There are a few things that can cause this issue.
1. The counter balance spring broke or the mounting hole for the spring rusted through.
2. One or more snubber pads may have come off.
3. The balance ring may have come loose from the basket or the ring has been damaged and the fluid has leaked out..
Start by removing the shell as follows:
A.) The trim on either side can be pried off from the top, grasp and pull forward to expose to expose a screw.
B.) With console lifted you will find a lid switch connector (white in color). Unplug the switch from the connector.
C.) There will be two brass colored clips. Place a flat blade screwdriver straight down into the opening on top of the washer and into the groove of the clip. Push the screwdriver down and away from you and the clip will release.
D.) Open the lid of the washer and place your hand under the front rim of the opening (DO NOT grab the wash tub). Tilt and slide cabinet forward to remove.
1.) The counter balance spring is located in the bottom rear. It should be attached between the cabinet and a bracket on the tub.
2.) Inspect snubber and corner pads. May be brown or white in color.
3. Remove tub ring by pushing down then lifting each locking tab.
Inspect balance ring for proper fit and any cracks. By moving/shaking ring you should hear liquid sloshing around.
