1. Inspect the Pressure Hose

Okay, first things first, let's check that pressure hose, guys. The pressure hose connects the pressure sensor to the washer drum, and if it's blocked or kinked, it can cause all sorts of problems. Start by locating the hose, usually found at the top or back of the washer. Disconnect it from both the pressure sensor and the drum. Inspect the hose for any visible kinks, cracks, or blockages. If you find any debris inside, try blowing it out or using a small brush to clear it. Once you've cleared any obstructions, reconnect the hose securely and ensure it's not kinked. Then, run a test cycle to see if the PE error is resolved. If the error persists, move on to the next step. This simple check can often resolve the issue, especially if the washer has been in use for a long time and debris has accumulated in the hose. Regularly inspecting and cleaning the pressure hose can help prevent future occurrences of the PE error.

2. Check the Pressure Sensor

Next up, let's take a peek at the pressure sensor itself. The pressure sensor is responsible for detecting the water level in the washer drum, and if it's not working correctly, it can trigger the PE error. To check the pressure sensor, you'll need a multimeter. Disconnect the sensor from the washer and use the multimeter to test its resistance. Refer to your washer's service manual for the correct resistance values. If the sensor's resistance is outside the specified range, it's likely faulty and needs to be replaced. Replacing the pressure sensor is a relatively straightforward process, and you can usually find a replacement part online or at your local appliance parts store. Once you've replaced the sensor, run a test cycle to see if the PE error is gone. If it's still there, don't worry; we've got more steps to try! Ensuring the pressure sensor is functioning correctly is crucial for accurate water level detection and proper washer operation. This step will help you identify whether the sensor itself is the source of the problem.
