JDB1090AWS Jenn-Air Dishwasher - Instructions

I pulled out the dishwasher enough to tip it back and put a block of wood underneath the front leveling foot.
This step gave me more room to work on the valve.
I removed the lower cover plates to expose the valve.
I disconnected the incoming water line and unplugged the electrical connection.
I then unscrewed the bracket to release the valve from the case and took off the rubber hose attached to it.
I installed the rubber hose on the new unit and installed the bracket back in place. I then wrapped some Teflon tape on the threads of the valve fitting and re-installed the water supply line. I re-installed the electrical connection.
I then turned on the water to check for leaks. Once I was certain there were no leaks, I re-installed the lower cover plates and took out the wood block and pushed the dishwasher back into place and re-installed the screws that held it in place.
I then ran a load of dishes to make sure everything was working properly.

The actual problem was the plastic wash arm cap was worn down and not holding the spray arm in place allowing it to hit the lower dish rack and stopping it from turning. The cap is on a threaded steel stem and is easily removed. The spray arm lifts off the stem and its replacement slips right on. Then install the new wash arm cap by screwing it on the stem.

Lifted out old silverware basket. Set new basket in. Took approximately 20 seconds.

In order to clean the screen I had to remove the impeller. Removal required using a wheel puller. I backed off on the impeller screw but left it attached so that the wheel puller could pry against it. I then tightened the puller enough to free the impeller. I was then able to unscrew and remove the screen for cleaning.

Removed the old one....slid in the new one.

Turned off water at the shutoff valve. I did not turn off the power, but it is recommended you do so. I pulled the dishwasher out from under the cabinet and used a car jack to lift the front off of the ground. Disconnected the water supply and the rubber hose that fills the dishwasher tub. There are two 7mm screws that hold the water pump to the frame. If you do not have a 7mm socket, the easiest thing to use is an interchangeable screwdriver. When the screw bit is pulled out, the empty screwdriver is a 7mm. Used adjustable wrench to remove the brass water port for the supply line. Teflon tape to all connections and hooked everything back up. My supply line was old and was leaking, so I had to run out and get a new one, so that added about 30 minutes to what would have been maybe a 20 minute repair.

Remove the water distributor, filtration plastic parts down to the base of the tub and clean of debris. Sometimes a small piece of plastic from the upper glass tray can break off and find its way into the bottom. Once its cleaned this section and be put back. Had to remove the unit from the cabinet and replace the drain motor and also cleaned the drain hose that runs to the garbage disposal. Most times this problem is caused by a blocked drain line or debris in the bottom of the tub constricting waster water from getting into the drain motor.

I had to lightly pry off the long piece of plastic next to the wheel assembly because I had to twist the assembly counter clockwise to remove the old one. Also had to place the new one so that it rotated clockwise to seat it. Then replaced the other plastic piece.

1. Remove both upper and lower dish trays
2. Remove the “Spinner /Sprayer” (small nut on the top)
3. Unclip the “Tower” from the top and rear clip
4. Remove the “Tower” from the unit
5. Remove the “Filter Guard” on the bottom by removing 3 torx screws

7. Remove and replace the “Accumulator Filter” (8 – 20 torx screws)
8. Assemble in reverse order

I followed the instructions here on PartSelect to dismantle and put the new impeller in to place. Could tell the difference just in sound alone once it was running.

Followed the instructions to dismantle all the way down to the motor. Replaced the stripped plastic shaft with the metal one. Clean dishes every time.

Pulled dishwasher out far enough to get at the original hose. Disconnected and drained the hose. Connected new hose, zip tied the hose in place, pushed dishwasher back in place and re-anchored. Zippidy do...piece of cake. Perfect fit.
