When in operation the machine itself is out of balance.

Call warranty service if brand new. Did you remove all shipping materials such as rods or bolts?

top loader or front loader is the data missing

Installation
Remove Wheel Balancer from shipping crate and pallet.
Place Wheel Balancer on flat and stable floor.
Install the Safety hood.
Install threaded rod to spin rod extruding from side of the machine
using the hex bolt.
If Wheel Balancer shakes or moves while spinning the wheel, it needs to be bolted to the ground to ensure proper function.
Electrical plug is preinstalled to fit North American 110 volt electrical socket.
Plug into proper electrical socket. Do not hard wire directly to your electrical source. There is no power surge protection on the machine. Please use a power surge protector to ensure your machine is not damaged.
Install the wheel balancer in a dry and safe environment. Exposure to moisture or extreme heat can damage the components inside the wheel balancer.

It could be the main shaft on the drum or misalignment. There is some flexibility, but not a lot. Check for worn belts, pulley wheels, and other attachments.

check lid isolation switch. check for balance of clothes. I would go for the lid switch first. The balance second as if it starts to spin and wobbles violently it will switch itself off to prevent damage and you will have to move the clothes around to balance the drum.

its called "Calcium-Chloride",its a type of salt water mixture put in these rings to dampen "OFF-Balance" loads in the washer,and the reason for this type of mixture is so people that store or operate the machine in below freezing temps do not have a solid off balance chunk of ice that wont balance the machine during operation or break the ring when it freezes

Usually, washing machine comes with fixing bolts in the back (for transport only). Check it out if were removed before operating. Usually, there are 3 or 4 of them, with some coloured plastic washers. In the instruction manual also is a note about them.

Most washers have a speed limiter in them to prevent the unit from damaging itself "IF" it is severely out of balance. Your solution is to redistribute the load, so it will not be out of balance and/or wash smaller loads so the machine can redistribute the load itself.

Hope this helps..
