Kitchenaid KUDS24SEAL5 Dishwasher spray arm wobbles.

[pjw73nh]

Greetings,  my KUDS24SEAL5 was not cleaning very well.  I noticed the lower spray arm was VERY wobbly.  It spins freely, but is VERY wobbly.  Yesterday, I replaced the washer arm bearing (WP9742946) which was worn paper thin. 

 

I also replaced the split ring bearing (WP3376846) on the bottom of the spray arm as well.  Though not part of this discussion, I replaced the split ring bearing on the upper washer arm as well.

 

I have only run one small load since, and it appears to clean better.  Too early to tell at this point.

 

One thing that bothers me is that even after replacement of the lower washer arm bearings, the spray arm was VERY still wobbly.  I didn't expect it to be.  The spray arm has what I would estimate to be 1/8" - 3/16" axial play if I pull directly up on the spray arm. 

 

How wobbly should this spray arm be?  Is there a clearance spec for it? Could the flange on the spray arm nut be worn so much to allow this wobble, or is the wobble normal? It doesn't look worn at all.

 

Thanks.

Think this is normal movement , cleaning out the filter at the chopper assembly will help most of the time. Should be able to find a u tube video on how to get to it.

Thank you for confirming this Eva,  While I had the arm off, I took it down to the motor assy.  Cleaned and inspected everything in between.  All looked good. The impeller nut was b1+ch to get off.  I had to use a 1" socket with vice-grips to hold the socket, and then put my nut-driver down in the drive hole of the socket.   To my knowledge it had never been removed.  Washer is about 16 years old. 

It appears, when I cleaned it all op, I loosened a bunch of black "gookus".... the first washer after the cleaning left a lot of black "gookus dots on the dishes.  One more wash took care of them. I suspect just jeft over debris I loosened up.

Thanks for the reply.
