Frequently Asked Questions


Why does my Panasonic Washer show ERR or system error messages?
System errors usually indicate temporary faults such as power fluctuations, sensor issues, or communication errors. Turn off the washer, unplug it for a few minutes, then restart. If the issue continues, check water supply, drainage, and load balance.
Why does my Panasonic Washer display LOCK or child lock?
LOCK means the control panel is locked for safety. Press and hold the lock or child-lock button for a few seconds to disable it. If it does not respond, restart the washer and try again.
Why does my Panasonic Washer show HOT or overheating warning?
HOT indicates the internal system or water temperature is too high. Stop the cycle, turn off the washer, and allow it to cool. Make sure ventilation is clear before restarting.
Why does my Panasonic Washer show PF (power failure)?
PF appears after a power outage or unstable voltage. Check the outlet and circuit breaker, then reset the washer and reconfigure settings if needed.

RESET means the system needs a reboot. Turn off the washer, unplug it for 5–10 minutes, then plug it back in to clear temporary system faults.
Why does my Panasonic Washer keep stopping mid-cycle?
This may be caused by unbalanced load, water supply issues, or drainage blockage. Redistribute clothes evenly, check hoses, and restart the cycle.
