Samsung wf337 Machine shakes violently as spin cycle increases

SOURCE: Bad shacking during the spin cycle

Remove top of machine and check the centralising springs are still attatched. If springs ok tilt machine against the wall after unplugging from the wall socket and check the shock absorbers. One of them could have jumped out of the guides. If shockies are ok, check the spider for cracks/breaks. The spider is the cast part that holds the outside drum in place. To check this you will have to remove the back plate.

I have a Kenmore 22990 top loading washer. it shakes violently and walks across the floor during the spin cycle. it started doing it about two weeks ago. moving clothes around inside the tub does not help much.

There is the tub that spins on the bearing the " the active tub"(the one the clothes go in obviously) and around that tub is the "stationary tub", between the two are what they call "snubs" these are either rubber wheels, bushings or on cheaper models just a rubber boot that works as a shock absorber if you will, and keeps the movement of the the "active tub" with in its axis. If a wheel is broken, or a bushing/boot is torn or broken then there lies your problem.

I hope this helps.

This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.

First, see the Sears parts site for your washer:
http://www.searspartsdirect.com/partsdirect/index.action

Enter your model number (###.######) and you'll see a list of major sub-components with diagrams and parts.

Whirlpool / Kenmore top load, direct drive washers use a number of springs between the main suspension plate and base assembly as well as friction pads that are designed to minimize shaking.

See the Whirlpool / Kenmore service manual for top load washers.

It's likely that one of the springs or pads has broken or come off.

See the following for how to remove the cabinet to get at these.

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.
