Understanding the Mechanics of a Master Reset
Before performing the reset, it is helpful to understand what is happening inside your machine. Modern LG washers, both front-load washing machine and top-load washing machine models, are sophisticated appliances driven by computers. They utilize a main control board that acts as the brain of the operation, coordinating the motor, water valves, and sensors.

Like any computer, these boards can experience software glitches or get stuck in a logic loop. When you simply press the Power button to turn the machine off, the internal capacitors on the control board retain an electrical charge. This keeps the memory active for a short period. A hard reset forces this charge to dissipate completely, wiping the short-term memory and clearing out any “ghost” errors that may be confusing the system.
How to hard reset LG washer: Step-by-Step Guide
If your washer is acting erratically, follow this strict procedure. This method is universally applicable to most LG models. Please ensure you follow the timing instructions carefully, as rushing the process may result in an incomplete reset.
Step 1: Power Down and Disconnect
First, ensure the washer is turned off. Press the Power button on the control panel. Once the display goes dark, you need to completely disconnect the machine from its power source.
- Option A: Unplug the power cord from the wall outlet. This is the most direct method.
- Option B: If the outlet is difficult to reach, locate your home’s electrical panel and flip the circuit breaker assigned to the laundry room to the “OFF” position.
Step 2: Dissipate the Electrical Charge
This is the most critical step that many users overlook. With the machine unplugged, the internal capacitors still hold power. To drain this power:
- Press and hold the Start/Pause button for exactly 5 seconds.
- Next, press and hold the Power button for exactly 5 seconds.
By holding these buttons while the machine is disconnected, you are completing a circuit that attempts to draw power, thereby draining any residual energy stored in the main control board.
Step 3: Restore Power
After completing the button-holding sequence, plug the power cord back into the outlet or flip the circuit breaker back to the “ON” position. You may hear a click or see lights flash briefly on the control panel; this is normal.
Step 4: Verification
Turn the washer on. Before running a full load with clothes, you need to verify that the reset was successful. Select a “Rinse & Spin” or “Drain and Spin” cycle to test the machine’s basic functions. If the washer completes this short cycle without throwing an error code, the hard reset was successful.
Common Scenarios Resolved by a Hard Reset
Appliance troubleshooting often requires identifying symptoms before applying a cure. While a hard reset is a “catch-all” solution, it is particularly effective for the following specific issues.
The Non-Responsive Control Panel
Sometimes the washer has power, but the control panel refuses to respond to touch or button presses. This often mimics a “Child Lock” scenario, but if disabling the child lock does not work, the software is likely frozen. A hard reset re-initializes the user interface drivers, restoring touch sensitivity and button responsiveness.
Mid-Cycle Stoppage
If your washer stops abruptly in the middle of a cycle with water still in the drum, it can be alarming. This usually occurs due to a sensor miscommunication. Resetting the machine clears the current cycle’s programming. Note: If the machine is full of water, the door usually remains locked for safety. You may need to manually drain the water using the emergency drain hose (usually located behind a small door on the bottom front of front-load models) before the reset allows the door to unlock.
Persistent Error Codes
LG washers use a variety of error codes to communicate malfunctions. While some indicate genuine hardware failures, many are triggered by momentary sensor glitches.
- LE Code: Often indicates a motor overload, but can be a false flag due to a power surge.
- UE Code: Indicates an unbalanced load. If rebalancing the clothes doesn’t clear the code, a reset is necessary.
- OE Code: Indicates a drain issue. After checking the filter, a reset helps the sensor recognize that the blockage is gone.
- DE Code: Door error. If the door is shut but the code persists, the control board may just be confused about the latch status.
Front-Load vs. Top-Load Considerations
While the core mechanics of “How to hard reset LG washer” remain consistent, the physical design of the machine can influence how you approach the process.
Front-Load Washing Machine Specifics
Front-loaders are heavily reliant on the door latch assembly. The main control board performs a safety check on the door lock immediately upon startup. If you perform a hard reset on a front-loader, pay close attention to the clicking sound of the door lock engaging and disengaging when you plug it back in. If the reset fails to resolve a generic error, and you do not hear the lock engage, the issue is likely a hardware failure in the door latch assembly rather than a software glitch.
Top-Load Washing Machine Specifics
Top-loaders utilize a lid switch and often have more complex suspension systems. When resetting a top-loader, it is crucial to ensure the lid is completely closed during the power-up phase. Some modern top-load models calibrate the weight of the laundry immediately after a reset. If you initiate a cycle after the reset, do not interrupt the “sensing” phase (where the drum rotates back and forth), as this sets the baseline for the load balancing logic.
When a Hard Reset Doesn’t Work: Troubleshooting Hardware
If you have followed the guide on how to hard reset LG washer units faithfully but the problem persists, you are likely dealing with a hardware component failure. At this stage, the issue moves beyond simple software glitches.
Inspecting the Power Supply
Before calling a technician, inspect the power cord for any signs of damage, fraying, or burn marks. Ensure the outlet itself is providing consistent voltage. Washer control boards are sensitive to voltage fluctuations; if your home has unstable power, the washer may require a dedicated surge protector to prevent the board from freezing up repeatedly.
The Main Control Board
The main control board is the most expensive component to replace. If the washer behaves erratically—such as flashing random lights, starting cycles on its own, or failing to power on despite receiving electricity—the board itself may be damaged. A hard reset cannot fix physical damage to the circuit board, such as blown capacitors or soldered connections that have vibrated loose.
Motor and Sensor Issues
If a specific error code returns immediately after the reset (within seconds of powering on), the sensor associated with that code is likely disconnected or broken. For example, if the LE code returns instantly, the Hall sensor on the motor stator is likely the culprit. If the OE code returns immediately, the drain pump or the water level pressure switch should be investigated.
Safety Precautions During Troubleshooting
When dealing with appliance troubleshooting, safety must be your priority. Washing machines combine high-voltage electricity with water, creating a potentially hazardous environment.
- Dry Hands: Never touch the power cord or the circuit breaker with wet hands.
- Water Management: If you are resetting the machine because it won’t drain, be prepared for water spillage if you open the filter or the door manually. Have towels ready to prevent water from reaching the electrical outlet.
- Wait Times: When unplugging the machine, always wait the full recommended time. Plugging the machine back in too quickly can cause a power spike that might damage the sensitive electronics on the control board.
Preventive Maintenance to Avoid Glitches
To minimize the frequency with which you need to perform a hard reset, consider these maintenance tips:

