Pappajon,
Have you removed the cabinet and checked to see if you have a leak from the tub seal or drain hose connections ? Based on your post, it's not overfilling, but you may want to check the air dome hose.
The jerky stop is usually due to an issue in the brake pads on the drive tube assembly, but they could have gotten wet, if the machine overflowed from the tub.
Here's some help for accessing the tubs and internal components.

1. Remove
the two Phillips-head screws securing the front corners of the console to the washer top. the two screws could also be located on the back side of the end caps.
2. Tip the console back on the hinges that secure the top of the console to the washer back.
Components inside the washer cabinet can be accessed by completely removing the outer cabinet as one unit.
1. Remove the console mounting screws and tilt the console into the service position.
2. Unplug the lid switch harness connector from the receptacle in the washer top.
3. Remove the cabinet mounting clips by placing the flat blade of a screwdriver in the clip and press down and towards the front to release the clip.
4. Remove the cabinet by tilting it forward and pulling it away from the washer.
5. The rear panel can be tilted back for additional access to components at rear.
Once you have the cabinet removed, you'll be able to visually inspect the hoses, tubs and associated parts. If necessary. you can bypass the lid switch and operate the washer, but be careful.

Good Luck,
