Kenmore 70 Series Washer Banging - Delicate Spin Only

[ditobe]

Hello. Newbie here.
I have a Kenmore 70 Series washer that bangs during the first spin cycle while running a delicate load (i.e., the spin operation immediately following the wash cycle, and before the rinse cycle). The banging does not occur during the delicate final spin, nor does it occur at all during a regular (cotton/sturdy) load.
The tub is not out of balance. In fact, if I turn the dial from delicate first spin to regular first spin, the banging immediately goes away.
If I defeat the lid switch, I can see that the agitator spins clockwise, but with each bang, the agitator very briefly turns counterclockwise, then resumes it's clockwise spin.
Would greatly appreciate a diagnosis of what is wrong, and what needs to be repaired. Thank you so very much!

A video showing the characteristics of the problem probably would be helpful.

Does it recur as described when multiple delicate cycles are run in immediate succession, or a delicate cycle immediately following completion of a normal cycle?

Also, you didn't cite the model number ... is the machine a classic belt-drive (1986/earlier), a direct-drive (early 1980s to 2010) or perhaps a VMW (2010+, if any of those are labeled as a 70 series)?

Model number: 110.828702110
Serial number: C91816xxx

I acquired it used, so unfortunately I don't have a purchase date. I believe it's vintage late 80s or early 90s. Does the serial number provide the year of manufacture?

Yes, it does recur during multiple consecutive delicate cycles. I am pretty certain it does following a normal cycle, as well.

I will attempt to film and post a video. Not my forte, but I will see what I can do! Thank you!

I don't find a match for that model but it's apparently a direct-drive, serial references manufacture in April 1989.
