Very little water comes out of the top sprayer and the middle sprayer.Maybe just a dribble comes out of the bottom sprayer and the bottom sprayer does not turn.The dishwasher has water in the bottom I'm guessing that it uses to spray water out of the rotating arms.Does this sound like a pump problem?Model# 665 S#15989990 FJ 4304855 Stock# 15989 Thanks for any advice---CJ
