It turns out that the smells and other problems in new-style washing machines are caused by slimy bacteria, mold, mildew and other fungus growing on the plumbing and drum inside the machine. Bits and pieces of these nasties get transfered to the laundry during the wash cycles.
Hydrogen sulfide gas produces an offensive rotten egg or sulfur water odor and taste in the water. In some cases, the odor may be noticeable only when the water is initially turned on or when hot water is run. Heat forces the gas into the air which may cause the odor to be especially offensive in a shower. Occasionally, a hot water heater is a source of hydrogen sulfide odor. The magnesium corrosion control rod present in many hot water heaters can chemically reduce naturally occurring sulfates to hydrogen sulfide.
