Panasonic Washing Machine Error Codes: Complete List and How to Fix Them

Panasonic Washing Machine Error Codes Explained

Panasonic washing machines use a U-code and F-code system. U-codes are typically user-fixable issues (water supply, drain, balance), while F-codes usually indicate component faults requiring a technician. Here’s the complete list for Panasonic front-load and top-load models sold in India.

Panasonic Error Code Reference Table

Code Meaning DIY Fix?
U1 / U11 Water inlet problem — machine not filling Yes
U2 / U12 Drainage problem — water not draining Yes
U4 Unbalanced load — redistribute clothes Yes
U13 Water leak detected No
F1 Water level sensor fault No
F4 / F40 Water heater fault No
F7 Motor / speed sensor fault No
F11 Motor lock — drum not rotating Sometimes
H1 / H11 Door lock problem Sometimes
F20 NTC temperature sensor fault No

Step-by-Step Fixes

U1 / U11 — Water Not Filling

  1. Ensure the water supply tap is fully open.
  2. Check the inlet hose for kinks or damage.
  3. Turn off the tap, disconnect the inlet hose, and clean the mesh filter inside the hose fitting under running water.
  4. Confirm water pressure is adequate — Panasonic requires 0.05–0.8 MPa.
  5. Reconnect and restart. Persistent U1 after these steps indicates a faulty inlet valve.

U2 / U12 — Water Not Draining

  1. Access the drain pump filter at the bottom front of the machine.
  2. Place towels and a tray, then slowly remove the filter cap — water will flow out.
  3. Remove lint, coins, and debris from the filter and pump chamber.
  4. Check the drain hose for kinks and ensure the drain outlet isn’t blocked or submerged too deep (max 10 cm in the drain pipe).
  5. Reinstall the filter firmly and test with a drain cycle.

U4 — Unbalanced Load

  1. Open the door and redistribute clothes evenly in the drum.
  2. For bulky items like bedsheets, add 2–3 lighter items to balance the load.
  3. Verify the machine is level — check with a spirit level on top of the machine. Adjust leg levellers as needed.
  4. Close the door and press Start to resume spinning.

H1 / H11 — Door Problem

  1. Open the door, ensure no clothing is caught in the seal, and close it firmly.
  2. Reset by unplugging for 5 minutes.
  3. If H1 persists with the door properly closed, the door lock switch needs replacement.

F11 — Motor Lock

  1. Reduce the load — overfilling can lock the motor.
  2. Check for foreign objects in the drum (coins, buttons).
  3. Let the machine rest for 30 minutes to cool, then retry.
  4. If F11 appears on an empty drum, call Panasonic service.

Frequently Asked Questions

My Panasonic shows U2 but the drain hose looks fine — what next?

Clean the drain pump filter at the bottom of the machine. Lint buildup in the filter is the most common cause of U2, even when the drain hose itself is clear.

Panasonic keeps showing U4 unbalanced even after redistribution — why?

Check that all four machine legs are firmly on the floor and the machine is level. An unlevel Panasonic will trigger U4 repeatedly during spin cycles regardless of how the load is arranged.
