Important
Before you wash anything in the dishwasher, check the materials chart shown in the table below.
Some materials are not dishwasher-safe and should be hand-washed. Others require special load-
ing considerations. Before washing any dishware or cookware, contact the manufacturer of the
material to confirm that it is dishwasher-safe.
Materials Chart
MATERIAL DISHWASHER USE COMMENTS AND/OR
SPECIAL INSTRUCTIONS
Crazing may occur.
Items joined by adhesives, whether plastic, wood,
bone,steel, copper or tin, etc. may be loosened.
Colored anodized aluminum may fade over time. Min-
erals in the water may cause spotting or darkening of
aluminum.This can usually be removed by scouring with a
soap filled steel wool pad.
Handles may separate.
Decorated china, stoneware, and crystal that is hand-
painted or trimmed may discolor,fade,or spot. You should
hand-wash these items. Position fragile glassware so that
it will not topple over or come in contact with other
dishes during the wash cycle. If you are not sure whether
a particular item is dishwasher safe,contact the dish manu-
facturer.
Milk glass may yellow.
Iron will rust.Wash by hand and dry immediately.
The Thermador dishwasher is only intended for use in
cleaning standard household dishware items.
After drying the non-stick coating should be covered with
a light coating of vegetable oil.
Pewter will tarnish.Wash by hand and dry immediately.
Wash only “dishwasher-safe”plastics. Decorated plas-
tics may fade.
Do not let stainless steel items contact copper, sterling
silver, silverplate, or dissimilar metal items.
Do not let sterling silver or silverplate items come in con-
tact with dissimilar metal items.

Loading the Dishwasher
•Use the Rinse Only cycle if waiting an extended
period of time before washing.
•Pre-soak and hand-scour pots and pans with
burned-on or blackened food.
•Do not place foreign objects, such as
toothpicks, paper products, plastic bags, or
packaging materials, into the dishwasher!
Pre-Load Preparation
•Remove large particles of food from the dishes
before food has a chance to dry but rinsing is not
necessary.
Food soils will actually
enhance the detergent’s
performance.
•Load dishwasher so water can circulate freely and
reach every part of item.
•Do not allow delicate items to touch; they could
be damaged.
•Place items upside down so water does not collect
inside of them.
•Place items so that nothing protrudes through the
bottom of the racks;
this could block the rotation
of the spray arms.
General LoadingTips
Before loading the dishwasher,
review the material chart pro-
vided on Page 5.
Place large and/or heavily soiled items in the bottom
rack of the dishwasher. Load heavily soiled pots and
pans face down, as shown in Figure 4.
For larger items,fold down the rear tines on the bot-
tom rack. When in the down position, they can hold
extra large utensils, such as serving spoons or large
knives.

and wait a few minutes for the indicator light to regis-
ter.
Rinse Agent Dispenser Regulator
The rinse agent reservoir of theThermador dishwasher
is provided with a regulator calibrated from 1 to 6.
(See Figure 15.) This regulator controls the amount
of rinse agent dispensed. The dishwasher leaves the
factory preset to 4. However,
NOTE: Refill rinse agent when the
level indicator shows a silver back-
ground with black lines.

Condensation Drying
The combination of a high final rinse temperature, the
tub’s cool stainless steel interior, and the sheeting ac-
tion of a Rinse Agent result in effective and efficient
drying. The closed condensation drying feature is hy-
gienic, and saves energy and money. For best drying
results,it is important that the RinseAid Dispenser be
kept full.
Unloading the Dishwasher
Unloading
When unloading the dishwasher always unload the
lower rack first and then unload the upper rack.This
will minimize the chance of water drops from the up-
per rack falling on the dishes in the lower rack. The
silverware basket(s) of theThermador dishwasher can
be removed for easy unloading.
Dishware tends to get hot immediately following a
completed cycle. If the door is opened slightly for a
few minutes before unloading,the dishes will cool more
quickly.
Figure 23
The Thermador Model DW44Z has an Upper Wash
cycle that saves energy and water when you have only
a small load of dishes. Also, you’ll use less detergent
for the UpperWash cycle. The washing time, however,
is not reduced.
The upper rack of the dishwasher has been designed
with flexibility in mind.You can load glasses,cups,plates,
bowls and small pots in many different positions to fit
your needs.Figure 24 shows a typical mixed load placed
correctly in the upper rack for the UpperWash cycle.

Accommodating ExtraTall Items
If you have extra tall items that cannot fit in the bot-
tom rack without interfering with the upper spray arm
or without hitting the top rack (max. height 22"), you
can remove the upper rack. A special accessory, the
Extra Tall Item Sprinkler, lets you run the dishwasher
with top rack removed. See Figures 27 and 28.
Installing ‘ExtraTall Item Sprinkler’
1. With top rack empty, remove it from the
dishwasher by pulling the rack toward you to the
point where you can lift it up and out, disengaging
the wheels from the side rails.
2. Place the “Extra Tall Item Sprinkler”over the top
rack spray outlet at the back of the dishwasher
tub and turn it clockwise to lock the sprinkler head
in place. See Figure 26.
3. Place the extra tall items in the bottom rack for
washing, as shown in Figure 25. To remove the
Extra Tall Item Sprinkler, turn it counterclockwise
and pull it out. Then replace the top rack.

two times, and again every 15 minutes until the dish-
washer is turned off.
To Enable or Disable the Cycle Completion Signal
1. Open the door,hold down the“Light Wash”button
and simultaneously turn the Dishwasher on. The
“Light Wash”light will blink (program mode).
2. While the light is still blinking,push the“Light
Wash”
button.
•If the machine beeps, then the Cycle
Completion Signal has been enabled.
•When you push the button again and it does
not beep, it means that the Cycle Completion
Signal has been disabled.
3. Turn the Dishwasher off to take it out of program
mode.

Use a soft cloth with a non-abrasive stainless steel
cleaner. For best results, apply stainless steel cleaner
directly to the cloth, then wipe the surface. Do not
use metal scouring pads to clean the stainless steel
surfaces as these can scratch the surface and leave
metal fragments that can rust.
Check Wash Arms
The wash arms should be checked periodically to en-
sure that the spray orifices are clear and unobstructed.
If the wash arms require cleaning they are easy to re-
move and replace:
1. The lower wash arm simply snaps into place. Pull
gently upwards to remove it.
2. The upper wash arm is held in position by a locking
nut. Turn the locking ring approximately 1/8-turn
clockwise to release the arm. See Figure 30.
3. After cleaning, reinstall the wash arms.
