With no clothing in the wash tub take the following steps:
1. remove the front cover from the wash tub
2. run a full cycle of laundry and observe the tub's behavior
A. If the tub begins to shake wildly during a full wash cycle with no clothing in it then you will need to adjust the 3 large springs on each side of the tub until the unit is working in a more-balanced position. This is simple to do by hand. If the tub appears to be shaking too far forward, then unhook the 2 large springs in back so they are tighter. Then run a full wash cycle again with no clothing.
* note: there are smaller springs too - you don't have to adjust these to fix your issue
B. If the tub works fine with no clothing during a full wash cycle, then try to load your clothing in a more balanced fashion. For example: if your wash load is only a small kitchen or bath rug then when the unit spins it will spin off balance with a wet & heavy item on only one side of the tub.
C. If you'd like to replace the 3 large springs, I can get you the part numbers. There are specific springs for both sides of the wash tub and they are different part numbers. The full replacement of the 3 large springs can be done by hand.
