I ordered an Upper arm spray assembly from you. I am very mechanical but I am having a hard time figuring out how to replace it. Could you give me some instructions or tell me where I might find them online.
If you are talking about the middle spray arm (#618 on the break down diagram) - it is mounted to the upper dish rack.
If you are talking about the 3rd level spray arm (#570 on the break down diagram), then I’m afraid you have to remove the dishwasher from the cabinet at least half way.
