LG Dishwasher FE / AE (RE) error code

Difficulty: Hard · Cost: $80–$200 · Duration: 5m

The FE error means your LG dishwasher detected an overfill — more water entered the tub than expected. As a safety measure the drain pump activates automatically to remove the excess water. This is usually caused by a faulty water inlet valve that is not closing properly and allowing water to keep flowing in. A power reset using the circuit breaker clears it in many cases. If FE keeps returning the water inlet valve will need to be inspected and replaced by a technician.

Common causes

  • Water inlet valve is faulty and not closing properly allowing continuous water flow
  • Water pressure from the household supply is too high
  • Temporary electronic glitch causing a false overfill reading

  5. 5
