Let's commit some purge - ery!
Andrew and Dadoes,
How about pulling the flow washers out and controlling the fill with the actual supply valve handle so you always get a full or nearly full tank of water? I know you are worried about your floor, Andrew, but the extra water in the purge will bring more hot water up to the machine and will give you an extra rinse before the final rinse and the same effect between the wash cycles too. You can get a decent amount in that way without having the water blast out like we did at my house! Besides, who else would operate it besides you and cause any damage?
