the phase leads
- If the motor spins freely and windings test OK, the motor control circuit on the main board may have failed
Parts a technician may check or replace: Wash Motor/Pump Assembly; Main Control Board; Motor Impeller
Field note: LG QuadWash models have a multi-motion wash arm driven by the same motor. If LE appears only during the QuadWash multi-spray phase, the wash arm hub bearing may be seized — check the wash arm rotation before condemning the motor.

How to troubleshoot the LE error yourself#
LE leaves owners a limited but worthwhile check before it becomes a service call. Turn the dishwasher off at the breaker, then reach into the tub and confirm the wash arms spin freely by hand — on QuadWash models a seized wash-arm hub bearing can mimic a dead motor and trip LE, and freeing a jammed arm sometimes resolves it. Clear any debris, glass, or utensil that has fallen into the sump and could be binding the impeller. If you noticed a burning smell, do not keep running the machine. Stop and call a technician if the wash arms turn freely and the sump is clear but LE persists, or if there was any burning odor: the wash motor or pump assembly has failed, and LG rates LE a professional repair that means removing the motor from beneath the tub.
Is the LG Dishwasher LE error worth fixing?#
LE is worth a real repair-or-replace look because the wash motor is one of the priciest parts in a dishwasher. A professional repair runs $200–$380 to replace the wash motor and pump assembly or the impeller — still under half the cost of a comparable new dishwasher, so on a newer or mid-life machine I recommend fixing it. The tipping point is an older dishwasher where a motor job approaches half the price of new and other parts are worn, at which point replacement is the smarter spend.

LG Dishwasher LE: frequently asked questions#
What does the LE error mean on a LG Dishwasher?#
LE, sometimes shown with CE, is a wash motor error. The motor that drives the spray arms is not running correctly, so water will not circulate and dishes stay dirty.
Is it safe to keep using a LG Dishwasher that shows the LE error?#
No, especially with a burning smell. A stalled wash motor can overheat, so stop the cycle and cut power until the motor is checked.
Can I clear the LE error myself, or do I need a technician?#
You can free a jammed wash arm and clear the sump, which sometimes resolves a QuadWash LE. If it returns or there was a burning smell, the wash motor needs a technician.
How much does it cost to repair the LE error on a LG Dishwasher?#
A professional LE repair typically runs $200–$380, covering the wash motor and pump assembly or the motor impeller.
Which parts usually fail when a dishwasher throws the LE code?#
The wash motor and pump assembly is the usual failure, sometimes with a damaged impeller or a seized wash-arm hub bearing on QuadWash models.
Is a LG Dishwasher with the LE error worth repairing?#
On a newer machine, yes — $200–$380 is below replacement cost. On an older dishwasher with other wear, a motor job nearing half the price of new tips toward replacing.
Why does wash motor failure trigger the LE error?#
The wash motor reports its operation to the board while circulating water. When the motor stalls, shorts, or a winding fails, that feedback drops out and the board posts LE.
