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.
- Stop and address visible water before retrying the appliance.
- 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
- Lint or debris restricting the owner-accessible drain filter
- The visible drain hose is kinked, compressed, or obstructed
- A drain-path condition that requires qualified inspection
Basic checks
- Record U11 and wait for all drum movement to stop; if water remains visible, keep the door closed and do not start another wash programme.
- Inspect only the exposed drain hose without pulling out or tilting the washer; correct a simple visible kink, but stop for damage, leakage, or hidden access.
- Follow the exact NA-V10FR1WAU manual's drain-filter procedure only after disconnecting power from a dry position, letting hot water cool, and preparing the specified controlled drainage tray.
- Confirm that the filter is fully reinstalled and the floor, plug, and outlet area are dry before considering one monitored drain attempt.
Reset or retry steps
- Press Start once only after a safely corrected visible restriction or completed exact-manual filter check, with no leak and no water near electrical parts.
- Stop further attempts if U11 returns or water remains; repeated starts are not a repair and hidden pump or wiring checks belong to qualified service.
When to call a technician
- Contact Panasonic service if U11 remains after the exact-manual owner checks, the filter cannot be reached safely, or the washer still does not drain on the single monitored attempt.
- Arrange urgent qualified help if water leaks, cannot be contained, approaches the cord or outlet, or the door remains locked with water visible.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ
What does Panasonic Washer code U11 usually mean?
Panasonic New Zealand documents U11 on washer model NA-V10FR1WAU as unable to drain. Model context matters: The NA-V10FR1WAU manual pairs its unable-to-drain display with a lint check and the owner-accessible drain-filter procedure on page 34.
Can I keep using the washer with code U11?
Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. Retained wash water may be hot; never force the door, open the filter while powered, or release water without the exact manual's controlled drainage setup.
When should I call a technician for Panasonic U11?
Contact Panasonic service if U11 remains after the exact-manual owner checks, the filter cannot be reached safely, or the washer still does not drain on the single monitored attempt. A qualified technician may check Drain filter, Drain hose, and Drain-pump system against the model's service information before treating any part as failed.
