KDTM704ESS Lower Spray Arm Hits Tub

Hello all - the pump filter on this unit "exploded" - a problem widely reported on this forum.

I replaced the entire pump and filter assembly. Now the washer is working fine, except that the lower spray arm is intermittently (not always) hanging up on the side of the tub.

I have to interrupt the cycle and re-set it. That seems to resolve things for a while.

Are there any educated guesses out there whether replacing the lower spray arm will solve my problem?

Or is it possible I inadvertently damaged the diverter housing, or installed the pump and filter assembly incorrectly?

I am fairly confident that I'm installing the spray arm correctly, but not 100 percent sure. I'm following the service manual directions, facing the corner arm to the front right corner of the tub, then turning the lower spray arm nut clockwise a 1/4 inch.

Thanks in advance - Chris

Hi Chris,

Are you sure its locked into place properly?

Here's the OEM lower spray arm assembly for your model:

FIXED - KDTM404ESS3 KitchenAid Dishwasher Spray Arms Do Not Rotate

I have a KitchenAid dishwasher that has worked as a champ but now has dirty dishes from the lower rack (top rack dishes are fine) starting earlier this week. I removed the lower spray arm, cleaned it (lots of gunk that had got into this) and put this back in the dishwasher. Unfortunately this...

Hi Jake, thanks for taking the time to reply. I'm fairly certain I've got it locked in, but can't be certain.

By the way, as others have indicated on this forum, your instructional video is not 100 percent correct. The Kitchenaid KD-17 technical manual indicates that the corner arm must be pointed to the front right corner of the tub when reinstalling.

The video should also make it clear that the lower spray arm nut needs to be grasped when installing or removing the lower wash arm.

Thanks Chris,

I didn't make the video, RepairClinic did, you can let them know that.

Just go by the KD-17 manual here: https://drive.google.com/file/d/1IABZRwoDnJElVXGVxsXNrdtXmyUJclAL/view?usp=sharing
