I have an upright washer that is relatively new (just over 1 year). Lately, after doing a load of wash, if I don't run another, the washer begins to stink. I make sure that I run HOT water often. I have to open the front panel and open the front drain to let water out. In a ice cream bucket, I probably get 1-2 inches of very gross smelling water. Is there something with the pump or could it be as easy as something as the discard hose too far or too shallow?
