- Displayed OE code in that LG support scope
Region: Global. This page does not generalize the code to every LG washer.
What the code means
The dishwasher did not drain as expected. Pelledor keeps this page scoped to the official LG no-drain checks and avoids naming a failed part from the code alone.
Confirmed: LG documents dishwasher OE as a drain-related error condition, with checks focused on the drain hose path and filters.
Can you keep using it?
Only after safe supply checks and only if the code clears.
When to stop
Stop if water leaks, standing water remains, access is unsafe, or the dishwasher would need to be moved.
When to call a professional
Request LG service if OE continues after accessible drain and filter checks.
Safe checks
- Confirm the display reads OE.
- Check the accessible drain hose path for kinks or restriction.
- Inspect and clean the filter area if the model procedure allows safe access.
- Do not pull out a built-in dishwasher or work around water and power unsafely.
Confirmed by the manufacturer
- LG’s dishwasher OE help article treats the code as a drain-related condition.
- Drain hose routing or restriction can prevent proper draining.
- Filter or sump debris can interfere with draining.
Commonly associated with this fault
- A kinked drain hose, restricted drain path, or dirty filter can fit LG’s official OE guidance.
Not confirmed for this exact model
- A failed drain pump, sensor, control, or harness is not confirmed by dishwasher OE alone.
