DU599B Jenn-Air Dishwasher - Instructions

Remove old seal by pulling out tabs one at a time.

To install new seal, I had to remove the front control panel and door panel to access the back side of all of the slots that the new seal tabs go into. Using needlenose pliers i pulled each tab individually until they were locked into place.
Replace door and control panel.

With the dishwasher door open remove the 3 srews connecting the top of the dishwasher to the bottom of the kitchen counter top. Remove the lower access panel from the dishwasher and lower the dishwasher about 1/4 inch in the front and back of the dishwasher). Once you have lowered the dishwasher enough slide the dishwasher out about 6 inches (enough to gain access to the door springs on the left and right side). Remove all broken spring parts and replace using new springs. The left side of the door contained a single heavy duty spring and the right side of the door contained a heavy duty and light duty 'helper' spring. I replaced only the right side springs since the left side spring was in excellent condition. When the springs are installed slide the dishwasher back into its original position and raise the dishwasher back up to its original height using the front and back adjustment screws. Replace the 3 screws holding the top of the dishwasher secure to the bottom of the countertop. Ensure that the door opens, closes and latches smoothly and then replace the lower access panel. Job done.

This repair is very simple. Partselect.com sells a repair kit for this problem that you can use but for simplicity the entire unit is not that much more. First remove the four outside lower philips head screws on the inside of your dishwasher door. Support outer door panel while removing screws. This will remove the outer door panel to gain access to the detergent cup. Remove panel by pulling out bottom first then slightly pulling downward. You will then see the detergent cup. Unplug the two leads that are connected to the unit keeping in mind their orientation. Remove the five screws that hold the detergent cup in place. Remove the cup assembly and gasket. Clean gasket area and install new cup and gasket. Reinstall five screws (do not overtighten) and plug leads back in. To reinstall door panel position door panel at a slight angle and install top first sliding upward into place under control panel then push inward at bottom. Reinstall the four philips head screws on the inside and you are finished. The complete repair will take you less than 30 minutes.

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.

found detailed repair procedure at applianceaid.com which was relatively easy to follow - be aware that after years of service and some corrosion on the motor shaft it may be difficult or impossible to remove the plastic pump impeller and plastic drain impeller without damaging to get down to the shaft seal - the repair is not difficult for anyone with mechanical skills but I did have to order the two impellers and await their arrival before completing the repair.

Removed under-door front panel. Removed broken spring from right side. Hold door half open, insert spring with plastic bearing into hole in door hinge. Pull down to seat bearing in hinge. With needle nose pliers insert spring into hole at base of washer. ( You do not need to pull washer out of position)

remove lower access panel to expose spring. remove broken spring with longnose pliers. with door closed install upper hook of spring with nylon bushing on door hinge. using longnose pliers pull down on spring to hook on lower braket.

First, I removed the 4 screws & Toe plate assembly below the door, exposing the undercarriage. The springs for both the right and left side are visible. Secondly, to help gain access to the springs (and for ease in reattaching the new sping to the appropriate tension bracket), I opened the dishwasher door and unscrewed the two small screws (located above the door) that secure the counter-top attach brackets to the underside of the counter. This would normally allow you the opportunity to simply pull the diswasher out a few inches from the counter for easy access. In my case, the lip of the counter did not allow me to pull the diswasher out very far, but I was able to angle it just enough to make access easier. Thirdly, I referred to the diagram that accompanied my replacement spring to make sure that I had the spring positioned properly. There appeared to be a slight difference between tension bracket spring angle for attaching the spring to the door vs side bracket. Fourth, I attached the vinly piece provided to the top spring connection and simply pulled down on the spring to create enough tension to attach the spring to the lower side bracket. Finally, test the door to make sure you have the proper resistance. Push the diswasher back into it's original position, realigning the top bracket holes and reattach the screws that secure the counter top attach brackets. Put away your tools, pack your patience and you are done. It's easy!

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

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.

I would recommend getting the entire unit. I could have replaced the electrical component only, but the other parts were deteriorating.

I removed the 4 screws in the lower side of the door and removed the front.

I lossened the 6 screws holding the detergent cup. This was done with a small hex wrench.

I replaced the dispenser and connected the wires back onto the electrical sensor.

I put the front back on the door and tested the repair. Worked fine

I will be replacing the door gasket next. I found evidence of leakage when I removed the front of the door to replace the detergent cup.

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.

Easy to change. Just pull firmly on old gasket, clean surface with soapy water. Align tabs on new gasket, push into place a tap firmly with handle of a screwdriver and taps pop into place. Was done in about 40 minutes.

The repair was fairly simple. The hardest part was figuring out if this was the part I needed or not. After studying the inerds of the dishwasher door and the detergent cup mechanism, it seemed like this part would do the trick.

Here's how the mechanism works . . . the plastic stopper at the end of the bi-metallic strip latches the detergent cup in place. If these strips are bent away from the spring mechanism / plastic cam enough, the stopper will not latch on the cam (as was the case with mine). So, I needed to replace the bi-metallic strip. This part comes along with a new cam and spring.

The actual replacement of the parts is simple. The parts come with pretty good installation instructions.

Good luck . . .

Turned off the circuit breaker. Removed the two lower panels below the door. Removed the two racks from inside the tub. Removed the lower rinse arm, then unscrewed and removed in stages as much of the washer components from the inside bottom of the tub. Last item was the unit that screws into the base of the tub, was loose but would not come out, then I realized I needed to disconnect the water lines from underneath the tub. Then I was able to lift the pump/motor assembly out from inside the tub. Disassembled that until I reached the wash impeller, and saw that the shaft was no longer rectangular, but rounded out and spinning freely which was why the water was not being pumped out. Also found a small flip top from a can, no idea how that got down there, but that was what was making the loud scraping noise as the was impeller tried to spin. Reassembled everything and unit now works fine (and much quieter!) Never had to take the dishwasher out from under the cabinet and if I had to do this again it would only take 30 - 40 minutes - live and learn!
