While using your washing machine, encountering the U12 error from Panasonic but unsure of the cause? This Mytour article provides answers to the Panasonic washing machine U12 error and how to fix it.
What is the U12 error in Panasonic washing machines?

When switching to the wringing mode and pulling the lever for 3 – 5 seconds, the washing machine will indicate U12 error. This error signals that the washing machine lid is still open, not closed tightly, or something is stuck, preventing the lid from closing properly.
Causes of Panasonic washing machine U12 error

Washing machine lid not properly closed
Panasonic washing machines often encounter the U12 error during use. This error notification usually occurs when using the wringing mode and the door is not tightly closed. This is integrated to ensure user safety when the machine is operating at high speeds. Understanding the cause and this feature will help Panasonic washing machine users handle the U12 error appropriately.
Faulty door switch or circuit board
The U12 error on Panasonic washing machines can also be caused by a malfunction of the door switch. Even if you have closed the door switch tightly, open contacts can cause the U12 error. If the switch has been in use for too long, it may oxidize, and current cannot pass through, leading to the error. If after checking all the above reasons, the washing machine still reports the U12 error, the cause may be a malfunctioning circuit board.
How to troubleshoot U12 error on Panasonic washing machine

All the above reasons can lead to the U12 error on Panasonic washing machines, causing the machine to stop working while in the wringing mode. Users need to carefully check these factors and make repairs to fix the error on the washing machine.
For cases where the machine reports an error due to an open door or improperly closed door, users can fix it themselves.
It is not advisable to repair a Panasonic washing machine U12 error caused by a faulty door switch or circuit board on your own. Fixing this error requires knowledge of electricity and electronics, and without experience, users may cause serious damage to the machine.
Instead, when the machine indicates the U12 error, users should check the machine's warranty information and contact the Panasonic warranty center if the machine is still under warranty. If the warranty has expired, users can call a reputable washing machine repair service to have the machine inspected and the error resolved.
Other common error codes in Panasonic washing machines

Panasonic washing machine reports U13 error
One reason for the Panasonic washing machine reporting U13 error is imbalance during the washing process. This can happen when clothes are unevenly distributed in the drum or when the washing machine is tilted or uneven on the floor.
To resolve the U13 error, users need to evenly distribute clothes in the drum and adjust the washing machine for balance when placed on the floor, then open and close the lid to make the machine operate.
Panasonic washing machine reports U11 error
This is a drainage error. The main causes of the U11 error on Panasonic washing machines can be a clogged or twisted water drainage pipe. Additionally, if the pipe's end is too high compared to the standard level or if the filter slot at the pipe's end attached to the washing machine is blocked, it can also cause this error.
To troubleshoot, users need to check the water drainage pipe for any clogging or twisting. If it is positioned too high, you need to lower the drainage pipe. Additionally, check the water filter slot for any blockage. If necessary, you can also remove the filter slot for cleaning or replacement.

Panasonic washing machine reports U14 error
The causes of the U14 error – water not entering the washing machine – include weak water pressure, the water tap not being opened, or the water filter mesh being blocked.
To address this situation, check water pressure and use an automatic booster pump if necessary. Ensure that the water tap is open and clean the water filter mesh to avoid clogging with dirt. This will ensure that water can enter the washing machine, allowing you to carry out the laundry process efficiently and conveniently.
Panasonic washing machine reports H01 error
The causes of the H01 error can be a malfunctioning pressure switch, a faulty circuit board, or a broken wiring from the pressure switch to the circuit board.
The remedy for these situations is to replace the sensor switch. Check the wiring from the pressure switch to the electronic circuit board, if broken, reconnect the wires according to the correct colors or call a washing machine repair expert.
