Kenmore washer model # 110.26422500 most of the time it spins but occasionly I have to turn the drum back and forth myself once or twice then it will start to spin again

SOURCE: Kenmore, model 110 26422500, type 111 Leaks when spin

The back panel does NOT come off on this model washer. In order to accurately determine the source of a leak on a Whirlpool manufactured TOP LOADER, you need to remove the exterior washer cabinet. This is procedure is much simpler than it sounds. The following link explains how:

In the majority of cases, leaks on top loaders are caused by a leaking drain pump, or drain hoses. Instructions are included to replace the pump if it found to be leaking.

Replacement parts (if required) can be found at the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The average cost varies, so shop and compare. The first three websites I listed also have helpful exploded view parts diagrams that can help you locate and properly identify the parts you need.

If you have any questions, please post back and let me know. I hope this helps you.
