Dry drain trap
The hose from my washing machine emptys into the laundry tub. Is the sewer-like smell that sometimes comes from the tub drain due to a "dry trap"? How can I prevent this?

If you don't run a lot of laundry on a regular basis and don't run water in the laundry tub, then the trap can dry out, allowing the sewer gas into the laundry room.
Just run water in it on a regular basis.

A trap is probably not going to dry out in a week. It might be good if you tell us how frequently you do laundry.
You may have a plugged vent pipe that is syphoning the water out of the trap, and this can happen in minutes, not days.
Again, let us know how frequently you use the laundry, or better yet, run water in the trap, and smell it for the next couple of days.

If you do laundry a couple times a week, it sounds like a clogged vent (or no vent) on that drain line. The water in the trap won't evaporate that fast. It's being siphoned out. Look on the roof above the laundry tub. You should see a pipe coming through the roof there. You need to run a hose with a brass nozzle on it (water on full blast), or a snake, down that pipe to clear the obstruction.
