Wood, cement floor? Levelled how? Keep this washer as close to the floor as possible, get the legs out too far and it will wobble. Worn/broken suspension springs are rare, but the damper pads between the base and tubs can wear and allow the baskets/tubs to move around too much. Does the off-balance switch work? Draining drains out a full tub in approx 90 seconds?
The washer is located on a wood floor in an old house on the second floor. That not real level. I used a 2 foot level across the top to set it up. I will try and lower the feet, I know there are some adjustment there to gocloser to the floor. The washer has never stoped working, I was not aware of switch.
