LE
LG Dishwasher
Severity: CriticalWhat Does This Error Mean?
The LE error means the wash motor in your LG dishwasher has a problem. The motor cannot spin the spray arms properly. This is often caused by a blockage, but can also mean a motor failure.
Affected Models
- LDF5545ST
- LDT7808ST
- LDFN4542S
- Most LG dishwashers with digital displays
Common Causes
- Food debris or broken glass jamming the wash impeller
- Worn or burned-out wash motor
- Wiring harness issue between the motor and control board
- Faulty main control board sending incorrect signals to the motor
- Motor overheating due to prolonged use or blocked ventilation
How to Fix It
-
Turn off the dishwasher and unplug it from the wall outlet.
Safety first — never work on a plugged-in appliance.
-
Remove the bottom dish rack and check the spray arm area for debris.
Look for broken glass, food chunks, or anything jamming the spray arm.
-
Spin the lower spray arm by hand to check if it moves freely.
If it feels stuck or grinds, something is blocking it underneath.
-
Clean the filter assembly at the bottom of the tub.
Remove any food particles or debris that could reach the motor.
-
Plug the dishwasher back in, wait 1 minute, and start a new cycle.
If the LE error returns immediately, the motor itself is likely faulty.
When to Call a Professional
If clearing debris does not fix the error, the wash motor likely needs replacement. This is not a DIY repair for most people. Contact LG support or a certified appliance technician. Expect repair costs of $200–$400 including parts and labor.
Frequently Asked Questions
Can I still use my LG dishwasher with the LE error?
No — the dishes will not get clean because the spray arms cannot spin. Running it with a jammed motor could cause further damage. Fix the problem before using the dishwasher again.
What causes the LE error most often?
The most common cause is food debris or broken glass jamming the impeller. This is the small propeller under the filter that pushes water to the spray arms. Clearing the blockage usually fixes it. If the motor itself is burned out, it will need replacement.
How much does it cost to replace an LG dishwasher motor?
A new wash motor for an LG dishwasher costs $80–$150 for the part. Labor typically adds another $100–$200. Total repair cost is usually $200–$400. If your dishwasher is over 8 years old, consider whether a new one makes more sense.
