What PF
actually means.
The power to the dishwasher was interrupted. LG describes PF as a protection that follows an outage, and it can also point to a circuit too weak for the machine.

What to do when PF shows on the dishwasherKind of codeMode, not a failure
A setting someone turned on, or a reminder the machine shows on purpose — a control lock, a demo mode, a rinse-aid prompt. Nothing is broken and no part is needed.

After a local outage, press any button and allow about 10 seconds for the display to clear.

The door is shut and a cycle is chosen, but nothing happens, or the lights come on and it will not run.

Before you book,
in this order.
Each step comes from LG's own guidance for PF on its dishwashers. Follow it to the end: the last card says whether this is a visit.
After a local outage, press any button and allow about 10 seconds for the display to clear.
Make sure the dishwasher is on its own 15-amp, 120-volt grounded circuit with no extension cord.
If PF keeps showing without any outage, book a visit.
Cleared?
No part needed replacing. If the next full cycle still stops partway or leaves water in the tub, treat that as a new problem.
What not to do
Do not plug the dishwasher into an extension cord to move it to another outlet. LG rules that out, and it is a common reason PF keeps returning.
