LG Dishwasher AE Error Code: Why Leak Protection Activates
An LG dishwasher AE error code means the appliance has detected a leak condition and activated its protective system. On models covered by LG's AE and E1 guidance, water inside the base activates a float switch.
Finding the source matters more than clearing the display, even when the kitchen floor looks dry. If the warning continues, professional LG appliance repair in Waltham can help identify the underlying problem.
What Does LG Dishwasher AE Mean When No Leak Is Visible?
The visible washing compartment and the base beneath it are different areas. An empty tub does not tell you whether water reached the dishwasher leak protection system.
LG also notes that water in the base may already have evaporated by the time it is inspected. Consequently, not seeing water now does not establish that the original warning was false.
The official LG AE and E1 error code guide explains the role of the float switch and base pan.
Record what happened before the warning: a detergent change, recent installation, visible foam, or water near the door. That sequence helps distinguish an isolated overflow from a fault that returns during use.
Common Conditions That Can Trigger LG Dishwasher AE
Excessive Foam From Incorrect Detergent
Hand dishwashing liquid produces suds unsuitable for an automatic dishwasher. Excessive foam and water overflow need a different response from replacing a mechanical component.
Uneven Installation or Door Misalignment
LG includes leveling and door alignment among possible contributors to leak or overfill warnings.
If the door looks uneven after installation, report it rather than adjusting mounting hardware experimentally. Proper leveling and door positioning are also important parts of professional dishwasher installation.
Water Escaping Inside the Dishwasher
A hidden dishwasher leak may require inspection beyond the surfaces a homeowner can see. Water can reach the base without producing an obvious puddle on the kitchen floor.
Water Entering the Heat Dry Blower
LG identifies water entering the Heat Dry blower as another possible trigger on applicable models. Do not pour water into openings to test the dishwasher.
These possibilities appear in LG's dishwasher error-code guidance. Their relevance depends on the model and what actually happened.
Safe Checks Before Running Another LG Dishwasher Cycle
Stop the Dishwasher and Document the AE Warning
Photograph the LG dishwasher AE error code and note whether it appeared during filling, washing, or draining.
Record any unusual noise, foam, or visible moisture without running another cycle to recreate the problem.
Close the dishwasher's water supply valve if safely accessible when a leak is suspected. Follow your model's instructions for stopping the appliance.
Check Dishwasher Detergent and Door Clearance
Read the detergent label and confirm it is intended for automatic dishwashers. Remove items that interfere with normal door closure.
Look for visible residue or moisture around the door. Keep observations specific: where water appeared is useful; assuming that the door gasket needs replacement is premature.
Keep Base-Pan Inspection Within Safe Limits
LG publishes a drying procedure for certain accessible dishwasher base pans that begins with switching off the circuit breaker.
Panel arrangements differ, so use only instructions matching your appliance.
Do not reach beneath an energized dishwasher, bypass the float switch, or tilt the appliance to empty hidden water.
If access is uncertain, leave inspection to a technician.
Why Drying the Dishwasher Base Pan May Not Resolve AE
Removing water addresses the condition that activated LG dishwasher leak protection. It does not, by itself, explain how the water arrived there.
If the AE error code returns, arrange professional dishwasher repair. Provide the technician with the detergent details, installation history, and timing of the warning.
When Professional LG Dishwasher Diagnosis Is Necessary
Ask what was found and what will be checked after repair. For a recurring fault, the goal is to verify the cause and confirm normal operation, rather than simply make the display clear.

A recurring AE warning should not be treated as a simple reset problem. Identifying the original source of moisture is essential before returning the appliance to regular use.
LG Dishwasher AE Error Code: Frequently Asked Questions
Common Questions About LG AE and Leak Protection
Can the LG Dishwasher AE Error Be Reset Permanently?
A reset cannot permanently resolve an ongoing leak. Follow LG's procedure only after the underlying condition has been addressed.
If the AE error returns after resetting, further inspection is necessary.
Does AE Mean the Float Switch Needs Replacing?
No. An activated dishwasher float switch may be responding to water as intended.
The AE code alone is not enough to select a replacement part. The cause of the leak-protection activation must be identified first.
Is AE the Same as an LG Dishwasher Drain Error?
No. LG distinguishes leak-related AE from drainage-related OE.
Record the exact letters before following troubleshooting instructions because the appropriate checks are different.
Is LG AE Similar to Bosch Dishwasher Error E15?
Both errors involve leak protection, but they occur on different appliance systems.
For another brand's leak-protection warning, our Bosch dishwasher E15 error code guide explains that separate scenario.
Its instructions should not replace your LG manual.
