DU450 Dishwasher - Instructions

I googled the simptoms online, and found that the most common cause for a door leak was the door seal. I purchased the seal online from PartSelect.com. Two days later, the part arrived. I pulled out the old seal and pushed in the new one. No tools required. That fixed the problem. While looking at the parts diagram, I noticed that my dishwasher didn't have the water deflectors installed. I don't know if they were ever there. They were cheap, so I ordered them online and slid them into place in less than 10 seconds. Again, no tools required. Dishwasher runs great, no leaks.

I removed the screws on the inside of the door. Removed the cover and changed door switch and holder and put the new one in. Replaced the cover
all in less than half an hour.

The real cause of the leak had nothing to do with the foam strip. The latch for the front loading door at the top needed to be adjusted to hold the door in tighter to the rubber door seal. This simple adjustment stopped the leak but since the foam seal was all encrusted with dried detergent from probably years of absorbing the leak, I replaced it with your new foam strip. I used a screw driver with torx bit and removed the stainless screws holding the inner door to the outer door. Once these were separated I removed the old foam strip using a putty knife and lacquer thinner. Placing the new strip onto these cleaned surfaces was the easiest part of the whole repair.

The dishwasher is well engineered to perform this work.

Remove the bottom two panels to provide access and visibility to base of pump motor.

Locate plastic pump locking lever and push toward rear of DW to unlock pump from DW.

Inside the DW remove basketsand spray arms. Revove screws holding cover over pump motor and remove cover.

From below raise pump motor and support with block (piece of 2x4 worked well).

insde DW, removre old gasket, clean well around pump and botom of DW, install new gasket.

From below remove block to drop pump motro back into place, and re-tighten locking lever by pull toward you.

re-assemble inside componets, run through a rinse cycle to test for leaks and replace bottom panels.

Removed the gasket by pulling it's tabs out of the metal slots in the door. This was accomplished by accessing the inside of the door.
Then I realized that I had to dissassemble the side and front panel of the door to install the new gasket. The reason is you have to pull the tabs through the metal slots in the door from the front side. I used needle nose pliers which worked well. Then I had to reassemble the front and sides of the door. No more leaks!! for now. Takes some time if you do it by yourself. Budget at least 2 hours.

Easy. Removed screws at top holding dishwasher to counter. Turned off water to dishwasher. Unhooked water supply line. Electrical and waste lines were long enough to leave connected and pull dishwasher out, set on side. Pull off electrical connector. Use pliars to compress spring holding water line to dishwasher, remove that line from valve. Use nut driver to remove old one, and replace with new one. Teflon tape on water connection to sink. Do everything in reverse.
done.

It just snaps back in but it was a very tight fit and took two people to force it in. Plus I had no instructions and hadn't seen it before it broke so it took a little time to figure out where it was supposed to go. The arm doesn't connected to anything except the rack. I guess water just shoots up into it from below.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

The dishrack came in one box I opened the box snapped on the rollers and the bumpers and put it in the dishwasher, could not have been easier Thank you partselect

I had already loosened the motor from inside the tub....so it was fairly easy to wrap the new belt around the motor/pulley system.... even though the old broken belt was 2 inches longer than the new belt(probably as a result of age and use, but the new belt is obviously the right size!) Once in place, I did have to take some care in screwing down the seal from inside being as it wanted to go more to one side than the other from the pressure of the tight belt, but all in all, it wasn't so bad. Unfortunately for me when I put the dishwasher on, I thought the dirty water problem would go away, but I soon learned that I also had a clog in the plumbing. I guess I'll never know if one thing caused the other or it was just 2 things going wrong at the same exact time. But everything is perfect now. Also, the part I ordered was at my doorstep in less than 36 hours!!!! That's fantastic!

Removed the existing dispenser door, took off old spring. Slid new springs on pin, got it situated between the correct parts of the door. Popped it back on the pin inserts. Twisted spring into springing action position, voila. It was repaired. No repairmen. No additional costs, fees, nor extra time waiting on repairmen.

had to remove the spray nozle and cover from the bottom of the washer to expose the stem where the lifter mounts. I had to turn the stem slightly to install it, this had to be done from the bottom of the washer and it took an extra set of hands. Once the stem was in the right position the lifter slid right on, I attached the retainer ring and put the othe parts back on. It works as good as new now.

The replacement of the spring linkage was simple - the pulling out and pushing in of the under-the-counter dishwasher was the difficult and time-consuming part. The repair of the part took less than a minute.

The actual repair -
1. Hook the linkage to the dishwasher door
2. Hook the spring to the dishwasher base
3. Hook the spring to the linkage.

Getting the dishwasher out to be able to make the repair involved:
1. Unscrewing the base panel (6 screws had to be removed)
2. Unscrewing the dishwasher from the counter (two screws)
3. Turning off the water supply
4. Disconnecting the inline water supply from the dishwasher.

Once the part was replaced, I had to return the dishwasher to its original position, which meant performing the four steps (in reverse) used to pull out the dishwasher.

Removed old gasket and foam strip. Cleaned area. Installed door gasket. Trimmed foam strip to fit and installed.

Leak has stopped!

After searching on the internet for a very long time, we were almost ready to order the screws "blind" (no picture) from Sears for almost $10.oo per screw. Then I stumbled onto this website and found exactly what I was looking for, with a detailed description AND a picture!! Not to mention a price that was two thirds less than Sears..for TWO screws. Now the oven door is secure and we are no longer on our search for the right screws.
