Thank you for submitting a question to Manage My Life. I know how frustrating it can be when appliances do not function properly.
A problem with the rear tub bearing or the spin basket could be causing this problem. With the washer empty, check for forward/backward play in the stainless steel spin basket in relation to the plastic outer tub. Also check for upward play. Push up of the top front edge of the spin basket. Spin the basket a few degrees and check it again for upward play. Continue to check the basket around the whole 360 degrees. If you find a section where you detect significant upward play, then you likely have a bad spin basket and may also have a bad rear tub bearing. I also recommend removing the top panel and checking the springs. To remove the top,
unplug your washer
and take out the screws along the top rear edge, then slide the top back and lift it off.
This washer has a 10 year warranty on the plastic tub and lifetime warranty on the steel basket, so if your washer is less than 10 years old I recommend calling for service.
I highly recommend having a trained service technician evaluate this problem. You can have it repaired at your home by a Sears technician. Here is a link for the website:
