LG Dishwasher LE Error Code — What It Means
The LE code is a locked motor error on the water circulation pump. The pump motor stopped sending its feedback signal, so the control board halts the cycle. It often traces to a jammed impeller, a wiring fault, or a worn-out circulation pump motor.
Common Causes
- Jammed impeller Glass shards or food fragments lock the wash impeller so the motor cannot spin.
- Loose wiring harness A loose or corroded connector between the pump motor and board is the most common trigger.
- Seized motor rotor A worn bearing or failed oil seal adds drag until the rotor will not turn freely.
- Overheated motor A motor that ran hot can drop out until it cools, then trip LE again under load.
- Failed control board A bad main board can misread the motor feedback and post LE even with a good pump.
- Broken impeller blade A cracked blade unbalances the pump and can stall it mid-cycle.
Step-by-Step Fix
- Power the dishwasher off at the breaker for 30 to 45 minutes to let the motor cool
- Start a fresh cycle and see if LE clears after the cooldown
- If it returns, remove the lower spray arm and filter to reach the pump area
- Clear any glass or debris locking the wash impeller and spin it by hand to confirm it is free
- Inspect and reseat the pump motor wiring harness, looking for burnt or corroded pins
- Replace the circulation pump and motor assembly if the impeller is free and wiring is good
- Run a cycle and verify the motor runs and LE stays clear
Parts Often Needed
| Part | Notes |
|---|---|
| LG dishwasher circulation pump motor | Amazon | Match the wash pump and motor assembly to your full model number. |
| LG dishwasher wiring harness | Amazon | Only needed if pins are burnt or the harness is chafed through. |
| Wash arm or impeller | Amazon | Replace if a blade is cracked or the impeller is worn. |
When to Call a Pro
If the impeller spins freely and the wiring is solid but LE keeps returning, the pump motor or the control board has likely failed. A technician can read the motor winding resistance and confirm which part to replace before you order.
