DU450 Dishwasher - Instructions

I opened the door and pulled the old gasket out using a flathead screwdriver to pry up the difficult to remove areas. I cleaned the area with a damp cloth and place the new gasket in the slots. The entire process including the cleaning took no more than 10 minutes. It was so easy. By the way, I had the part in my hands 2 days after ordering it. I am very impressed with the service.

The repair was very simple and covered completely in the instructions that came with the springs. However, I am writing this not so much to describe the repair but to give unsolicited praise to PartSelect. I pretty much only purchase online, so I spend a lot of time on web sites. This was probably the best shopping experience I have ever had (Google and Google Tool Bar were also involved). I found the site using Google, but then found my part in about one minute with the great diagrams. Checkout was incredibly easy and my parts arrived two days later and the door was fixed 30 minutes after that. I'm a customer for life!

First unplug the unit. Open door. Take a special tool to remove all the screws (star shaped) around the edge of the door, and remove plastic panel where motor for detergent cup sits. Remove wires (two) from the motor. Remove wax motor by unsnapping motor from its cradle--comes out by moving the fingers holding it in. Push new motor into position, being sure the round pin sticking out at the end (on the left side) so that it sits in the groove made for it. Replace panel and screws, plug power cable back into its box. Close detergent cup door, turm on dishwasher, run through cycle, open door and check to see if detergent door opened up. If it did, then fill with dishes and wash.

First, I searched the repair help on this site to see what others did to repair their diswashers, and it looked easy, so I just followed the same instructions. First, I used a hex star key wrench to remove the screws that hold in the interior door cover. I disconnected the leads to the defective wax motor, reconnected the leads to the new motor and screwed the door back together. It took 15-20 minutes and was a piece of cake! My first appliance repair, and as a single woman and first-time homeowner, I was really impressed with this site! It gave me confidence to tackle more home repairs instead of calling for service and getting raked over the coals.

Belt seemed too small at first to fit, but turning the power module pulley while holding the belt enabled it to slip in properly. Didn't help that there's not much space to work.

On my maytag portable dishwasher I had to remove three side screws on right lower panel,and two lower screws to free up panel. I had to pry the panel away from the body to get axes to the springs. Replaced springs as instructed reinstalled all hardware, finished.

This is the second time I have replaced a rack. You just pop on the new rollers and you're good to go!

I hand screwed the pieces together and screwed them by hand into the proper location in the dish washer. I turned on the dishwasher and it worked !!!!

My dishwasher hasn't been working for 6 years because of this broken part and I couldn't afford the house call of a tech. When I found your site I realized I could do it myself !

ALL HAIL PARTSELECT.COM!!!!!!!!

Thanks to your diagrams and easy to order parts I am a happy homemaker !!!!!

I used the parts blowup diagram on PartSelect.com and dissasembled the bottom wash assembly. Carefully examining how the washer arm rotated, I determined that the spray arm support nut had broken. The extended top of it has broken off. This nut, when tightened, allows the spray arm to rotate freely. In trying to diagnose the problem, I had even removed the motor assembly at the very bottom. When I reassembled it, I apparently did not seat the gasket well and did not tighten the bolts well, so when I tested the washer, water leaked out the bottom. So, I had to dissasemble it all again and properly torque the bolts. So, I really created another problem during the diagnosis.

Put spring in plastic bushing, snapped into door arm and hooked opposite end of spring in first hole. Repeated process on opposite side of door. Did the above without moving the dishwasher from installed position.

Once the covers under the door are removed, the check valve is visible (unless its too dark, hence the headlight), and pointing right at you. Since I was working under the dishwasher, I gathered all the tools I thought I might need and laid them on the floor next to. Removed 2 covers, placed pan under check valve and hose to catch any water, squeezed clamp with (wrong) pliers, it eventually came loose. Carefully twisted hose off check valve. Water came out, some of it got into the pan, most of it on the floor. I guess I should have pumped it out before I started this. Plastic check valve is screwed into the big piece of whatever, carefully grabbed it with (wrong again) pliers and turned it out. Installation is reverse of removal - but use a large pliers with a ROUNDED jaw to grab the round check valve body. Don't squeeze too hard or overtighten it. Put the clamp on the valve before pushing the hose on. Be sure the hose seats all the way onto the little lugs. Compress the clamp, slide it over the end of the hose and release. That's all folks, works good now.

The replacement part was the perfect size but the threading on the terminal ends was increases to 1/2" v the 7/16" from the previous element. My first attempt was to find a similar type of part at the local hardware store(not a superstore)since I planned to replace the grommets anyway. After not having any success, I came home and modified the fasteners by slowly drilling out the id of the fasteners until they threaded properly. The time to replace after the drill out was less than 10 min and the ~$45.00 is significantly less than $450.00 for a new unit.
If I would ask anything of part select, it would be to include fastening hardware as re-engineering of products is a continual process.

I layed the bottom rack upside down on the counter. Removed the old wheel sets and the new ones just snapped into position. I think the rack rolls better now than it ever did with the original equipment. I'm glad we purchase the Tandem Rack Rollers instead of a new dishwasher, it works great.

removed old check valve from bottom of dishwasher and replaced with new one. I used channel locks to do this, disconnect hoses and screw out check valve, and put back in opposite order, make sure the dishwasher is empty of water or have a plastic bowl or such to catch water. Take off two front covers on bottom of dishwasher to access check valve ,white with hose attached.

This was really easy. I just took out the two screws securing the unit to the counter top and slid it out about 6 inches. Broken plastic spring linkage was obvious and easily accessible. I didn't know there was one on each side, I would probably have went ahead and ordered both and replaced them at the same time.
