What to check first
Can I keep using it?

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

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 bypass locks, float switches, leak sensors, or other safety systems.
Common causes include

- Moisture-related sensing issue on some models
Basic checks
- Stop the cycle if safe.
- Unplug only if it is safe and dry to do so.
- Check the model manual before retrying controls.
- Look for water rising higher than normal; if the tub or tray overfills, stop the cycle before another retry.
- Check visible hose routing for unusual siphoning; if water level changes unexpectedly, stop retries.
- Restart only after the visible water level looks normal; if the code returns, leave sensor checks to service.
Reset or retry steps
- If the model guidance suggests a brief unplug reset, retry once and stop if PE returns.
When to call a technician
