What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Food debris or filter restriction
- Kinked or blocked drain hose
- Garbage disposal drain connection issue
Basic checks
- Check for standing water.
- Inspect visible drain hose routing for kinks.
- Review the manual before cleaning filter or drain areas.
- Check for standing water after the cycle stops; if water remains, treat the issue as an active drain restriction.
- Inspect the visible drain hose for kinks or crushing; if routing is pinched, correct it before a retry.
- Listen for normal drain-pump activity from outside the cabinet; if it stays silent or loud, stop further retries.
Reset or retry steps
- Retry a short cycle only after safe cleaning, correct reassembly, and no visible leak.
When to call a technician
- Call LG service if OE returns after safe drain-path checks.
- Call service if the pump is inaccessible, noisy, or not moving water.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
