When your LG washer displays a PE error code, it signals a problem with the water level sensor. This problem can bring your laundry routine to a sudden halt. In this article, we will explore what a PE error code means, its common causes, how to troubleshoot, and when to call in a professional.
A PE error code on an LG washer indicates a problem with the water level sensor. To fix it, first try resetting the washer by unplugging it and leaving it off for three to five minutes. If the error persists, inspect the wiring harness that connects the water level sensor to the main control board. If the error still appears, the water level sensor might be faulty and need replacement. If you’ve tried all these steps and the error code still appears, it’s time to call a professional.
Understanding a PE Error Code
A PE error code stands for “Pressure Error”. It indicates an issue with the water level sensor in your LG washing machine. The sensor’s job is to detect and control the water level in the washer. When the sensor malfunctions, it can’t accurately detect the water level, causing the washer to display a PE error code.
Common Causes of a PE Error Code
There are two main causes of a PE error code:
- Faulty Water Level Sensor: The sensor might be malfunctioning and unable to detect the water level accurately.
- Wiring Issue: There could be a problem with the wiring harness that connects the water level pressure sensor to the main control board.
How to Troubleshoot a PE Error Code
If your LG washer displays a PE error code, don’t panic. Here are some steps you can take to troubleshoot the issue:
Step 1: Reset the Washer
The first and simplest step is to reset the washer. Unplug the machine and leave it off for three to five minutes before turning it back on again. This simple reset can sometimes clear the error code.
Step 2: Inspect the Wiring
If the error code persists after resetting the washer, the next step is to inspect the wiring. Check the wiring harness that links the water level pressure sensor to the main control board. Ensure that the wiring harness is securely connected and has continuity.
Step 3: Check the Water Level Sensor
If the error code still persists after checking the wiring, the water level pressure sensor itself may be at fault. The sensor will need to be replaced if it’s faulty.
Preventing a PE Error Code
Regular maintenance of your LG washer can help prevent the occurrence of a PE error code. Here are some maintenance practices to follow:
- Regularly Inspect the Wiring: Check the wiring harness that connects the water level pressure sensor to the main control board. Ensure that the connections are secure and that there are no signs of damage or wear.
- Clean the Water Level Sensor: Over time, dirt and debris can accumulate on the water level sensor, affecting its performance. Regularly clean the sensor to ensure accurate readings.
- Schedule Regular Maintenance: Have a qualified technician inspect your washing machine periodically to ensure that all components are functioning correctly.
When to Call a Professional
If you’ve tried all the troubleshooting steps and the PE error code still appears, it’s time to call a professional. A qualified technician can inspect your washer, identify the problem, and fix it.
In conclusion, a PE error code on an LG washer indicates a problem with the water level sensor. While this can be a cause for concern, it’s not insurmountable. With proper troubleshooting and regular maintenance, you can keep your LG washer running efficiently.
Frequently Asked Questions
Where is the water level sensor located on an LG washer?
The water level sensor, also known as the pressure switch, is typically located at the back of the washer. It’s usually housed in a small compartment and connected to the drum with a thin hose. However, the exact location may vary depending on the model of your LG washer.
How often should I clean the water level sensor?
It’s a good practice to clean the water level sensor every six months to ensure it functions properly. However, if your washer is frequently giving a PE error code, you may need to clean it more regularly.
Can I replace the water level sensor myself or do I need a professional?
While it’s possible to replace the water level sensor yourself, it’s recommended to hire a professional if you’re not comfortable with appliance repair. The process involves disassembling parts of the washer, which can be complex and risky if not done correctly.
What are some common signs of a faulty water level sensor?
Apart from the PE error code, a faulty water level sensor might cause your washer to overfill, underfill, or have an irregular filling pattern. It may also cause the washer to not start, stop in mid-cycle, or fail to drain properly.
How much does it cost to replace a water level sensor in an LG washer?
The cost of replacing a water level sensor can vary depending on the model of your washer and the rates of the technician. On average, you can expect to pay between $50 and $100 for the part, plus labor costs.
