Fig. 2-1

The Bosch dishwasher utilizes a two motor system with separate Circulation and Drain Motors, and aFlow Through Heater controlled by a Flow Switch and NTC Thermistor. With some models also havingthe 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 overallsize and energy consumption. While also reducing operating noise.

• The Flow-Through Heater allows a shorter heating cycle since all water must pass through theHeater, increasing water temperature by approximately two degrees a minute. To protect theheater 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 watertemperature increases the NTC records the decrease in resistance. The Control Unit Logic Boardmeasures this resistance change and allows the program to advance once the correcttemperature (resistance level) is reached.

• The Aqua Sensor turbidity measuring device, which is available only on select models, evaluatesthe pre-wash water using a beam of light and a pick-up sensor. If the beam passes easily throughthe 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 anupper and lower spray arm as well as an overhead sprayer, Fig. 2-2.

Washability / Drying

WASHABILITY

There are four factors that play a critical role in Washability: Time, Temperature, Water and Detergent. Itis important when attempting to determine the cause of a Washability complaint that all four factors beconsidered and tested.

Time: The duration of the program is accurate (see cycle chart).

Temperature: The wash and rinse temperatures are within the desired range (see cycle chart).

Water: The unit is filling with the correct amount of water (Section 3, Fig.5-7)

Detergent: The detergent is fresh, and not being used in excessive amounts.

Please note: Other factors such as clean filters, a properly routed drain hose, water hardness andquality, as well as loading of items will also effect Washability.

DRYING

As part of an energy saving design Bosch Dishwashers do not activate the Heating Element during theDrying cycle. Instead, the dishwasher utilizes a rinse temperature of up to 161° Fahrenheit, and theaddition of Rinse Agent to achieve a quality drying result.

HOW THIS SYSTEM FUNCTIONS:

During the rinse cycle water is heated to 161° Fahrenheit, this heat is transferred to the items inthe dishwasher where it is absorb and stored.

During the drying portion of the cycle all dishwasher items will then radiate the stored heat, thusevaporating any water that has collected on the items surface, burning it off and converting theliquid into steam.

This process of “flash drying” is assisted by the release of Rinse Agent into the rinse water. RinseAgent is a water softener that inhibits water from collecting or pooling, allowing it to be easilyevaporated.

The remaining steam is vented from the interior through the Steam Vent (Fig. 6-4, item 2) where itis then collected by, and drained from the Condensation Tube (Section 4, Fig. 7-5, item 2).

Service note: When confronted with a drying complaint, make sure the Rinse Agent Dispenser is full,and the rinse water temperature is within the desired range. Please remember that theunit will not dry without Rinse Agent.

Water Inlet / Discharge System – Operation

WATER SYSTEM OPERATION: Fig. 12-1 is a close up view of the complete Water Systems.

FILLING

NORMAL OPERATION (Fig. 12-2)

Fresh water is brought in by the Water Valve and through the Inlet Water Line, item 3. Theincoming water is then directed into the Water Level Housing Assembly, item 4, and then on to theSump via the Sump Fill Hose, item 8.

As the unit fills with water the Diaphragm on the Water Level Housing Assembly expands due tothe pressure of air forced up by the incoming water. When the correct water level is reached theDiaphragm moves the Switch Lever, which in turn closes the Water Level Switch.

When the Water Level Switch closes the Water Valve shuts and the Circulation Motor is activated,and the program advances.

Note: Once the Circulation Motor is activated the water level will drop slightly, the unit thencalls for a small amount of additional water to be added.

OVER FILL (Fig. 12-3)

As a safety feature, if the Diaphragm were to malfunction the water level would rise and activatethe Safety Float, item 5. As the Safety Float rises it in turn closes the Float Switch, item 6. Whenthe Float Switch closes it activates the Drain Motor.

Service tip: If the dishwasher repeatedly fills and drains the cause is most likely a faultyDiaphragm.

BASE FLOAT (Fig. 12-4)

As an additional safety feature, if the Base were to fill with water due to a hose or pump leak theBase Float, item 9, will rise and via a Float Lever and Pushrod, item 8, would close the FloatSwitch, which in turn activates the Drain Motor.

