Similar to many other washing machine models, Panasonic machines may encounter various operational issues. U12 error is frequently observed in Panasonic washing machines. However, many people are unaware of the optimal approach to address this error. The following article will provide detailed instructions on how to effectively troubleshoot this issue. Let's delve into it!
What is U12 error code in Panasonic washing machines?

This error code often occurs during the spin cycle. After the drain cycle, you may hear beeping sounds from the machine, and the U12 error code will appear on the display. U12 error is one of the common error codes on both top-loading and front-loading Panasonic washing machines.
Causes and simple solutions for resolving U12 error in Panasonic washing machines
Here are some causes and solutions when Panasonic washing machine displays U12 error simply:
Incomplete door closure
- This is a frequent cause of U12 error on Panasonic washing machines. This error typically occurs during the spin cycle when the door is not properly closed. This feature is integrated by the manufacturer to ensure user safety during high-speed spinning.

- To resolve this issue, simply check if the washing machine door is tightly closed. If not, just close the door tightly again.
Clothing jammed in the washing machine
- This happens when too many clothes are put in, exceeding the recommended limit by the manufacturer. The weight limit of clothes may vary depending on the size of the washing machine. Therefore, carefully refer to the instruction manual for the most accurate specifications.
- To fix this issue, check if any clothes are jammed inside the washing drum. If so, remove them to allow the machine to operate normally. Note: Avoid overloading the washing machine to save energy. Instead, divide the laundry into multiple loads to prevent U12 error from occurring.
Faulty door switch

- Another possible cause could be a malfunctioning door switch in the washing machine, leading to the U12 error on Panasonic machines. Even though you've checked and closed the door switch tightly, the contacts may still remain loose. Extended usage may result in oxidation of the switch, preventing electrical conduction and triggering the error.
- To address this issue, if you're not a technician, contact a reputable maintenance and repair center immediately. This ensures quality service for replacing the door switch for you.
Malfunctioning circuit board
After thoroughly checking all the above causes, if the washing machine still cannot resolve the U12 error, it may indicate a faulty circuit board. In such cases, refrain from attempting DIY dismantling and repair, as lack of expertise may worsen the issue. Instead, flexibly reach out to skilled and reputable technical specialists for timely and most effective assistance.
