We have a Kenmore Ultrawash QuietGuard 4 that does not fill with water. It\\\'s about a year, possibly year and a half, old. It drains fine, and everything else works fine, it just doesn\\\'t get any water. It makes a sound like it would be trying to pull water, and yet it just ends up heating the dishes until I close it and have to deal with the smell of every meal of the past few days being reheated... Any ideas?
