If your Panasonic washing machine is failing to drain properly and displaying the U11 error on the control panel, fret not. Follow this guide to efficiently troubleshoot and resolve the issue.
What Does U11 Error Mean on Panasonic Washing Machines?
The U11 error is a prevalent issue with Panasonic washing machines. It occurs when water fails to drain or drains slower than usual towards the end of the washing cycle.
The U11 error notification appears once the washing cycle completes and the machine transitions to the spin mode. The error typically shows up fifteen to twenty minutes after the drainage process commences, while water remains trapped inside the machine.

Causes and Solutions for U11 Error on Panasonic Washing Machines
Here's a rundown of the most common causes and solutions for the U11 error on Panasonic washing machines:
Clogged Drainage System
This is one of the common issues leading to the U11 error on Panasonic washing machines. The drainage pipe may be bent or obstructed by a heavy object, causing a blockage and preventing water from draining properly.
If the drainage pipe is bent or flattened by a large object, it should be removed. Rectifying this situation can be done independently; simply monitor and inspect the drainage pipe regularly.
Additionally, prolonged accumulation of dirt in the pipes can also lead to blockages. Therefore, to prevent the U11 error message, regular cleaning and maintenance of the pipes are essential.
High or Excessively Long Drainage System
Even if the drainage pipe is installed incorrectly, water can still drain out if the pipe is too high or too long. However, this installation method is prone to dirt buildup and accumulation, leading to pipe blockage and improper drainage.

Clogged or Faulty Drain Valve
The U11 error on Panasonic washing machines can occur due to a clogged or faulty drain valve. This is because the drain valve is located inside the washing machine at the bottom of the drum; therefore, it may sometimes be obstructed by smaller-sized clothing items.
Before loading clothes into the washing machine to start the washing cycle, it's essential to develop a habit of continuously checking and inspecting the drain valve pipes. This is the simplest way to avoid this situation.
A Malfunctioning Motor for the Drainage System
The motor pull-out for Panasonic washing machines is typically a two-wire type powered by 220 volts. However, after a certain period of use or in case of incidents causing wire coil breakage, the motor will eventually cease to function.
You need to contact a highly skilled expert so they can inspect and troubleshoot the issue for you to ensure it is resolved.
Faulty Circuit Board
If you have attempted to troubleshoot the issue with each solution mentioned above but your Panasonic washing machine continues to display the U11 error, then the problem may lie with a defective or faulty main circuit board.
Under normal circumstances, the circuit board will supply 220V power to the washing machine's drain motor. However, due to some issues, the circuit board has been damaged and is unable to provide the washing machine with the appropriate 220V voltage.

You can use a VOM meter to check the power supply from the circuit board to the drain motor; if the power supply is not accurate at 220V, you will need assistance from reputable warranty centers or repair services.
