Hi Guys,

We have a LG front load washer, about 10 years old. Getting PF error when washer goes though mid cycle and powers off. Seems power is getting to washer. Not sure what to check or replace. Is it the main power control board? Is this a common issue at this age?

Thanks

Here's the service manual: https://drive.google.com/file/d/1CCxITpTSlAkHOm0OOYZYG7gfVzy_M7vU/view?usp=share_link

I've not run into this issue before on this model, do you unplug the machine and plug it back in within 5 minutes to reset it and make it work again?

Its possibly a problem in the main control board, or a loose wire harness connection at the main control board.

Here's the PCB Assembly(aka main control board) for your model, if needed:
