What Does Error F3 Mean?

The LG washing machine error F3 signifies a problem with the water filling process, typically caused by issues with the water inlet valve or water level detection. This error can result in the machine stopping mid-cycle and may prevent it from starting due to prolonged fill times or failure to detect the correct water level. Common causes include insufficient water supply, a faulty inlet valve, or a malfunctioning water level sensor.

Common Symptoms:

  • Washing machine displays F3 and stops mid‑cycle
  • Water fill takes unusually long or fails
  • Washer does not start washing due to fill/level issue

Possible Causes

  • Insufficient or restricted water supply (closed tap, kinked hose, low water pressure) (medium)
  • Faulty or obstructed water inlet valve (medium)
  • Water level sensor/pressure switch malfunction or blockage (medium)
