LG Dishwasher Error Codes: Complete Guide to Every Fault Code

Quick Answer

LG dishwashers use a direct-drive inverter motor and display single or two-character fault codes on the control panel. The most searched code by far is AE (leak detected, 6500 searches/month), followed by CL (child lock), OE (drain timeout), and LE (motor locked). LG's AE code uses a resistance-based sensor in the base pan rather than a mechanical float, making it far more sensitive to condensation than competing brands. Most codes clear by unplugging for 60 seconds; AE specifically may require a 2-hour unplug for the base pan to dry.

How to Identify Your Error Code

Write down the exact code displayed

Write down the exact code displayed. If the code is AE, do not tilt the unit yet. Unplug the dishwasher first and wait 2 hours to let any condensation in the base pan evaporate before investigating further.

Frequently Asked Questions

What is the most common LG dishwasher error code?

AE is the most searched LG dishwasher code at roughly 6500 searches per month. It means the base pan leak sensor was triggered, but in most cases condensation from a hot cycle is the cause rather than an actual water leak. Unplug for 2 hours and the code usually clears on its own.

How do I clear an error code on an LG dishwasher?

Press and hold Power for 3 seconds or unplug the dishwasher for 60 seconds. For AE codes specifically, the unit needs to be unplugged for at least 2 hours so the base pan can dry out. If the code returns after restarting a cycle, the underlying component needs attention.

Can I enter LG dishwasher service mode to retrieve stored fault codes?

Yes. Press and hold Dual Zone and High Temp simultaneously for 3 seconds to enter service mode on LG direct-drive dishwashers. The display will show any stored fault codes.
