A:
I think you mean LF code. If so see below:
LF flashes when the water level does not change for a period of time after the valves are turned on OR water has disengaged the basket but control does not detect a water level change.
Is water supply connected and turned on?
Are hose screens plugged?
Is water entering the tub? If so check pressure hose connection to machine/motor control.
See TEST #2.
