LG Dishwasher OE Error Code

OE is a drain condition often related to food debris, filters, the drain hose, air gap, or disposal connection. The safe scope is cleaning accessible filters and checking visible drain-path issues.

Applies to LG dishwasher

What the appliance detected

Detected condition

LG says OE appears when the dishwasher is not draining properly.

What may contribute

Possible causes

  • Food debris or clogged filters are restricting drainage.
  • The drain hose is kinked, compressed, damaged, or installed incorrectly.
  • The air gap or in-sink disposal connection is blocked.
  • A drain problem remains after accessible maintenance.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code and stop for water hazards

    • Photograph or write down OE before clearing the display.
    • Stop if water is leaking, pooling near electrical parts, or creating a slipping hazard.

  2. Clean accessible debris and filters

    • Turn the dishwasher off before removing large food debris from the tub.
    • Clean the accessible filter according to the owner manual, being cautious of sharp stainless-steel edges.

  3. Check accessible drain points

    • Visually check the accessible drain hose for kinks or compression without pulling the dishwasher out or disconnecting hidden plumbing.
    • If the installation has an air gap or disposal connection, clear only accessible debris as the model and installation documentation allow.

Actions not recommended

  • Do not remove panels, pull the dishwasher from the cabinet, disassemble the drain pump, or reach into hidden plumbing.
  • Do not use sharp tools inside the dishwasher drain path or continue cycling a unit that may overflow.
  • Do not modify a disposal connection or air-gap installation unless you are qualified to perform that plumbing work.

When to stop and request service

  • Request service if OE returns after accessible filter and visible drain-path checks.
  • Use a qualified installer or plumber for hidden drain hose routing, disposal knockout, air-gap, or plumbing concerns.
  • Stop immediately for leaks, standing water near electrical parts, damaged hoses, or any required disassembly.
