LG Washer Error Code AE: Meaning and Fix
Reading the washer display
On a washer the code appears on the digital display or as a pattern of flashing cycle lights. Note it exactly, including any dashes or sub-codes, then unplug the washer for five minutes and run a short drain cycle to see whether it returns. LG codes are short letter pairs; a capital O differs from a zero.
LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.
What causes AE
- Loose inlet hose connection
- Top loaders: coin or object caught near the wash plate
- Leak at the pump or door boot
- Failed leak sensor
- Cut or worn hose
How to fix it
- Close the faucets and unplug the washer.
- Check inlet hose connections and look for drips.
- Inspect the hoses for cuts.
- Dry the base, restore power after a minute and restart.
- On top loaders, remove any coins or objects trapped between the wash plate and drum.
- If AE repeats with no leak or jam, request service.
