Hi thanks for the question.
Send me the make & model # XXXXX I will look at it.
Hi That d/w is made by Frigidaire.
What the problem is the wash impeller has broken from the motor shaft .
So the impeller cant keep up to the motor speed.But with that model you have to replace the complete motor and pump .And its not worth the repair.
Sorry I wish I had better news.
Sorry . There is a spray arm seal that seals the spray arm from the hose hooking up to the spray arm.If its worn the water wont all go to the arm.
