The whole wash was estimated 72 minutes when it started.
It weighs the clothes by inertia in the beginning, I didn’t overload, and the water comes in fast through thick pipes, so there’s no excuse for this.
How dumb must the program be to estimate one minute left in the beginning of the rinse cycle with two rinses and a spin cycle to go?
The building and presumably the machine were made 2018, and the maintenance log on the side says many repairs have been made since, so the software must have been updated many times already.
This happens once in a while with my washer as well. My determination is that it starts to spin and is so far out of balance that it has to refill and swirl the clothes around a bit, then drain it to hopefully get a more even balance of mass so that it can properly spin. It’s much worse when there are large items, like a blanket that tend to lump on one side.
