DWHD64CP ((38)) Thermador Dishwasher - Instructions

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.
3. unplug the wiring harness to the detergent/rinse aid dispenser
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.

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 slightly confusing as wires hook on a little different on new pumps. I suggest watching video the whole way through and then playing it step by step as you do the repair. Worked great for me. Thanks.

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 .

The old Tine holders used on the upper and lower dish rack dried up and cracked/broke. So I purchased new Tine holders for the upper and lower racks and snapped the new parts in place.

Went to on line video and followed it. The old gasket came right out and the new one fit right in. Started at the top middle and worked the gasket in on both sides to make sure it was evenly spaced.

To perform the repair, the door panel must be removed (8 Torx screws) and the door removed from the hinges in order to access the lower door seal. For this model Bosch and other similar models, the hinge springs must then be disengaged (safer) or kept from retracting. To disengage the springs requires removing the entire unit, disconnecting the water supply, and flipping it on its side to disengage the springs. I chose the latter, keeping the unit in place, holding the hinges with vice-grips on either side, then removing the door. This was not easy and caution is required. Either method is risky with a 20-year dishwasher.
The replacement part does not fit as well as the original (much sturdier) part, but appears to seal well for now. Repair videos on the internet are for different, newer models where disabling the hinges as described here is not required, making the repair much easier. Recommend looking carefully at your model/manual to determine if the difficulty of the repair is easy or hard.

Turn off power to unit!
-Remove kick panel,2 screws.
-remove water valve, 2 screws, 3 electrical connections, 1 hose clamp.
-Remove elbow from old valve and install on the new valve ( use teflon pipe tape)
-replace valve, hose & hose clamp, electrical connectors and water supply line.
Scew unit in place ,2 screws.
Check for leaks then replace kick panel, 2 screws.

There are two ways to do this repair: the "right" way and the hard way. I chose the hard way, as the right way involves disconnecting the dishwasher plumbing, removing the dishwasher from under the counter, taking all the outer panels off, and disabling the door springs. There are good YouTube videos on this. The hard way doesn't involve that -- but is not all that easy and I'm not sure I'd recommend it. The problem, in essence, is that to install the new seal there is now way to do it without taking the door off the machine and taking the door apart -- which requires that the springs be locked out, if not disabled.

I accomplished that part of it by opening the door, partially, undoing the two screws on each side which hold the hinges, taking the front panel off (piece of cake, with a Torx driver),slipping the door partly off the hinges, and then locking the hinges open with the pry bars.

There are an assortment of ways one could seriously damage either the door or one's self doing it that way -- the hinge springs are very powerful -- so I don't recommend my approach.

Vice grip door hinges. No need to disconnect, un hook hing springs. Works slick. Small vice grips. On hinges. Remove tore screws. Remove seal , and replace seal, reconnect door screws. Boom done.

Ordered the complete soap /rinse additive unit.nturn power off. Take the peripherical screws to remove the front of the door. Slide the door down and off. Unplug wires 2 places. Use a screwdrive to pry the tabs allowing the unit to come out

Important. Add a little Vaseline to the seal on the new part. Press it in until the tabs engage. Reconnect wiring and replace door front. Turn power on Job complete.

Dishwasher racks are maddening. It takes years to understand how to make your dishes fit within your dishwasher. We just moved and nothing was working so I did something that I did not want to do--pay attention to the lower rack and figure out why it had a mind of its own. Well, the Bosch interior is filled with adjustable (that usually means problems) fingers. Well, it was not so. A piece was missing that supported the "hand" from which the fingers sprang. That support piece cost about a buck and was available and ultimately on my doorstep in a day or three. Take the part out of the bag, snap it on the hand and enjoy dish racks that don't flop around. Awesome indeed.

REMOVED DISHWASHER FROM CABINET. DETACHED BASE FROM BODY OF THE DISHWASHER. INSTALLED NEW CORD, REATTACHED BASE TO BODY OF DISHWASHER AND REINSTALLED IN CABINET. OPINION: THIS IS A LENGTHY REPAIR AND UNNECESSARY ONE. THE CORD IS PART OF THE DOOR COUNTERWEIGHT AND SUBJECT TO TENSION EVERY TIME THE DOOR IS OPENED, AS WELL AS POTENTIAL CHAFFING DUE TO PROXIMITY TO VARIOUS METAL PARTS, AND VIBRATION. THE CORD SHOULD BE MADE OF STRONGER MATERIAL AND ARMORED OR ALLOWED MORE CLEARANCE. BOSCH SHOULD FIX TO LAST THE LIFE OF THE DISHWASHER.

My husband spent minimal time and maybe just screwdriver for repair of replacement part.
Your company was great to work with.
Thank you!

To replace the part per se was simple. To put everything back in place was more difficult as I took the base of the dishwasher off and a lor of other parts in order to reach for the drain pump. The irony was, after I took appart the base I fount a clip on the internet showing how to do that job and that was a very simple thing, couple of screws to take off the toe plate and the interior liner of the door, to create good access to the drain pump. Really a job of 10 minutes at the max.
