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.

Fig. 3-5

Fig. 3-6

The SHU 53** series operates using an electronic Control Unit.

TO OPERATE:

Fig. 3-5.

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.

The Bosch Sensotronic™ will reduce water consumption by approximately 20%, in the case of lightly soiled dishes. When Top Rack Only™ feature is used the water consumption is reduced approximately 30%. Shown above are the range of values that may be obtained while running the dishwasher under normal conditions. Actual values may vary. The actual cycle duration, water and energy usage are dependent upon inlet water temperature and amount of soil on dishware.

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.

Fig. 4-1

Fig. 4-2

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

Note how the Rack Rollers are designed to ride on the outside of the Rails for a smoother operation.

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.

Rollers:	Rack Rollers are a press fit making
	for easy removal and replacement.
