Shaking stop SHAKES IN FINAL SPIN

The machine must be level or it will shake. There should be feet under the front which screw in and out. Get a spirit level and adjust the feet so it is sitting level front to rear and side to side.
Also make sure it isn't rocking slightly when it's not running - if so screw out one of the feet till it's steady. If you don't have a spirit (bubble) level compare how vertical the sides are to the wall/cupboards etc. However a level is best as even a little lean can make it shudder.
Or your putting too much washing in it!

Is the washer new? I had same problem it walked all over the room,then i found out it had some long shipping screws in the back that i had never removed,they needed to be taking out before first use, i believe it was 4 long maybe 5" long and each had a plastic spacer also meeds to be removed..good luck.

have you tightened the jamb nuts on the legs after leveling the machine so they can't move from where you set them initially when you leveled the unit?

It's usually a control board problem. sorry for the bad news :(

Most out of balance problems are from the clothes in it. Stop it, move the clothes around - kind of even out the load and try again.

Kenmore ECO Care system front load washer final spinal cycle
won't shut off. Machine shakes violently.

When the washer goes into spin cycle it is suppost to start at a slow speed and continue to increase speed (to a maximum of 800 RPM) as the water leaves the clothes. Your washer is going directly to 800 RPM which causes the washer to shake and stop giving you the E4 code. The control board that controls this speed increase must be replaced.

make sure the transport tie downs have been removed during installation and that all four feet are adjusted properly so machine does not rock.Also make sure your floor is reasonably solid.
