Pe Error Code Meaning
The PE error code on an LG washing machine shows a problem with the water level sensor. This sensor is also called the pressure switch. It tells the machine how much water is inside. When the sensor does not work right, the machine shows the PE error code. This error stops the washing cycle until the issue is fixed.
Understanding the meaning of the PE error code helps in quick troubleshooting. It points to a fault in sensing the water level. This can cause the machine to overfill or not fill enough. Fixing this error ensures the washer works safely and correctly.
What Pe Error Indicates
The PE error means the pressure switch has a fault. This switch measures water pressure inside the tub. It sends signals to the machine’s control board. If the pressure switch fails, the machine cannot detect water level properly. The washer then stops and shows the PE code. This prevents damage from too much or too little water.
Common Causes
Blockages in the pressure tube are a usual cause. The tube links the water tub to the pressure switch. Dirt, detergent, or debris can clog this tube. A blocked tube stops the switch from sensing water pressure. Another cause is a damaged or faulty pressure switch. Wiring problems can also trigger the PE error. Loose or broken wires affect communication between parts.
Initial Troubleshooting
The LG washing machine PE error code signals an issue with the water level sensor. Initial troubleshooting helps identify simple problems before calling for repairs. These steps often fix common causes quickly.
Start by resetting the power. Then inspect the pressure tube for blockages. These actions clear many faults causing the PE error.
Power Reset Steps
Unplug the washing machine from the power outlet. Wait for about one minute to allow the system to reset. Plug the machine back in and turn it on. Check if the PE error still appears. This reset can clear temporary faults in the control board or sensors.
Inspecting The Pressure Tube
Locate the thin pressure tube inside the washing machine. It connects the tub to the pressure switch. Check the tube for any kinks, bends, or blockages. Dirt, detergent, or lint can clog the tube and affect sensor readings. Clear the tube by gently blowing air through it. Make sure it is properly reattached and not damaged. A clean and intact tube helps the sensor detect water levels correctly.
Cleaning And Inspection
Cleaning and inspection are key steps to fix the LG washing machine PE error code. Dirt or blockages can cause the pressure switch to give wrong readings. Careful cleaning and checking ensure the machine works properly again. This section guides you through cleaning the pressure switch and checking wiring connections.
Cleaning The Pressure Switch
Unplug the washing machine before starting. Locate the pressure switch inside the machine. It connects to a thin air tube. Detergent or dirt can block this tube. Gently remove the tube and clear it by blowing air through it. Wipe the pressure switch with a soft cloth. Do not use water or harsh cleaners. Reattach the tube securely after cleaning. This helps the switch sense water levels correctly.
Checking Wiring Connections
Turn off the power to the machine. Open the back panel to access wiring. Look for loose or damaged wires near the pressure switch. Firmly reconnect any loose wires. Replace wires if they appear worn or broken. Check the wiring harness for corrosion or dirt. Clean connectors carefully with a dry cloth. Proper wiring ensures clear signals from the pressure switch. This step prevents false PE errors.

Testing And Replacement
Testing and replacement are key steps to fix the LG washing machine PE error code. This error often points to a problem with the pressure sensor. Checking the sensor’s function can save time and money. Knowing when to replace the sensor helps avoid recurring errors and damage.
Testing The Pressure Sensor
Start by unplugging the washing machine to stay safe. Find the pressure sensor, usually near the water tub. Detach the air tube connected to the sensor carefully. Blow gently into the tube to check for blockages. A blocked tube can cause wrong readings and trigger the PE error.
Use a multimeter to test the sensor’s electrical resistance. Set the meter to the ohms setting. Connect the meter probes to the sensor terminals. Watch for a change in reading when you apply air pressure to the tube. No change means the sensor may be faulty. Clean the sensor and tube again if needed and retest.
When To Replace The Sensor
Replace the sensor if cleaning and testing do not fix the error. A sensor that shows no resistance or no change during testing is broken. Also, replace it if the washing machine still shows the PE code after troubleshooting. Using a faulty sensor can cause water level problems and damage the machine. Installing a new sensor ensures proper water level detection and smooth operation.
Always use original or compatible LG parts for replacement. Follow the user manual or get help from a professional technician. Correct replacement keeps the washing machine safe and reliable.
Advanced Troubleshooting
Advanced troubleshooting helps fix persistent LG washing machine PE errors. Simple resets may not solve all problems. Checking the machine deeper reveals hidden issues. Understanding key parts and their functions aids repair.
Pressure sensors and tubes often cause PE errors. Dirt, blockages, or damage stop them from working. Thorough inspection and cleaning improve machine performance. Sometimes, replacing parts is necessary for long-term fix.
Handling Blockages And Kinks
Start by unplugging the washing machine for safety. Locate the air pressure tube connected to the pressure switch. This thin tube can get blocked or bent.
Remove any visible dirt or detergent build-up inside the tube. Use a soft brush or blow air gently to clear it. Straighten any kinks to allow smooth air flow.
Inspect the pressure switch for dust or water damage. Clean it carefully with a dry cloth. Avoid using water or harsh chemicals on the sensor.
After cleaning, reconnect all parts and power on the machine. Check if the PE error persists. Repeat cleaning if needed or consider replacing the tube or sensor.
