Out of balance

Replace all four struts

Here are a few quick facts on washing machine vibration.

1. All washing machines and dryer vibrate. Dryers usually have less vibration than washers because the load is only wet clothes (as opposed to a drum of water and clothes). Front loading washing machines cause high frequency vertical oscillation while top loading washers usually have horizontal oscillation.
2. Almost all front loading washing machines are not recommended for use on standard joist-construction floors (most common floor type, compared to a concrete slab sub-floor). Manufactures like GE, LG, Maytag, Samsung, Whirlpool, Kenmore, Bosch and more, all recommend installing a pad like Silent Feet under the washing machine to absorb the vibration.
3. The only alternative to using Silent Feet pads to prevent structural damage is costly upgrading of the sub-floor. This usually involves adding a second layer of plywood sub-floor and adding sister boards to the rafters that support the floor. But even this won't reduce the amount of vibration noise that you hear. Sub-floor upgrades can cost thousands of dollars.
4. Vibration can also cause appliance "walking" (unwanted movement) usually during the spin cycle. Simply installing a pad designed to prevent walking can solve this problem and mean that you'll never have to reposition your washer after every load again. Both Original Silent Feet and Anti-Walk Silent Feet prevent walking, however for washers that move a lot or stacked units it is recommended that you install Anti-Walk Silent Feet for the best results.

You were not specific in either type or model. I hope the above information helps. Also, the size of the loads plays a great part in how a machine functions. have a nice day
You wer

from the way you describe the issue it sounds normal, all washers vibrate at least a little or alot (depending on the balance or unbalance of the load) if it is just vibrating and not making a grinding or scraping noise it is fine, if its vibrating too much for your like, try to rebalance your load.

you may need to put some anti vibration shock pads under the legs or some two sided tape to put on the feet to help secure it to the floor it may be slipping on the new floor surface

the machine is not level... put a level across front back sides to check adjust legs leveling bolts as needed.... also is the machine installed on a carpet floor??? if yes put a sheet of plywood under machine so it wont "bounce" on floor.

The shock absorbers that hold the tank are broken. Then the load will move the washer all over the place.
Look online for an exploded diagram and order the new shocks for it

This is usually due to the floor not being perfectly level, and as a consequence the washing machine not standing firmly on all 4 supports.
There should be at least 2 adjustable feet under the machine, try to make it stand as level as possible, with uniform load on all four.
If you have a bubble level it may help you establish, if there's an obvious slope on your floor and adjust the machine so that it's well levelled.
Good luck!

level the machine, if you are on a wood floor it could be the floors fault, you could try using aanti vibration pads.

there may be a possibility here of the centre hub being worn or the liner tub bearing being worn due to the age of the machine.. here is a list and diagrams of the parts you may need and can get from here:-

try to check for slackness when the tub is empty causing a rocking/slapping motion whilst empty. if the tub is used regularly and to its maximum capacity then the likeliehood is these bearings/hubs may need to be replaced.. the "walking" across the floor will be accented by the amount of items plus water in the tub. and if the tub is off balance,then this will be more highlighted when also full of water and items... if you feel this is over the top,then try to lighten the load that is in the tub at any given time. this will determine weather the bearing has indeed worn .the lighter the load,the less "walking the machine should do in cycle.. the only time walking would be unchanged is during the spin cycle,when the speed is of a constant one and it will vibrate at the same rate. placing it on a rubber mat is not a solution but just something that will make you hopefully think it is solved
and you may as well just bolt the machine to the floor and hope for the best

I have the manual here please post your email and i will send it to you... The balance ring may have lost it water so yes it may need replaced.
