LG dishwasher AE or E1 code: internal leak warning

LG identifies dishwasher AE or E1 as an internal leak condition that activates the float switch. Resolve the cause before reuse. This page helps you distinguish the code, gather owner-accessible observations and decide when to stop and request service.

Safety boundary

  • Stop use for active leaks. Shut off an accessible water supply only if safe; keep away from wet electrical connections.
  • Owner checks are limited to visible observations and components explicitly user-accessible in the exact model manual. Do not remove panels, dry a base pan, bypass a sensor or test live wiring.
Displayed codeAE / E1

An internal leak has activated the float switch. The alert does not prove that the switch itself has failed.

LG US dishwashers listing AE or E1 in their model documentation; this is not an LG washing-machine code guide.

Checks in order

  1. 01

    Confirm whether the display says AE/E1 or IE; photograph it rather than guessing the character order.

  2. 02

    Stop use for leakage and record when the alert appears. No visible puddle is insufficient evidence to dismiss an internal leak warning.

  3. 03

    Record detergent type and dose, any visible door-seal contamination and recent installation changes. Inspect only surfaces the owner manual makes accessible.

  4. 04

    Contact LG support or a qualified service provider if the cause is unresolved. Do not remove the kick plate, drain or dry a base pan, or run repeated cycles to clear the code.

Is E1 the same as IE?

No. LG's dishwasher AE/E1 guidance concerns an internal leak. Its IE guidance concerns insufficient fill. Read the display and the exact dishwasher manual before choosing a troubleshooting path; a transposed character changes the decision.

Can I reset AE and keep washing?

Clearing an alert does not establish that the leak has been repaired. LG says to correct the underlying cause before reuse. This owner guide therefore stops at accessible observations and service escalation rather than internal float-switch access or pan drying.
