the washer will not spin on a full load and only will on a very small load if you help the tub start spinning

The first thing I would check is the drive block. In order to do it you have to remove the cabinet and the agitator.

Remove the tub ring unsnapping the tub ring tabs from the tub one at a time.

Next step is to remove the spanner nut. You can do it using a hummer and a screwdriver or you can buy a special spanner wrench . However, it is recommended to use the special spanner wrench to properly tighten the spanner nut at the end of the repair.

Carefully remove the basket by lifting straight up. Using a hummer, carefully tap up from the bottom of the drive block to remove.

Inspect the notches on the drive block and the tabs on the spin tube. If the notches on the drive block are worn out, replace the drive block.

If the problem is worn out tabs on the spin tube there is more serious job because the spin tube is a part of the basket drive/brakes assembly and to replace it you have to remove the gear case (aka transmission). Let me know if you are going to do it and I'll help you.

Good luck.

If you find the spin basket is tight on the spin tube, then you probably have a failed clutch, just check.
