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
