I had this issue with my W?D since the day I got it. I took apart all the reel stepper motors, cleaned them as others suggested.
I socketed the LM339's . No good. Ended up selling it a year later.

I noticed that if I left just one reel stepper connected the fuse took a super long time to go nuclear. All three connected, it got HOT fast!

So on a good day, I might get 50-60 minutes of play time before F116 blew.
So I just didn't leave game on unless I was playing it and turned off afterwards.

This circuit wasn't the best design but maybe that's all there was back then for technology?
