Does the diverter plate look like it may be warped or damaged to cause the spray arm to sag that much? W11679656 Diverter (Directs Water To Upper Spray Arm) | Genuine Whirlpool OEM In Stock

Hi,

Def check the spray arm itself, could be worn, cracked and that is why the arm is wobbling and hitting the bottom.

Next would be the support for the spray arm. Could also be cracked, worn or broken.

#7 is the lower arm.

#16 is the diffuser.

#33 is the pump base.

Thanks for the reply. Doesn’t seem to be warped by looking at it but the spray arm does have some wobble to it

Spray arm itself does have some wobble

Would you be able to provide a picture of the lower spray arm and where it is hitting? A spray arm can have some wobble, but it should not be enough to hit anything.

Not too good at posting a pic on here but I gave it a try. Let me know if that worked. You can see the marks on the bottom where it has dragged and seems to stop in the same area when it’s finished washing.
