JDB4950AWP Jenn-Air Dishwasher - Instructions

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.

Figured out that the only thing that could be causing this was a bad inlet valve. Repair was really easy. Didn't even have to pull machine out from under cabinet. First removed kick plate. Then placed towel under the old valve. Undid the power connections and water lines (in and out). removed the to screws holding the valve to the body of the washer. With the valve free, removed the brass elbow and installed it on the new valve. Reinstalled the valve and all connections. Works like a charm.

Took the replacment rack out of the box and found that it was the proper one. Had to rotate out the water director tower from the orignal rack and install it in new rack which took a few seconds to figure out . it was time to discard the ailing rack! Apparently the dish soap can attack the rack materia if there is any metal exposed and rot it out like rust so when this happens time for a new one. Otherwise there are no pins to support the bowls and plates in the lower section.

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.

I first removed the washer arm. Be careful because it is screwed on with the large center plastic piece with right hand thread. That allowed me to take the arm and disc off.

Next I took 6 screws loose with the allen wrench. This allowed me to get to the filter ring. I removed it and that allowed me to get to the three screws holding the discharge. I used a 5/16th socket to remove them.

A plastic disc that was part of the upper pump came loose and caused the noise. I replaced the upper discharge housing (with upper pump as part of it) and upper discharge housing gasket and reversed the order to reassemble.

The exploded diagram was a terrific help

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.

Remove the Palnut Screw from bottom of Float assembly using pliers, Remove Pivot pin from Actuator lever w/ screw driver. Replace the Float , install new palnut Screw and re-install pivot pin on actuator lever.

That's it !!!!!!!!!!!!!!!!

I did not move the dishwasher out. It is a fairly tight space underneath, but the water inlet valve is located toward the front, so it wasn't too bad. The steps were:

1) unplug the power and turn off the water to the dishwasher.
2) remove the 2 wire connectors.
3) use the nutdriver to remove the 2 screws that hold the valve to the side of the dishwasher.
4) use a wrench (5/8") to remove the nut where the water goes into the valve. This takes some patience since you can't turn the wrench very far in the tight space.
5) remove the water outlet hose by using pliers to squeeze together the clamp and move it up the hose. Then twist the valve to free the hose and remove it from the valve. The nibs on the clamp are small and take a little time to get them squeezed together. If the hose has been on there a long time, you will have to twist the valve a few times to free it up.
6) now you will have to remove the sleeve that the nut was screwed onto. I had to take the valve to my vise to hold it. Then it wasn't too hard to remove.
7) use teflon tape before you reassemble. Just go in the reverse order.
8) hope there isn't a leak. Mine didn't.

The new water inlet valve seems to have fixed the problem!

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.

Peeled off the old foam strip, cleaned with rubbing alcohol, let dry completely, applied new foam strip,replaced door interior done I wish repairing relationships with fiance and kids were one tenth this easy.

1. Print out the "pump and motor" exploded diagram and label the numbered parts down to #11 (discharge housing assembly).

2. Unscrew the "lower spray arm cap" (#34) by hand (it just twists off), remove the "jump up nozzle" (#1), and lift the "lower spray arm" (#2) and filter guard" (#36) out together.

3. With a torx screw driver, remove the screws holding the "pump cover and secondary filter assembly" (#4), taking note how the assembly was positioned. Be careful not to lose the two plastic "lower spray arm seals".

4. Lift out the "pump housing filter" (#6) and "rinse arm assembly" (#7).

5. With a 5/16 wrench, remove the bolts holding the "discharge housing assembly" (#11). You will likely find a plastic disk just sitting there under the discharge housing assembly. This is the source of your problem. It is the lower plate that has worn loose from the rest of the assembly and the noise is from it being ground by the impeller below.

6. The simplest fix is to order a new "discharge housing assembly" along with gaskets #37 - O-ring (for "pump cover in step #3. Mine was missing.) and #38 - "upper discharge housing gasket. Three parts to order and save your exploded diagram for when you put it back together.

7. Remove the "discharge housing nut" at the top of the old discharge assembly, lift off the "wash arm support", and put both on the new discharge assembly.

8. Insert new seals where they belong and reassemble the dishwasher in reverse order.

It takes about 5 min. to disassembled the lower jet system. As you disassemble, make sure you clean all the filters, and asses the integrity of the filters. If they are broken, you need to replace. Once you get to the impeller, you know it is broken because the lower part is loose. To replace you need to firmly hold the impeller as you unscrew the top screw. If the housing gasket is broken or too loose, replace. Otherwise you will have leak. Refer to your models diagram for proper assembly.

The repair is fairly simple except that the diagram on the web site has an error - it reverses the positions of the long hinge pin and the short pin. I kept trying to do it as the diagram showed and of course it didn't work. Then I followed my instincts! The only other difficult part was figuring out which way to insert the spring but there are only a few options so trial and error was the simplest way.

Since there are no nuts or anything else to remove on these racks, bending them into place is the only obvious way to go to fit them onto the existing racks. Taking out the old movable racks is the easy part - just take a pair of pliers and bend back the 'O' part of the movable rack where it goes over the pin on the big rack. To put on the replacement racks, I found that I had to bow the racks in the middle to make them fit. Simply pressuring them into place didn't have enough give. With a helper to hold the big rack steady, I could use 2 hand to bow and align the movable racks and snap them into place. You have to be careful not to bow to much or you could permanently bend the new parts. I broke one weld between the short pieces that go perpendicular to the long wires on the new rack by putting too much pressure on the long wires.

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
