LG dishwasher AE error code
What AE means on an LG dishwasher
Anti-flood protection: leak or water in the base.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When an LG dishwasher shows AE, its anti-flood protection has gone off because it has found a leak or water sitting in the base of the machine. You may also notice the pump keeps running and won't stop, which is the dishwasher trying to clear that water. Switching off and unplugging it is a sensible step while you wait for help.
Engineers sometimes find the leak is coming from the seal on the chamber at the side of the dishwasher, where water passes through on its way in. The chamber itself can be perfectly sound while its seal has stopped holding water in.
An engineer will look for where the water is escaping and check the seals and chambers around the inside of the machine. A worn seal can sometimes be cleaned to help in the short term, but the lasting fix is usually to replace it, then run the dishwasher through a test to make sure it works with no further leaks. The replacement seal may need to be ordered, so the repair can take a second visit to finish.

Before you check anything yourself
- Switch the dishwasher off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the dishwasher apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
