Hot water hookup
You see, the repairman just left.
As it turns out, it was a pretty simple fix. One, it had to be "reset". He showed me how to do that.
Second, the installers *didn't hook up the hot water*. So, when I went to run the "hot water" cleaning cycle.... it freaked.
Poor washer. I feel bad for all the things I said about it, now.
The repairman looked at my "washer cleaner" products and said they are good, and I can also use a half cup of vinegar if I want, instead. I may alternate.
He was a very nice Indian man. He had a good sense of humor, too.
Of course I turned down my music, I don't - I take that back, I do know one person who would like my music, but most don't.
Anyway, it's fixed.
