When washing the dishes yesterday I opened the front door quickly to see if the top propellor under the top rack was shooting up water and spinning. I noticed the bottom propellor below the bottom rack was still slowly spinning and coming to a stop when the door was opened, but the top one had not moved. The setting for the wash was on normal wash, not pots and pans setting. Does anybody know if the setting matters regarding the top propellor spinning and shooting up water or is it supposed to always turn and shoot up water at all times? If it is supposed to always spin and shoot up water to the top rack, what would make it not work? Thx, Mark
