When it gives the error, is there ample water in the tub?
May I please have your complete model number so I am able to provide you with accurate, model specific information?
It should be on a tag under the lid or behind the door around the opening.
Please allow me just a few minutes to prepare some information for you, thank you!
The pressure sensor, number 23in the diagram at the link below, is likely having issues. Access it by removing the screws from the back of the top panel and slide the top off. Remove the hose from the pressure switch and blow through it (the hose). If air easily passes, replace that pressure switch.

Is the tube clear? Can you blow through it?
Okay, so that is clear. As the water fills, the air pressure rises in that tube to the pressure switch. In turn, the pressure switch tells the main control what the water level is doing.
If you have replaced the pressure switch, either the message is not getting to the control from it or the control is not processing it correctly. The LF means that the control is not "seeing" the water level rising.
Well, if the pressure switch is new and you are certain the wiring between the pressure switch and the control is good, then the control is likely faulty. Return the pressure switch and replace the main control.
The other end of the hose connects to the tub so that air pressure can pass through it to the pressure switch as the water level changes. The wiring from the pressure switch to the main control in the right front corner at the top.
It will work to fill if the pressure circuit is all that is faulty, but will error that LF you are seeing. Yes, I know how to run the diagnostics, but it won't be helpful. I can get you the instructions, though, if you would like.
