It sounds like the agitator gripping teeth are worn out. To check this, take the agitator cap off with a strong knife or flat-head screw driver, pull the cap off and check the plastice teeth and four plastic hooks that grab the teeth. If they are worn out, then you will have to replace the agitator. To replace it, you will see a nut that is between the circlular teeth. Unscrew the nut and pull the agitator up hard.

It sounds like you have a broken motor coupling. This is a very inexpensive and simple repair.

If the washer will fill and drain, but won't agitate or spin, you may have a broken motor coupling. The noise of the motor engaging, lack of agitation and ability to still drain are the usual symptoms. This is a common fail item with this model washer through normal wear and tear. Newer versions of the coupler are more resilient and resist breaking. The following link explains how to replace one:

The motor coupling is located between the drive motor and the transmission and takes the place of a drive belt. They do wear out and can break. The replacement part number is included in the link I provided and is an improved upgraded coupling that is more resilient. It should last longer. If you have questions, or require additional assistance, please let me know. I hope this helps you.

A replacement coupler can be purchased on line at appliancepartspros.com for about $11. Just use the part number in the link and "Search by Part Number" for your search criteria.

SOURCE: ultimate care supreme leaks underneath

First check the hoses to the machine. If they leak the water follows the hoses and drips on floor. Also check the hose connection at the washer. They will leak inside. Next it may well be a water pump going out or the plastic hose that is under pressure when operating. The pump is in the middle of machine underneth - Sorry - Good luck
