What Is Pe Code
The PE code on an LG washer signals a problem with the door lock. This error stops the machine from running. The washer will not start or complete cycles until the issue is fixed. Understanding the PE code helps you solve the problem fast. It saves time and avoids repair costs.
Meaning Of Pe Code
The PE code stands for “Pressure Error.” It means the washer detects a problem with the door locking system. The door must lock properly to keep water inside during a wash cycle. If the door lock sensor fails, the washer shows the PE code. This code warns that the door is not secure.
Common Causes
The PE code often happens because of a faulty door lock. The lock may be broken, loose, or dirty. Another cause is a wiring problem between the door lock and the control board. Sometimes, the control board itself may have an error. Water leaks or pressure sensor issues can also trigger the PE code. Checking these parts helps find the cause quickly.
Check Water Supply
Checking the water supply is a key step to fix the PE error code on your LG washer. Water flow problems often cause this error. Ensuring the washer gets enough clean water can solve the issue quickly.
Start by looking at the water hoses and then check the water pressure. Both affect how water reaches your washer.
Inspect Water Hoses
Look at the water hoses connected to your washer. Make sure they are not twisted or bent. Twists can block water flow. Check for leaks or cracks on the hoses. Replace any damaged hose right away. Also, confirm the hose ends are tightly connected to the water supply and washer. Loose connections cause low water flow and errors.
Verify Water Pressure
Water pressure must be strong enough for the washer to fill properly. Low pressure can trigger the PE error. Test the water flow from your tap. Open it fully and see if water flows fast and steady. If the flow is weak, call a plumber or your water company. They can check and fix your home’s water pressure. Proper water pressure helps your washer work without errors.
Reset The Washer
Resetting your LG washer is a simple step that can clear the PE error code. This code often appears because of a communication problem inside the washer. Resetting helps the machine start fresh and may fix the issue without needing a repair. Follow the instructions carefully to reset your washer safely and correctly.
Power Cycle Steps
First, unplug your LG washer from the power outlet. Wait for about 5 minutes to let the machine fully turn off. During this time, the internal system resets itself. After waiting, plug the washer back in. Turn the washer on and check if the PE code still appears. This power cycle can solve minor electronic glitches causing the error.
When To Reset
Reset your washer after a sudden power outage or error code display. If the PE code shows up during or after a cycle, try resetting first. Avoid resetting multiple times in a row without checking the washer’s parts. Use reset as an early step before calling a technician or inspecting the washer deeper.

Clean Water Inlet Valve
The water inlet valve controls water flow into your LG washer. Dirt and debris can block the valve. This causes the PE error code. Cleaning the valve often solves the problem. It is a simple task you can do at home.
Locate The Valve
Unplug the washer first to stay safe. Find the water inlet valve at the back of the machine. It is where the water hoses connect. Usually, it has a small screen to catch dirt. Check your user manual if you cannot find it.
Cleaning Procedure
Turn off the water supply before removing hoses. Unscrew the hoses from the valve gently. Look inside the valve’s screen for dirt or buildup. Use a small brush or cloth to clean the screen. Rinse the screen under running water to remove all debris. Reattach the hoses tightly to avoid leaks. Turn on the water supply and plug the washer back in.
Replace Faulty Components
Replacing faulty components is a key step in fixing the PE error code on your LG washer. Sometimes, worn or broken parts cause the error and stop the machine from working properly. Changing these parts can bring your washer back to life.
It’s important to identify which parts need replacement. This helps avoid extra costs and ensures the repair is effective. With the right parts, your washer will run smoothly again.
When To Replace Parts
Replace parts when the error code appears often. If the washer stops during cycles, parts might be faulty. Strange noises or vibrations also signal a problem. A part that looks damaged or worn should be changed. Regular checks help catch problems early.
Common Parts To Replace
The most common parts causing the PE error are the door lock, wiring harness, and control board. The door lock can fail to secure the door properly. Wiring harnesses may have loose or broken wires. The control board controls the washer’s functions and can get damaged. Replacing these parts often fixes the PE error.
Prevent Future Pe Errors
Preventing PE errors on your LG washer saves time and stress. These errors often come from drainage or sensor issues. Regular care and smart use help keep your washer running smoothly. Follow simple steps to avoid future problems and keep your laundry day easy.
Regular Maintenance Tips
Clean the drain pump filter every month. It stops blockages that cause PE errors. Check the drain hose for bends or kinks. Straighten it to ensure water flows out easily. Remove any dirt or debris from the hose. Run a cleaning cycle with vinegar or washer cleaner. This helps clear buildup inside the machine. Inspect the washer drum for objects stuck inside. Small items can block the drain and cause errors.
Proper Usage Practices
Do not overload the washer with clothes. Too many items block water drainage. Use the right amount of detergent. Excess soap causes extra suds and clogs. Always sort laundry by fabric type and weight. Heavy items can unbalance the washer during spin. Make sure to close the door properly before starting. A loose door can trigger error codes. Follow the user manual instructions for each wash cycle.
