LG dishwashers OE error

The dishwasher detected a drain issue.

OE

What this code can mean

LG identifies food-clogged filters, a drain-path problem, a restricted waste connection, or installation issues as common causes.

Safe first checks

  1. 1
    Turn off the appliance before inspecting the filter and drain path.
  2. 2
    Clean user-serviceable filters according to the model manual.
  3. 3
    Check the accessible drain hose for visible kinks.

Possible causes

  • Dishwasher filters contain food residue.
  • Drain hose or waste connection is restricted.
  • Drain installation is incorrect.
Stop conditions
  • Stop if water is leaking or electrical components are wet.
  • Request service when the drain path is inaccessible or the code persists.

Use LG support or an authorized servicer if filter and visible drain-path checks do not resolve the error.
