Sorry, just posted question regarding slow agitate does not work, and I meant to write that I "manually" finish wash cycle by swtiching back and forth between pump and SPIN until I "guess" that the clothes are dry enough to empty and put in the dryer.

Thank you!

You cannot know until you troubleshoot it, but you are somewhat right. Here are some manuals to help you fix it: https://dl.dropbox.com/u/8010163/Und...c%20washer.pdf

I would not think that it is the clutch if it spins on other settings. There are electrical parts, like the spin solenoid, that could be bad, too, or other possibilities. Check it out with a good digital meter and you will know for sure what is causing the problem.
