LG AELeak / aqua error

An LG AE (aqua error) means the leak sensor detected water in the base pan and shut the dishwasher off to protect your floor. Often it's a small spill, condensation, or oversudsing rather than a real flood — dry the base and restart. If AE returns quickly, water is genuinely leaking into the base from a hose, the door gasket, or the sump; find and fix that.

🔧 From our repair bench: AE is a base-pan leak trip — dry it out and watch whether it comes back before chasing a part.

🐜 Straight talk: this points you at the likely cause — it's not a guarantee, and every machine is different. Cut the power (and shut off gas or water) before you touch anything, test to confirm the part is actually bad before you buy, and if it's beyond you, get a pro. No shame in that.

The Tools to Test + Fix With

No part — dry the base & cut suds

Soak the water out of the base pan so the float drops, and cut back detergent/rinse-aid if it's sudsing. Clears a one-time AE.

Fix the leak source (hose / gasket / sump)

If AE returns fast, water is still entering the base — check the door gasket, hose clamps, and sump, then replace the failed part.

Can you fix it yourself?

Safe to Try · Know the Risk · Call a Pro

General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.

✅ Safe to try yourself

  • Turn it off and soak the water out of the base pan so the float drops.
  • Cut back detergent if it's oversudsing.
  • Restart — if AE clears and stays gone, it was a one-time spill.

⚠️ Doable — know the risk

  • Tracing and replacing a leaking gasket/hose — moderate; power and water off.

🛑 Call a pro — don't touch this

  • A leak you can't locate, or water reaching the wiring/control.
