DWHD43CF (21) Thermador Dishwasher - Overview

With the help of You Tube, this 50 year old Mom got the job done. Not that complicated if you watch the step by step instructions on the Appliance Pro video. My repairman and husband were both determined to just buy a new one but this 20 year old dishwashing genius was just in need of a little repair. Only need a screwdriver, and sli ...

Thanks.

Here are the steps you need to take to do the job properly:

1. turn off electrical circuit breaker to the dishwasher
2. remove 8 total hex screws (3 on each side and 2 at the top) of the inside door panel. The door panel will slide off so be careful and it happens pretty quickly when the last hex screw is removed.

4. you need to use a flat head screw driver to lift the metal flanges on the top and bottom of the detergent/rinse aid dispenser.
5. the unit will pop out toward the inside of the dishwasher
6. insert the new detergent rinse/aid dispenser and very important all metal flanges are pulled back over the plastic edge (top and bottom) of the dispenser unit. The screw driver needs to be used to assist in pushing the dispenser unit as tight to the frame of the door to ensure the metal flanges grab hold and lock in.
7. re-attach the wiring harness
8. re-install the dishwasher door with 8 hex screws. Doing this step alone is challenging as the door frame will want to keep going up to close. I used a small foot stool and placed it inside the dishwasher front area on top of the inside metal door area so the door would stay open roughly half way. I then used my knees to prop up the outer door cover while i got 2 screws started then was able to easily complete the job.
9. run the dishwasher with a detergent packet loaded into your new dispenser. I checked for 15-20 minutes during initially running to insure no issues or leaks.
10. One last note - my Bosch dishwasher had a custom wood door installed to the outer panel to blend in with our kitchen cabinets. The door itself was much heavier as a result. Some of you may not experience the slight difficulty i noted above in step 8. Good luck.

I used a wet vac to remove the water from the dishwasher. remove cover and filter/strainer from bottom of dishwasher. remove screw which allows you to lift the plastic piece to access check valve. Original check valve looked like new , I installed new check valve re installed parts . Job done and issue resolved .
