LG Dishwasher AE Error – Meaning & Easy Fixes
If your LG dishwasher is showing the AE error code, it means the appliance has detected a water leak or excess moisture inside the unit. As a safety measure, the dishwasher automatically stops to prevent further damage.
In this guide, we explain what the LG dishwasher AE error means and walk you through easy and safe steps to fix the issue.
What Does the LG Dishwasher AE Error Mean?
The AE error code on an LG dishwasher indicates that the leak detection system has been activated. This usually happens when water accumulates in the base of the dishwasher.
Common causes include:
- Small internal water leaks
- Excessive detergent or suds
- Loose hoses or connections
- Door seal or gasket issues
- Temporary sensor glitches
Quick Fix Summary
| Possible Cause | Difficulty | Recommended Solution |
|---|---|---|
| Temporary sensor glitch | Easy | Power reset |
| Excess suds | Easy | Reduce detergent usage |
| Minor water leak | Medium | Inspect hoses and seals |
| Door gasket issue | Medium | Check door seal |
| Persistent leak | Hard | Contact LG support |
Fix 1: Power Reset the Dishwasher
Sometimes the AE error appears due to a temporary sensor or control board glitch.
Steps:
- Turn off the dishwasher
- Unplug it from the power source
- Wait 10–15 minutes
- Plug it back in and start a new cycle
If the error does not return, the issue was temporary.
Fix 2: Check for Excess Detergent or Suds
Using too much detergent can cause excessive foam, triggering the leak sensor.
- Use only dishwasher-safe detergent
- Avoid overfilling the detergent compartment
- Clean out visible suds if present
Excess suds are a very common cause of AE errors.
Fix 3: Inspect the Door Seal and Gasket
A damaged or misaligned door seal may allow water to leak.
Check that:
- The door gasket is clean and intact
- No food debris is stuck in the seal
- The door closes evenly and firmly
Clean the seal gently with a damp cloth if needed.
Fix 4: Check Hoses and Connections
Inspect the dishwasher’s hoses:
- Look for loose or leaking connections
- Check for visible cracks or damage
- Ensure hoses are securely attached
Minor leaks can activate the AE error even if water is not visible.
When to Contact LG Support
Contact LG support if:
- The AE error keeps returning
- You notice water pooling under the dishwasher
- The dishwasher stops mid-cycle repeatedly
A professional inspection may be required for internal leaks.
How to Prevent AE Errors in the Future
- Use the correct amount of detergent
- Clean the door seal regularly
- Avoid overloading the dishwasher
- Check hoses periodically
- Perform routine maintenance cycles
