Unlocking Solutions: How to Reset the LG Washer FE Error Code

The appearance of the FE error code on your LG washing machine is usually a result of the water level being too high during a cycle. This error is an abbreviation for “Filling Error,” indicating that your washer has encountered a challenge in managing water levels either during the wash or rinse cycle. In more technical terms, the pressure sensor frequency has surpassed 21.3 kHz, detecting an overflow of water.

This issue points to an anomaly in water management within the appliance, leading to the activation of the FE fault code.

FE Error Code on LG Washing Machines: Causes

Let’s break down these factors that can contribute to the FE fault code on an LG washing machine:

Adjusting Water Level Manually

  • Some users may believe that the washer hasn’t taken enough water for their load, so they manually add more water through the detergent drawer. This extra water can lead to the FE error code because the LG washer’s water level sensor is designed to automatically calculate and adjust the water required for each load. Adding water manually can disrupt this process.

Overloading the Washing Machine

  • Overloading the washing machine can lead to unexpected movement of the drum. This movement might cause the pressure sensor hose, which connects to the water level sensor, to disconnect. This disconnection can prompt the machine to display the FE fault code as it struggles to accurately determine water levels.

Stuck water inlet valve

  • If the water inlet valve becomes stuck in the open position, it continuously allows water to flow into the machine, causing an overflow. This overflow situation triggers the FE fault code because the pressure sensor detects an excess of water.

Pinholes in the pressure sensor hose

  • If there are pinholes or damage in the pressure sensor hose, it can’t maintain the necessary pressure to provide accurate water level readings. This can result in an erroneous FE error code.

Clogged air chamber

  • The air chamber is part of the pressure sensing system. If it becomes clogged with debris or foreign materials, it can’t function correctly, leading to inaccurate water level measurements and the potential for the FE fault code.

Faulty Pressure Sensor (Water Level Sensor)

  • The pressure sensor, also known as the water level sensor, is responsible for sending signals to the main board to control water levels. If it fails to send accurate signals or malfunctions, it can trigger the FE error.

Faulty Main Board

  • A faulty main control board can also be a culprit. If components like the water valve TRIAC or the IC responsible for sending and receiving signals from the pressure sensor are damaged or shorted, they can’t communicate properly with the water level sensor, resulting in the FE fault code.

Fixing LG Washer FE Error Code: Troubleshooting and Solutions

If the FE fault code appears on your LG washing machine, you can take the following troubleshooting steps to resolve the issue:

Avoiding the Incorrect Water Level Adjustment

  • If you’ve added wet laundry after the cycle has started, avoid manually adding more water. Instead, allow the machine to complete its cycle. For the best results, ensure all laundry is loaded before starting the cycle.

Avoid overloading the washing machine

  • To prevent the drum from moving excessively, avoid overloading the machine. Follow the manufacturer’s guidelines for maximum load capacity to maintain proper operation.

Rectifying a Jammed Water Inlet Valve

  • Check the water inlet valve for any obstructions or signs of being stuck. If necessary, clean or replace the valve to ensure it opens and closes properly during cycles.

Checking Pressure Sensor Hose and Connections

  • Inspect the pressure sensor hose for any visible damage or pinholes. If detected, replace the hose to restore accurate pressure readings.

Unclogging the Air Chamber for FE Error Code

  • Locate the air chamber and clean it of any debris or sediment that might be causing blockages. Clearing the air chamber will help the pressure sensor function correctly.

Differentiating Between Defective Stuck Water Inlet Valve and Shorted Water Inlet Valve TRIAC: Expert Tips

When it comes to troubleshooting issues with your washing machine, specifically differentiating between a defective stuck water inlet valve and a shorted water inlet valve TRIAC, these expert tips will guide you through the process:

Prepare the washing machine
  • Begin by turning off the washing machine and ensuring the water tap is firmly closed to prevent any water flow during the diagnostic process.
Test for a Stuck Water Inlet Valve
  • With the washing machine turned off, open the water tap.
  • Observe whether water enters the machine.
  • If water flows into the machine, it’s a clear indicator that the water inlet valve is stuck in the open position. This suggests the need for a replacement to restore proper functioning.
Test for a Shorted Water Inlet Valve (TRIAC)
  • If no water enters the machine during the previous step, turn on the washing machine without pressing the start/pause button.
  • Observe whether water starts entering the machine at this point.
  • If water begins to flow, it indicates a short circuit in the water inlet valve (TRIAC). This signals that the main board needs to be replaced to rectify the issue.
