Upper Spray Arm Mount

This gets a little lengthy... but it explains where Cascade Dishwashing Powder came up with its brand name - it's been a cascade project.
I started by replacing the Middle Wash Arm Tube as the old tube developed leaks. As others have stated this is a new design but directly replaceable and easy to do.
This didn't solve the cleaning issue so reading the experiences of others on this site realized I also had broken parts in the Upper Spray Arm Assembly and the Upper Wash assembly. I replaced these and the dishes were suddenly much, much cleaner. These were very easily replaced.
I did find that I did not need the Mount for the upper spray arm (PS402277) as a redesign of the Upper Spray Arm Mounting bracket no longer required it - the bracket simply clipped in -the diagram was out of date.
Everything seemed to go well for about 3 loads when the dishwasher started leaking heavily out of the bottom of the door. I then noticed that the lower Wash Arm Bearing Ring and the Seal, Lower Spray Arm had disintegrated so I replaced those but this didn't affect the leaking. Someone had stated that if the lower wash arm assembly had too much 'wobble' that it cause 'waves' that would leak out the front door... mine had some wobble so I added a nylon washer from Ace Hardware that reduced wobble but still leaked.
I then replaced the Door Seal Kit - this was by far the most difficult part as the door needed to be removed and it was somewhat difficult - and it seemed apparent after we had removed the door that these parts weren't the problem but we replaced them anyway.
Also, someone else had noted that they had to attach the door seal (this is NOT the gasket that goes around the door opening) with a sealant - I had the same problem; the original seal fit tightly with friction but the new replacement required an adhesive - I used silicone. Still leaked.
From here on I can't guaratee any useful information: I took the strainer screen out of the bottom of the dishwasher and found one slightly loose screw holding what I believe is the 'pump outlet' according to the diagram. I had also read that the water fill is controlled not by the float at the bottom of the washer but by the electronics and it was suggested that I disconnect the DW from the power to 'reset' the timer, this I did and hit the 'Cancel' cycle a couple of times to make sure that all programs were cancelled. Whether any of this made a difference I have no idea - except that the dishwasher suddenly stopped leaking and hasn't leaked a drop for at least 20 washes. So I don't know, for sure, why it leaked or how I fixed it, but it's working and washing great now - except the tines on the lower rack are beginning to rust out and breaking off. The rack is pretty expensive but so far I've saved a lot of money and my family thinks I'm a dishwasher genius.

First of all, we were very impressed with the ease of finding the parts, the ordering, and the velocity in which the parts were shipped. We received them the next day. I had to remove one of the screws from the old kit, since the new one only came with one. I looked at the diagram on the website of the assembly, and also remembered what the assembly looked like before I took it apart. The first time I tried it, I could not get the spray arm to spin without hitting the dishwasher rack. Since I had ran out of time, I had to wait until the next day. Once I started, I realized that I had the mounting bracket on backwards. Once I turned it around, I tightened the screws, and it was done within 5 minutes.

Removed upper basket and installed the arm. New snap in didn't require phillips screwdriver as old one and new support had split to insert. Replacing upper spray spinner dropped screw down around pump. This caused misery unassembling lower covers to receive Stainless
Steel, so magnet won't help ended up with mirror and hemistat to reach through large screen figures. So make sure to put towel or something in the bottom to catch parts.

we removed the cracked pieces and attached the new spray arm. it took some time because the new arm looked different than the old,but we did it.... I was the one to order the parts needed i had never done this before my husband said it was broken and we needed to buy a new dishwasher ( he was less than thrilled about that) so i decided to do this myself and find the parts. my husband was very surprised that i did it.... AND SO WAS I... IF I CAN DO IT YOU CAN DO IT!

The parts I ordered came in right on time and were easily replaced. Thanks.

I screwed the rack mount to the spindle using
the extra screw I ordered. I removed the upper dishrack's front stops and slid the rack
out. I clamped the mount to the dishrack. I screwed the rotor to the spindle with the screw that came with the rotor kit. I slipped the feed tube mount over the end of the tube and clamped it on the dishrack. I replaced the rack in the slides and replaced the front stops.

I had a hard time driving the screws. The slots are crossed but do not seem to be standard Phillips. The screws were hard to drive into the holes in the hard plastic. Before I could drive the mount screw all the way, the slot was too stripped to use.

a mater of unscrewing the part attached to the upper drawer...........placing new pieces together and srewing them on...............schematic on your web site was perfect.......had pieces sent over night.........wonderful experience

repair was ez I have no idea how old the machine is.

First, I compared the parts visually. The mount is a slightly different design. I removed the old mount/spray arm and tube by removing the single screw through the upper mount and un-clipping the rear tube mount. Next I assembled the new parts using the old spray arm as a guide. Note: Installing the new screw for the spray arm into the new mount proved very difficult and I needed to enlarge the pilot hole slightly in order to assemble. I proceeded to attach the new mount to the upper rack and installing the rear tube mount. The new design of the mount eliminated the need for the upper mount and even if I wanted to install it, it will not fit the new design. Overall, an easy repair with a couple of hiccups.

I pulled the top tray out by unhooking the end clips. Replacing the broken clips that hold the swivel racks was a breeze The top spray arm was replaced with two screws.
