LF error code

I have a Maytag 2000 series that keeps showing LF error, Ive checked the hoses and there is no obstruction Ive also checked the filter screens and they are clear. When I open the top of the washer a part looked like it was hanging and banging against the drum. The part was a SWITCH-WI, it looks like it has an air hose hooked to it with a sensor. Perhaps to sense the level of water while filling up. The washer will fill for a while, the drum will turn a few times then it stops and registers the LF code. any suggestions please

Nobody got anything on this? What do you think out there? Water Level Pressure Switch?

Ok it was the water pressure switch, thanks all…great site!
