What Does Error LF Mean?

The Whirlpool Washing Machine LF error indicates a long fill condition, meaning the washer is unable to fill with water within the required timeframe. This may be due to insufficient water supply, clogged hoses, or a faulty water inlet valve. When this error occurs, the machine may also start draining or lock the lid, preventing operation until the issue is resolved.

Common Symptoms:

  • Incorrect drain hose installation causing siphoning (medium)
  • Clogged inlet hose filters or hoses restricting flow (medium)
  • Faulty water inlet valve not letting enough water in (medium)
  • Faulty water level/pressure sensor (medium)
