What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Stop normal use and turn off the water supply if safe.
- Look for visible water from a dry position without tipping, pulling out or opening the appliance.
- Record the complete display, model and detergent used for LG service.
Applicability
Regional guidance · United States
AE follows the cited U.S. guide. The E1/AE equivalence is documented for the models named in manual MFL62077193; do not extend it to every LG dishwasher.
Reset or retry steps
- Do not resume use until the leak cause is found and corrected.
When to call a technician
- Contact LG service for a persistent AE warning, even when no water is visible on the floor.
- Arrange qualified help for leaks, leveling or door alignment; do not pull out an installed dishwasher.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not repeatedly reset, tip, or move the appliance to clear a leak code.
- Do not disconnect inlet hoses until the water supply is off.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Water leaking from the dishwasher
- Excess foam from an unsuitable detergent or too much detergent
- A leveling or door-alignment problem
FAQ
What does LG Dishwasher code AE usually mean?
Usually indicates a leak or overfill warning; confirm the exact model and display. Model context matters: LG’s current U.S. guide groups AE with overfill or leak warnings. It lists excess foam and installation conditions as possibilities, not a confirmed component diagnosis.
Can I keep using the dishwasher with code AE?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Water and electricity risk: stop use and disconnect power if safe.
When should I call a technician for LG AE?
Contact LG service for a persistent AE warning, even when no water is visible on the floor. A qualified technician may check the listed symptoms and source guidance against the model's service information before treating any part as failed.
