DU450 Dishwasher - Instructions

1) Remove the lower dish rack.
2) Use towel to soak up any water in the dishwasher.
3) Remove the bottom plate on the dishwasher front.
4) Remove clamp from around the discharge hose. Some water will drain out so have towel handy.
5) Dishwasher will need to be pulled out from its built-in area in order to feed the old discharge hose out and the new one in. MAKE SURE THAT THERE IS ENOUGH PLAY IN THE ELECTRICAL WIRES AND THE INPUT WATER LINE TO THE DISHWASHER TO ALLOW IT TO BE PULLED OUT.
6) Loosen, all the way, the white plastic locking arm that clamps the pump housing. It clamps on a white corrugated plastic piece.
7) Remove the spindle arm inside the washer by unscrewing the "tower" piece.
8) Remove the screws from the pump housing on the inside of the washer.
9) Lift the pump housing carefully and remove the rubber gasket from around the housing. There is enough play to remove the gasket and put the new one on.
10) Clean the area around the housing so that the new gasket seats properly.
11) The new gasket will have to be installed before re-installing the discharge hose.
12) Re-install screws in pump housing.
13) Re-install the spindle arm.
14) Tighten the white plastic locking arm underneath the washer that locks down the pump housing.
15) The new discharge hose can now be reconnected between the sink drain and the dishwasher.
16) Dishwasher can now be put back into its place.
17) Before closing up the bottom plate of the dishwasher, it should be run and checked for leaks before finally closing up. My advice - let it stand overnight before checking for leaks. after running.

Simply remove the washer nut,then pull the float assembly. As far the lever,just unscrew the screw and replace the actuator lever. What was great about everything I was able to go to the presented diagram. This allowed me to find the exact parts I needed. Of course make sure you have the model number.

Our dishwasher got to the point where it would not complete a wash cycle. I found that by jiggling the door latch, the dishwasher would whir back to life. For awhile, if I put a clothespin on the door latch, somehow enough pressure would be put on the switch to keep the dishwasher going. Finally, the dishwasher refused to cooperate...so I ordered a replacement switch.

The repair was easy. I only had to remove the interior door panel, unscrew the metal bar at the top of the door and underneath the door panel, then remove the black plastic shield. After that, it was just a matter of wiggling the old switch out and wiggling the new switch.

CAUTION: Be very sure that the power to the dishwasher is turned off. I got a scare because I thought the circuit breaker was off, but I had flipped the wrong one and suddenly, with my fingers very close to the bare connectors, the dishwasher came back to life briefly. I ran downstairs and found the correct circuit breaker and all was fine after that.

Take the bottom skirts off of front. Put drain solinoid back in its bore and secure with wire or a rubber band.It will be a chrome cylinder hanging Take the center spray section out and look for the broken lever. Get both pieces out if it split and fell in two. Mine usually crack and stay on the shaft. Pull the circlip off and slide new lever in place and replace circlip. Re-assemble center section. If you are going to keep the dishwasher buy extra levers. I buy them 2 at a time and try to keep a spare.

Removed old door gasket and water deflectors and replaced with new. Got the gasket in backwards at first. Removed and rotated 180 degrees and it went in properly. (Used tech video provided by parts select to help me.)

Though the old gasket was definitely bad, water still leaked after replacement.

Key issue ...... over time, contamination has accumulated in the water shutoff lever assembly and also on the shutoff microswitch underneath the internal water float, making both sticky and non-responsive to water level. Water had been overfilling. (probably defaulting to a maximum number of seconds to fill). ALSO - original installation was not totally level, with back of tub higher than the front.

Leveled tub. Removed mocroswitch and lever and cleaned both of sticky grease.

No more leakage.. basic problem was actually overfilling, allowing water to surge into the lower internal door vent upon pump startup.

Removed the old gasket. It was easy to "pop out" the parts that held the gasket in place with a regular flat blade screwdriver. Becareful not to chip the porclien (sp). Any of the tabs that broke off I just pushed them through and can take them out if I ever need to remove the front of the door. Works fine and no leaks. Clean the area of the old gasket so the new gasket will have a good seal. End of story.

cleaned lime and calcium build up off of gasket
and it stopped the leak . yea . parts select was very helpful and said i could return the unused
gasket. . this is a good place to get parts.thanks larry

Make sure dishwasher is powered off. Remove all inner door panel screws. Lift inner door panel upward and lean against the tub. Use a putty knife or spatula to lift old lower foam seal. Make sure door seal area is clean. Start at one end, butt new foam against the side of door and slowly pull glue strip backing while pressing foam down from left to right. Reverse door assembly.

Make sure dishwasher if off and door unlatched. Remove lower kick panel 4 screws and remove 1 screw securing float switch arm. Hold float stem with pliers and remove bottom stem nut. Remove float and re-install the new float with reverse procedure listed.
Super fast shipping on items!! Great service.

removed spray head, pulled motor/pump assembly. took apart impeller housing and then removed motor and pulled impeller off its shaft, the most difficult part was actually pulling off impeller from the splined shaft. I actually broke old impeller in the process. The good thing is that the new seal came assembled with new impeller so that was not a problem. After re-assembling everything it worked fine and still works for a week since repair.

Front Door Panel was replaced by unscrewing 3 screws on each left and right side of the dishwasher.

The bottom screws did not need to be completely unscrewed, just losen it enough to be able to remove the panel out.

Replace it with the new panel and screw back in the screws.

Actual i missed diagnosed the leak and ordered a very expensive door gasket. The leak was coming from shrinage of the wax resevoire o rig and the tab seal for the soap dispensor. I missed the trees the forest got in the way. The leak was dripping alond the front panel well away from the main door seal.

I cleans a the plastic surfaces and noticed a lip around the opening for the reservoire and used 150 sandpaper to remove it. Replaced the O ring, tab seal and bothe selonoids and cleaned everything. Put it back together. Works find lasts along time

All I had to do was take apart the door by removing a few screws. Then ripped the old gasket off. I then lined all the tabs up to make sure it was going to fit and then started pulling them through with needle nose pliers. When the door was reassembled I checked the plastic piece where the gasket ends in the tub and found some loose screws that needed to be tightened. After that I ran a few cycles and it does not leak any more.

The repair was EASY! Took bottom drawer out. Used tool to remove 3 screws that held belly screen and washer arms together. Used needlenose plyers to unscrew long pointed center screw (plastic!) then reassmenbled! Hey BATTA BING BATTA BOOM!

the spray arm is held in by a plastic bracket that snaps on or off over two points. I was able to remove the bracket without using any tools,just my fingertips. It is really simple!

I reviewed the choices available, found what I needed, ordered it, got it (quickly), and dropped it into the dishwasher....happy happy!
