How do I fix my Samsung washer when it displays the SE code?

The SE error code on a Samsung washer is an indication that there is a problem with the washing machine's door. The door sensor is located at the top of the door and is responsible for detecting whether the door is open or closed. If the door sensor is not working properly, it will cause the SE error code to appear. There are a few reasons why the door sensor may not be working properly. The most common reason is that the door sensor is dirty or has debris on it. This can be fixed by cleaning the door sensor with a cotton swab or a soft cloth. Another reason why the door sensor may not be working properly is that it is loose. This can be fixed by tightening the screws that hold the door sensor in place.
