Dishwasher Repair- Replacing the Upper and Lower Spray Arm Seal (Whirlpool Part # 3376846)

Hi, it’s Steve from PartSelect. Today we’re
going to show you how to change either the upper or lower spray arm seal in your dishwasher.
Really easy jobs; the upper one, all we’re going to need is a Phillips screw driver and
a small flat blade screw driver. For the bottom one no tools required; let me show you how
it’s done. To replace the lower spray arm seal first
we’ll need to remove the lower dish rack, set that aside. Remove the nut that secures
the lower spray arm to the pump, remove the spray arm and cover, and your seal is located
beneath that. Discard that piece, set our new one down over
top, reinstall the spray arm, and the retaining nut. Slide the lower rack back in to place. Remove the upper dish rack so that we can
get it on a flat surface where we can work on it, to do that we need to remove two rack
stops; take a flat blade screw driver, just depress the tab and lift up on them. Do the
same for both sides. Now we can safely slide the upper rack forward, off the tracks, push
the two tracks back inside, and we can set the rack on top of the dishwasher to do our
repair. Now that we have the upper rack inverted on
a stable surface where we can work on it, we next need to remove a single Phillips screw
that holds the supply tube to the mount. Lift the supply tube off, set it aside, and our
seal is located right there on the bottom of the upper spray arm. Insert the new one into place, line up the
supply tube, make sure it sits flush on that mount, reinsert the one screw, and don’t
over tighten it. Now we’re ready to reassemble. Now all that’s left to do is to reinstall
the rack. Pull our tracks forward; locate the rear wheels into the tracks, and the front
ones, ready to reinstall the rack stops. Make sure the bendable tab is on the top, stick
the bottom one in first, press it into place until it locks. And our repair is complete. I told you that was going to be a really easy
job; thanks for watching, and good luck with your repair.

    Thanks, Steve. I couldn’t figure out how to get the top rack slider stops out. Unfortunately, I reassembled and forgot to put the seal back in. What a dope! Got it all working fine now. Thanks for posting this. It was a big help.

    Hello Steve, I have a kitchenaid dishwasher wich is only 4 years old, the problem is that the top and middle (middle top spray arm only) won't spray water, when I put a wash the bottom rack dishes will came out clean but not the top rack, the bottom part is working fine. My question to you is what i should replace? I removed both spray arms and cleaned.
    thank you,

    How do you know if it needs to be replaced? The one you took out and the one you put back in look the same to me.
