If the belt came off it could be a bad belt or a stuck pump.

The first thing I would do is remove the front panel. Remove two screws from each side of the front panel (on the bottom). Grab the front panel with both hands from the bottom and pull it up for about 45 degrees to release the clips on top of the panel.
Lift up the front of the washer and insert a 4x4 piece of wood under the front leg (or something else) so you can work under the washer. Unplug the power cord. Check if the pump pulley is moving freely. If it's moving hard then replace the pump. The part number for the new pump is AP243467

If the pump is fine then just replace the belt and it should solve the problem. I would recommend to replace both belts at the same time. If you buy them as a set you will save money. The part number for the pump belt only is AP247467 and the part number for the set of two belts is AP2660760.

The belts tension is self adjustable by the springs on the motor. When you'll put the belt on, just push the motor inward.

Good luck.
