LG Dishwasher OE Error Code? Here’s How to Fix It!
If you’ve been greeted by the dreaded OE error code on your LG dishwasher, don’t fret it’s not as scary as it seems! This error simply means your dishwasher is having trouble draining, and with a little troubleshooting, you’ll probably be able to fix it yourself (no need to call for backup just yet). Let’s walk through what this error means, why it happens, and how you can get your dishwasher back to squeaky-clean glory.

What Does the LG Dishwasher OE Error Code Mean?
That stubborn OE error code on your LG dishwasher indicates a drainage issue. Essentially, your dishwasher is trying to empty water out, but something is stopping the flow. Instead of finishing up its cycle, it flashes the OE error to get your attention.
But don’t worry! Most of the time, this is caused by something minor like a clogged filter or kinked drain hose and is super manageable.
Read on for easy step-by-step solutions, and get ready to roll up your sleeves (but not too far; we’re dealing with water here!).
Common Causes of the OE Error Code
Before troubleshooting, it’s helpful to know what could be causing the problem. The most common reasons for the OE error code include:
- Clogged or Dirty Filters
Grease, food debris, and gunk can build up over time and block proper drainage.
- Kinked or Clogged Drain Hose
Your drain hose could have a kink or partial blockage that’s interrupting water flow.
- Faulty Drain Pump
If everything else checks out, the issue could lie with the drain pump itself, which may need repair or replacement.
- Garbage Disposal Connection Problems
If the dishwasher is connected to your garbage disposal, a blockage or improper setup could also cause trouble.
Now that we’ve covered the basics, let’s get to the solutions you came for!
How to Fix the LG Dishwasher OE Fault Code
1. Inspect and Clean the Filters
The first (and easiest!) step is to check if your dishwasher’s filter is clogged.
- How to check:
- Turn off and unplug the dishwasher for safety.
- Locate the filter at the bottom of the dishwasher it’s often near the back or center.
- Remove the filter and rinse it under warm water. Use a brush to scrub away any stuck-on debris.
- Reinstall the clean filter, ensuring it’s securely in place.
👉 Pro Tip: Cleaning your dishwasher filter regularly can prevent drainage issues from popping up in the first place. Aim for once a month if you run your dishwasher frequently!
2. Check the Drain Hose for Kinks or Clogs
Sometimes, the problem isn’t inside the dishwasher—it’s in the hose!
- How to check:
- Inspect the hose at the back of your dishwasher. Is it bent or kinked? Straighten it out!
- Disconnect the hose (place a bucket underneath to catch water) and flush it with warm water to clear any clogs.
👉 Pro Tip: While disconnecting and flushing the hose, check the connection point to the garbage disposal or sink for any blockages.
3. Run a Diagnostic Cycle
If cleaning the filters and checking the hose doesn’t work, try running your dishwasher’s built-in diagnostic mode. Refer to your LG dishwasher manual for instructions to identify if the drain pump is functioning properly.
4. Inspect and Clear the Garbage Disposal
If your dishwasher is connected to a garbage disposal, blockages there could back things up.
- How to check:
- Turn off the disposal and unplug it for safety.
- Disconnect the drain hose from the disposal and check for blockages.
- Make sure the knockout plug in the disposal (if it’s new) has been removed.
5. Test the Drain Pump
If you’ve ruled out clogs and blockages, the culprit might be the drain pump.
- How to check:
Running diagnostics may help you spot a faulty pump, but replacing it requires some technical know-how. If you’re comfortable with repairs, consult your manual—or contact an LG technician for help.
👉 Pro Tip: Many dishwashers have warranties that might cover pump replacement, so check your paperwork before attempting a DIY repair.
6. Still Stuck? Call for Support
If all else fails or you’re unsure how to proceed, it may be time to call a professional. LG support or a qualified technician can diagnose and resolve the issue quickly.
