What This Means

PBA connector terminal not connected; Motor spin net not engaged; Motor internal coil damaged (short-circuited or cut); Hall sensor terminal not connected; Foreign material (e.g., a screw) entered the motor; Motor overloaded due to too much laundry (non-sensing); Motor hall sensor terminal not connected; PBA fault — weak motor driving signal or unstable relay operation; Erroneous operating signals from motor hall sensor; IPM terminal of Main PBA not connected; DD motor cover out of place; PCB housing terminal not connected; DD motor fault

What actually causes this:

The washer is overloaded with too much laundry, or something fell between the drum and tub

First Thing to Check

Reduce the laundry load — remove about half the items and restart the cycle
