Understanding the PE Error: What Does It Mean?

So, what exactly does the PE error mean on your LG washer? Simply put, it usually indicates a problem with the pressure sensor or the pressure switch. This sensor is responsible for detecting the water level inside the drum. If it's malfunctioning, the washer might not fill correctly, overfill, or, you guessed it, refuse to spin because it doesn't know how much water is actually in there. Think of the pressure sensor as the washer's brain when it comes to water levels. It constantly monitors the pressure inside the drum to ensure the correct amount of water is added for each cycle. When this sensor malfunctions, it sends incorrect signals to the washer's control board, leading to a variety of issues, including the dreaded PE error. Several factors can cause a pressure sensor to fail. Sometimes, it's simply a matter of age and wear and tear. Over time, the sensor can become less sensitive or develop internal faults. Other times, external factors like power surges or water damage can compromise its functionality. In some cases, the pressure sensor itself is perfectly fine, but the problem lies in the wiring or connections leading to it. A loose or corroded connection can disrupt the signal flow, causing the control board to misinterpret the water level. Regardless of the specific cause, a malfunctioning pressure sensor will prevent the washer from operating correctly. It may fill with too much or too little water, fail to drain properly, or, as you're experiencing, refuse to spin. That's why troubleshooting the PE error often involves inspecting the pressure sensor, its connections, and the components related to water level control. By understanding the role of the pressure sensor and the potential reasons for its failure, you'll be better equipped to diagnose the problem and take the appropriate steps to resolve it. So, let's move on to the next section and explore some common causes of the PE error in LG washers.
