Product Overview
The Bosch dishwasher utilizes a two motor system with separate Circulation and Drain Motors, and a Flow Through Heater controlled by a Flow Switch and NTC Thermistor. With some models also having the advanced logic feature of an Aqua Sensor turbidity measuring devise, Fig. 2-1.
A two motor system allows each motor to be designed for a single function, thus reducing overall size and energy consumption. While also reducing operating noise.
The Flow-Through Heater allows a shorter heating cycle since all water must pass through the Heater, increasing water temperature by approximately two degrees a minute. To protect the heater from dry fire, the Flow Switch will not allow the Heater to activate unless water is flowing.
Water temperature is controlled by the NTC (negative temperature coefficient). As water temperature increases the NTC records the decrease in resistance. The Control Unit Logic Board measures this resistance change and allows the program to advance once the correct temperature (resistance level) is reached.
The Aqua Sensor turbidity measuring device, which is available only on select models, evaluates the pre-wash water using a beam of light and a pick-up sensor. If the beam passes easily through the pre-wash water then no additional wash water is added. If the beam cannot pass through, then the pre-wash water is drained and a fresh fill is added for the main wash cycle.
The heated water then advances through the system via a four level wash system that uses both an upper and lower spray arm as well as an overhead sprayer, Fig. 2-2.

The SHU 30** and 40** are both mechanical units that operate using a basic Timer and Selector Switch.
TO OPERATE EITHER MODEL, (a SHU 4006 is shown):
Fig. 3-2.
First select a cycle by pushing the corresponding Cycle Button in. The Cycle Button remains in the indented position until another cycle is chosen.
Now, depress the On/Off Button until it locks in place and the On LED illuminates.
Note: The On lamp will remain illuminated until the On/Off Button is depressed a second time
turning the unit off.
If the door is opened during the cycle, the On/Off Button will be reset to off and must again be depressed to re-active the unit.
Fig. 3-1.
Then, turn the Timer Knob slowly clockwise to the start position and release. You will hear the Drain Motor activate.
The Timer Knob will continue to advance clockwise back to the twelve Oclock position until the cycle is complete.
Please note: During the Rinse & Hold Cycle the Timer Knob will only advance to the two O’clock
position and then stop, indicating the end of the Rinse & Hold cycle.

Fig. 3-4.
Once the On/Off Button is depressed the LED above the previously used cycle will illuminate.
To change the cycle, simply press the desired Cycle Button twice. The LED above that cycle will then illuminate.
As the program advances the Cycle Progress LED’s will illuminate (wash, rinse / dry). When the cycle is complete the Clean LED will be illuminated.
TO CANCEL A CYCLE:
Press the Power Scrub Plus and Regular Wash Buttons both in at the same time. The unit will then drain and the Clean LED will illuminate.
Please note: If the door is opened during the cycle, the On/Off Button will be reset to off and must
be depressed again to re-active the cycle. The cycle will resume from where it left off.

H
First depress the On/Off Button until it locks in place.
Fig. 3-6.
Once the On/Off Button is depressed the LED above the previously used cycle will illuminate. To change the cycle, simply press the desired Cycle Button twice. The LED above that cycle will then illuminate.
The Cycle Countdown will display an approximate run time for the cycle chosen. This run time will depend on incoming water temperature and the turbidity of the pre-wash water.
Note: It is normal for the Countdown Display to remain at a time increment for more than one minute, or skip a time increment
depending on the calculations of the Control Unit.
Also, with continued use the Control Unit will learn the wash and temperature patterns for the most commonly used programs and will then reduce the overall start and running times.
At the end of the cycle the display will show a CL, indicating that the cycle is complete.
TO CANCEL A CYCLE:
Press the Scrub Wash and Delicate / Econo Buttons both in at the same time. The unit will then drain and the figure CL will appear in the display.
DELAY START:
The Delay Start feature allows the unit to be delayed for up to nine hours. To program, start the unit as described above, but after selecting a cycle push the Delay Start button. The display will show a 1h, or one-hour delay. Continue to depress the Delay Start Button until the desired delay time is reached (up to nine hours, 9h).
The unit will begin automatically once the delay time has elapsed. To reset the delay, press the Delay Start Button until it reaches 0h.
REFILL RINSE AGENT LED:
The Refill Rinse Agent LED is activated via a Reed Switch on the Detergent Dispenser, Section 4, Fig. 8-3. The LED will illuminate when the Rinse Agent Dispenser is empty.
Service note: The Refill Rinse Agent LED will also illuminate when the dishwasher door is opened and then
closed even if the Dispenser is full, but will only remain lit for a few seconds.
F CODE:
An F in the display window indicates a filling fault, see Section 6, Fig. 12-1 through Fig.12-6.
Please note: If the door is opened during the cycle, the On/Off Button will be reset to off and must be depressed again
to re-active the cycle. The cycle will resume from where it left off.

Rack System
Rack configurations for individual dishwasher models will vary. However, all Racks are constructed from a steel wire grid with a gray nylon outer covering.
Note: Racks may discolor due to the water
supply or types of food remaining on the dishes. We recommend that a vinegar wash be used to assist in removing these stains.
Start the unit, and let run approximately ten minutes, then pour in two cups of white vinegar and let the unit complete the cycle, repeat if necessary.

On select models the Upper Rack is height adjustable. To adjust rack height, or to remove the Rack from the unit.
Fully extend the Rack as shown in Fig. 4-2
With the Rack fully extended. Lift up on the Rack until the Front Rollers disengage from the Rail.
Now bring the Rack out further and allow the Rear Wheels to disengage.
Note how the Rack Rollers are designed to ride on the outside of the Rails for a smoother operation.
Rollers: Rack Rollers are a press fit making
for easy removal and replacement.

The Door Gasket is press fit into a channel molded around the Tank.
Note: Two inches of overlap are left at each end
of the Gasket to insure a proper seal.
Service tip: To test for a bad Door Gasket, open the dishwasher door and insert a dollar bill, then
close the door and pull the bill out. If the bill is snug the Gasket is good, if the bill slides out easily the Door Gasket may need to be replaced.
To remove the Gasket, simply pull it away from the Tank Channel.
To replace, press the ribbed end firmly into the channel until secure. No sealant or glue is required.

To remove the Arm, grasp the Arm Hub and pull up until the Arm disengages from the Socket.
The Arm or Arm Socket can now be checked for debris.
Fig. 5-9 The Filter Basket is removed by turning it ninety degrees counter-clockwise.
Fig. 5-10 Then lift it out for cleaning.
The Filter is a fine mesh of stainless steel and should be inspected and cleaned at least once a month.
Fig. 5-11 With the Filter Basket removed, the filter screen can then be lifted out.
The Filter Screen is also made of stainless steel, and was designed with rolled ends to eliminate sharp edges. It too should be inspected and cleaned at least once a month.
Fig. 5-12 With the Filter Screens removed you now have access to the sump area.
The Sump has a Drain Intake on the left, and the Circulation Pump Intake on the right.
A removable cover, item 1, hides the Drain Impeller. To remove the cover, remove the single T-20 Torx screw and then lift the cover off. You may now examine the Impeller for any obstructions.
The Feeder Tube Assembly allows water to flow to the Lower, then Upper Spray Arms and then to the Top Sprayer Head. It is replaced as a complete assembly by first removing the two T-20 Torx screws, item 2, at its base.
Then bring the tube up and off the Sump Housing, and remove it from the retaining clip located on the rear wall.