- Avoid Overloading: Stuffing the washer puts strain on the motor and the suspension sensors, causing logic errors.
- Clean the Filter: A clogged drain filter is the number one cause of drain-related sensor errors. Clean it monthly.
- Use High-Efficiency Detergent: Excess suds can confuse the pressure sensors and block the air chamber in the water level switch, leading to false error codes.
- Monthly Tub Clean: Run the “Tub Clean” cycle with a proper cleaning agent to keep sensors free of grime and residue buildup.
Conclusion
Knowing how to hard reset LG washer models is a fundamental skill for maintaining your appliance’s health. It acts as the “Ctrl+Alt+Delete” for your laundry room, clearing out transient faults and restoring the machine to its default operational state. By correctly manipulating the power button, start/pause button, and power source, you can dissipate the electrical charge that holds onto corrupted memory.
However, remember that a hard reset is a diagnostic tool as much as it is a repair method. If the reset works, you have saved time and money. If the reset fails, you have successfully narrowed down the problem to a physical component, providing valuable information to a technician. Whether you own a sleek front-load washing machine or a high-capacity top-load washing machine, this simple procedure ensures you remain in control of your laundry routine.
Frequently Asked Questions
What is the difference between turning the washer off and performing a hard reset?
Simply turning the washer off and on does not clear the internal memory because the control board’s capacitors retain an electrical charge. A hard reset involves disconnecting the power and manually draining that residual energy, which wipes temporary software glitches and “ghost” errors that a standard restart cannot fix.

How long should I hold the buttons during the reset procedure?
After unplugging the machine or flipping the circuit breaker, you should press and hold the Start/Pause button for exactly 5 seconds, then press and hold the Power button for another 5 seconds. This specific timing ensures that the internal electrical charge is fully dissipated.
Which specific error codes can a hard reset potentially resolve?
A hard reset is particularly effective for clearing codes triggered by momentary sensor glitches, such as LE (motor overload), UE (unbalanced load), OE (drain issue), and DE (door error). If the code returns immediately after the reset, it likely indicates a physical hardware failure rather than a software loop.
Can I perform a hard reset if my front-load washer is full of water?
Yes, but you must be cautious. If the machine is stuck mid-cycle with water in the drum, the door will usually remain locked for safety. You may need to use the emergency drain hose (located behind the small door on the bottom front) to remove the water before the control board will allow the door to unlock after the reset.
What does it mean if the hard reset doesn’t fix the issue?
If you have followed the reset steps and the washer continues to act erratically or displays the same error code, you are likely dealing with a hardware component failure. Common issues that a reset cannot fix include a damaged main control board, a faulty door latch, or a broken motor sensor.
