This is not poor housekeeping. It's just a guest service annoyance.

COVID doesn't survive the washing and drying process. That's true for commercial equipment or what you call domestic equipment. (Although, every washer/dryer I've seen in a hotel is actually a step up from the "domestic" versions you'd find in most homes.)

Personally, if the equipment is being monopolized by the hotel, I'd give my dirty clothes to the manager so that the staff can put them in the washer (on their dime) when the machine is free. I'd expect them to call me when they do this so that I can move them to the dryer when the wash is done.

During "normal times", I'd be fairly upset if this happened. But, as bgasser notes, many hotels are struggling. They might not have $5,000 to $10,000 sitting around to replace their broken large commercial machine. So, right now, I'd give hotels a little leeway...especially if this is a small, limited-service hotel that might be owned by a single individual and not a massive REIT.
