Fills fine. At start of wash agitation it does agitate, but it also has a loud click about once per second and the lights slightly dim at each click. At end of wash it drains, refilss and agitates at rinse with same clicking noise. Drains for spin cycle, but does not spin unless you stop the cycle and pull the knob back out. Then it clunks and spins. Any ideas what the problem is? Can a home handyman fix this one? Thanks, Dave S.

Have you tried it on different speeds?

Your symptom often occurs when the motor winding(s) are not engaging properly. In most cases I've heard of the solution was to replace the motor (see the following link) but can sometimes be caused by a loose connection in the terminal block of the wiring harness at the motor or if the motor speeds are controlled by the timer (as opposed to a separate speed selector switch), a problem in the timer can sometimes also cause it.

A problem in the motor itself is the most common cause of such symptoms in washers with 3 speed motors like used on your model. :(

If I change agitation speeds using the selector the actual agitation doesn't change. And what agitation it does right now is not normal. Changing spin speeds works fine.

I took the cabinet off tonight and watched the motor during agitation to see where the clicking was coming from. In time with the clicking I could see electrical arcing in the motor switch. I unplugged the machine, discharged the start capacitor and tested it. Good. I measured resistance for the motor windings - all normal. I put the wiring back together and watched again. Still clicking and arcing, but I noticed something unusual inside the motor. Something looked like it was spinning and stopping in sync with the clicking. I turned it off and looked again. There is what looks like a spring and weight assembly in that end of the motor. I couldn't get at it too well, so I got out my portable air compressor and blew out any dust, lint, dirt in there. Then I plugged it back in, started an agitation and it was perfectly normal. I ran the machine through a complete wash-rinse-spin and everything worked fine. What is that spring/weight assembly? How does it work? Am I just lucky that blowing it out made it work? Can that assembly be replaced by itself or would I have to replace the complete motor? Thanks, Dave S.

"What is that spring/weight assembly?"

That sound like the centrifical start switch.

Single phase motors (standard household power) have 2 windings, a run winding and a start winding.

The start winding works with the capacitor to "kick" the motor to help start it rotating and rotating in the right direction.

After they get up to speed the centrificl switch is suppose to open the start winding.

Air compressor "fix" is commonly used on older woodworking equipment, newer equipment uses enclosed motors to keep the dust out.

** What is that spring/weight assembly? **

As Bill said, part of the motor's centrifugal start switch operation.

** Am I just lucky that blowing it out made it work? **

I've never heard such a procedure permanently fixing a motor problem but you never know.

** Can that assembly be replaced by itself or would I have to replace the complete motor? **

Parts for motors (besides maybe the external switch) are not usually available separately. In fact most motors are now welded or epoxied together so they can't even be taken apart for service. If there is a problem in the motor, it usually needs to be replaced.

Given that this washer is not that old we will cross our fingers and see how long it goes before this happens again. Thanks for everyone's help! Dave S.
