LG Dishwasher LE Error Code – Meaning, Causes & Fix
The LE error code on an LG dishwasher stands for 'Locked motor Error' — it means the wash pump motor has stalled, is drawing excessive current, or cannot rotate freely. LG uses this code across its dishwasher lineup, including the LDF, LDT, and LSDT series. The LE error typically appears mid-cycle or at the beginning of a wash cycle when the motor attempts to start. The motor can become locked due to a foreign object jamming the pump impeller, a motor winding failure, a failed capacitor in the motor circuit, or in some cases excessive detergent suds reducing motor efficiency. Understanding which component is causing the motor lock is the key to fixing LE quickly, and in the majority of cases the cause is a physical obstruction that can be removed at home without any parts replacement.
What it means
The LG dishwasher's wash pump motor is stalled, locked, or drawing excessive current — the motor cannot rotate and the cycle is halted.
Severity
ModerateCan you fix it yourself?
Yes in most cases — clearing the pump impeller of obstructions resolves LE the majority of the time.
Call a technician when
Contact a technician if the motor itself has failed or if the main control board needs replacement.
What Does LE Mean?
LG dishwashers use a direct-drive wash pump motor to circulate water through the spray arms during a wash cycle. The motor control circuit monitors the current drawn by the motor continuously during operation. When the motor draws current significantly above its rated value — or fails to start at all — the control board interprets this as a locked rotor condition and immediately stops the motor to prevent thermal damage or fire risk. The LE code is then logged and displayed.
The motor lock condition has two primary origins: 1. Mechanical lock — a physical obstruction (glass shard, bone chip, pit, twist tie, or other debris) has entered the pump housing and jammed the impeller. The motor tries to turn, hits resistance, draws high current, and the board shuts it down. 2. Electrical lock — the motor windings have partially failed, a run capacitor has failed (on motors that use one), or the motor has seized internally due to bearing failure. In these cases, the motor cannot rotate even with no obstruction present.
LE vs. OE confusion: LE is a motor/pump lock error. OE is a drain error. Both can occur together if a jammed pump impeller prevents both washing and draining, but they have different root causes.
What Causes This Error?
- Foreign object jammed in the wash pump impeller — glass fragments, food bones, small utensil parts, or plastic debris entering the pump through the filter
- Excessive detergent suds overloading the pump — using non-dishwasher detergent or too much detergent creates foam that reduces pump hydraulic efficiency
- Failed wash motor — internal bearing seizure or winding failure preventing rotation
- Clogged or dirty pump filter screen restricting flow enough to create back-pressure on the impeller
- Failed motor start capacitor (on applicable motor variants) — the motor cannot build starting torque without a functioning capacitor
- Main PCB (printed circuit board) failure causing incorrect motor drive signals
- Overheated motor from a previous extended run — thermal protection trips and LE appears as a secondary code
How to Fix LE
- 1
Power off and unplug the dishwasher. Safety first — disconnect power before accessing the pump. Remove the lower dish rack and set it aside.
- 2
Remove and clean the filter assembly. LG dishwashers have a cylindrical mesh filter and a flat coarse filter at the bottom of the tub. Turn the cylindrical filter counterclockwise to unlock it, lift it out, then lift out the flat filter below. Rinse both under warm running water and use a soft brush to clear any debris. Reinstall both filters correctly.
- 3
Inspect the pump inlet for obstructions. With the filters removed, look down into the sump area with a flashlight. You may be able to see or feel a glass shard, pit, or small bone lodged near the impeller opening. Use needle-nose pliers or tweezers to remove any debris. Never put fingers into the pump inlet without the machine unplugged.
- 4
Run a short cycle with no dishes to test. If the obstruction was the cause, LE will not return. Listen during the first 2–3 minutes — you should hear the pump running smoothly without grinding or buzzing sounds.
- 5
If LE returns immediately, the pump motor itself may have failed. To confirm, access the pump from below (or from the front after tilting the machine): disconnect the motor electrical connector and use a multimeter to check motor winding resistance. Each winding pair should show 5–20 ohms of resistance. An open reading (OL) indicates a failed motor winding.
- 6
Check for suds if you recently changed detergent or used a non-dishwasher soap. Leave the dishwasher door open for 30 minutes to allow suds to subside, then run a Rinse Only cycle. If LE does not appear during a rinse cycle (no detergent), excessive suds from the previous cycle was the cause. Always use dishwasher-specific detergent in the recommended amount.
- 7
If the motor tests electrically open or the motor makes a buzzing/humming sound but does not turn, the motor assembly needs replacement. LG wash pump motor assemblies (part numbers vary by model — use your model number at lgparts.com or encompassparts.com) typically cost $80–$140 for the part. The repair involves removing the door, lower panel, and pump assembly — a 60–90 minute DIY repair.
When to Call a Professional
If cleaning the pump and filter does not resolve LE, and the motor tests as failed, LG recommends contacting an LG-authorized service center. LG dishwashers come with a 1-year parts and labor warranty; the direct-drive motor carries a separate 5-year limited warranty on some models. Contact LG support at lg.com/us/support or call 1-800-243-0000. A motor replacement service call typically costs $150–$250 including labor.
Can You Still Use the Device?
Do not run the dishwasher while LE is active. Repeated attempts to run the machine with a jammed or failed motor can damage the motor windings through heat buildup, potentially turning a simple obstruction-clearance repair into a full motor replacement. Clear the obstruction or address the motor fault before resuming use.
