Whirlpool WTW4800XQ1 only agitates a few times during wash cycle

This question was asked a few years back about a Kenmore washer. I am copying that question here as it was very well explained:

“Why does my machine start agitating and then stop after a few strokes?

my machine started with this issue today, or at least i noticed it today. everything on the machine seems to be working fine, except the agitator. it will even agitate without any issue for a minute or two after I unplug and then plug in the machine, then it just stops agitating. there is no noise either, so it seems to be different than what generally causes issues with the agitator. for example, if the motor was spinning but the agitator not, it would make a noise, and the transfer of motion is what would be the issue. my case seems like the motor just stops period, or at least tha'ts how it seems since i cannot hear anything. the machine continues on as if everything is A-ok, will fill, go into wash cycle (but do nothing), rinse, and spin no problem. no blink codes or anything. any ideas?“

It is like the machine thinks it is washing but it actually only agitates a few times….maybe 10 times altogether. The rest of the wash cycle it just pauses, (there is absolutely no noise or movement) then goes to spin, rinse, etc., like normal.

As a side note, I just “inherited” this machine from my elderly mother who moved in with us. It replaced my slowly failing Kenmore machine. Also, I did run calibration mode, just in case, to no avail.
