LG Dishwasher PF error code

Difficulty: Easy · Cost: $0 · Duration: 2–5m

The PF code means your LG dishwasher detected a power interruption during a running cycle. This is a protective feature designed to alert you that the cycle did not complete normally. It can be caused by a local power outage, a tripped circuit breaker, or an inadequate power supply. The dishwasher must be connected to a dedicated circuit at 120V, 60Hz with a minimum of 15 amps — sharing a circuit with other appliances or using an extension cord can cause repeated PF codes.

Common causes

  • Power outage interrupted the cycle while the dishwasher was running
  • Circuit breaker tripped due to insufficient electrical capacity
  • Dishwasher is sharing a circuit with other appliances overloading it
  • Extension cord is being used instead of a direct wall connection
  • Dishwasher is not properly grounded

How to fix it

  1. 1

    Press any button on the control panel to clear the PF code — it may take up to 10 seconds to clear

  2. 2

    Make sure the dishwasher is connected to a dedicated circuit breaker at 120V, 60Hz with a minimum of 15 amps

  3. 3

  4. 4

  5. 5

    If PF appears repeatedly during normal use without a power outage have an electrician check the circuit capacity
