Is the hot water turned on. Remove hose from washer and check screen in water inlet. If it is clear you may need a new water inlet valve.

I will find my answer by testing the behavior myself. It would have been nice if you could have confirmed what I was asking. It is a complex machine, but all its behavior should be known by someone, and that is you.

you can goto sears.com and goto parts, put in your model # and they have a parts and diagram that you can look at.. sound like your basket block (which holds your basket on the gear shaft) is loose.. or 3 bolts on bottom of washer the holds gearbox to frame is loose.. good luck

This problem, or some variation thereof evidently is very common with these Whirlpool Washers!  I have same problem.  So far, best I have found is at  http://applianceguru.com/forum2/5958.html#
diagnosis by someone who knows.  What William Burk says there makes sense.  However, to get to the drive block there's quite a bit of disassembly required.  I am stopped because I cannot get the spanner nut off.  Hope this gives you some help toward finding a more comprehensive answer

there isnt, or at least shouldn't be a buzzer to let you know its changing cycles, only end of cycle. if its buzzing betwwen cylces theres problem a woudl assume eith timer( if theres a selector forit try turning of end of signal chime any way

pull up and down on your basket to see if it has up and down play in it
