F2 means "motor not sensed to be rotating" The two go hand-in-hand in most cases. If you leave the drawer sit unused for months and months, this can ruin the motor rotor. The rotor comes out with no tools. Remove the dishrack, the wash arm (both simply lift off) and then the stainless steel filer/cover. This is removed by rotating the collar counter-clockwise and lifting it up. Now rotate the collar for the rotor counter-clockwise and lift the motor rotor out of the pump base. See if it spins freely. it;s probably frozen. You also can try swapping the rotor from the upper drawer into the bottom and see if that will work for you. if the rotor is bad
