If the sensor malfunctions or detects an abnormal water level, it will trigger the PE error, preventing the washer from proceeding with the spin cycle. Understanding the role of the pressure sensor is crucial to effectively troubleshooting this issue. It is responsible for detecting the water level inside the washer drum. If the sensor malfunctions or detects an abnormal water level, it will trigger the PE error, preventing the washer from proceeding with the spin cycle. Now that we know what the PE error means, we can delve deeper into the potential causes and how to address them.

The pressure sensor is a small, but important, component that monitors the water level inside the washer tub. It works by detecting the pressure exerted by the water. This information is then sent to the washer's control board, which determines whether the water level is appropriate for each stage of the wash cycle. When the pressure sensor fails to accurately detect the water level, it can send incorrect signals to the control board, leading to the PE error. Several factors can cause the pressure sensor to malfunction, including physical damage, electrical issues, or blockages in the pressure hose. Diagnosing and resolving these issues promptly is vital to restore your washer's functionality and prevent further damage.