Service tip: If there is water in the base the Drain Motor will run continually, but will not drainwater from the base.

“F” CODE

Dishwashers with a Countdown Display will show an “F” in the display window when a filling faultoccurs. Filling faults can be: Water in the base; overfill; and under or no fill.

Live Dealer Display Models with “F” codes:

Since display models are hand filled, achieving the correct water level is difficult, (see Section 3,Fig. 5-7) so the unit will perceive a filling fault and display the “F” code. This is normal, do notattempt a repair.

DRAINING

When the Drain Motor is activated gray water flows from the Sump through the Sump Drain Hose,item 2, around the Water Chamber and out through the Main Drain Line, item 1.

COMPONENT EXPLANATION:

Circulation Pump / Motor.

The Circulation Pump / Motor can be replaced from the right side by following the same accessprocedures for removal of the NTC outlined in the remainder of this section, and then by followingthe steps in Section 8, Figs. 16-2 through 16-7, for the Circulation Pump / Motor removal.

Service Note: Section 8, also gives and alternative removal method for the Circulation Pump / Motor.

Base Wiring Connectors.

The Base Wiring Connectors allow the Upper Wiring Harness to mate with the Base Wiring Harness.

Flow Switch.

Located between the two heater terminals is the Flow Switch. In the event that water does not flowacross the Heating Element, the Flow Switch disables the element. To remove the Flow Switch,bring the bottom of the switch out from its base, unhook the side tabs, and then lift the switch out.

Heater Assembly.

The Heater Assembly cannot be replaced from the side, but is accessible for continuity testing.Replacement of the Heater Assembly is outlined in Section 8, Figs. 16-8 through 16-12.

52 H

NTC Operation

Fig. 14-1

Located on top of the Heater Assembly is the NTC (Negative Temperature Coefficient), Fig. 14-1. TheNTC uses resistance to control wash and rinse water temperature and is connected with two green leads.

As water temperature increases, the NTC records the decrease in resistance. The Control Unit LogicBoard measures this resistance change and allows the program to advance once the correcttemperature (resistance level) is reached.

Service note: The SHU 30** and SHU 40** models do not use an NTC, but utilize a standard, normallyopen thermostat (bi-metal).

Also combined within the NTC (or standard thermostat) is a High Limit Safety Thermostat, connectedwith red leads. The normally closed high limit is set to 185° Fahrenheit and is self-resetting.

Service tip: The NTC can be checked without removing the dishwasher by measuring its resistance atthe Control Unit. Using the appropriate wiring diagram, locate the two NTC leads. Theresistance at room temperature should be approximately 55k Ohms.

An extremely high, low or no Ohm reading will usually indicate a faulty NTC.

CIRCULATION PUMP / MOTOR REMOVAL:

Disconnect the four wire leads, then grasp the Circulation Motor and turn clockwise a quarter turn untilthe Motor stops, Fig. 16-2. Now, remove the Motor / Rear Pump Assembly from the Front PumpHousing, Fig. 16-3.

Note: The Front Pump Housing remains in place when the Motor is removed, Fig.16-3, item 1.

With the Motor / Rear Pump Assembly removed from the unit, separate the Motor from the Rear PumpAssembly. To do so, first remove the Impeller by placing a block in the rear of the Motor and then turningthe Impeller counter-clockwise, then Fig 16-4.

The Rear Pump Assembly consists of four components, Fig. 16-5:

1. Rear Pump Housing. 3. Impeller.2. Main Pump Seal. 4. Impeller Seal.

Each component can be replaced as an individual item.

TO INSTALL:

First, locate the Key Square on the Front Pump Housing, Fig. 16-6. Next, locate the Key Square CutOut on the Rear Pump Housing, Fig. 16-3, item 2.

When replacing the Pump / Motor make sure to line up the Key Square with the Key Square Cut Out.Then bring the two pump halves together in the position shown in Fig. 16-2, and turn the Motorclockwise until it stops, see Fig. 16-7.

Service note: The Impeller Seal Spring is compressed when the two halves of the Pump Assembly arebrought together. This will take a little force, so make sure to have a good grip on theSump as you compress the spring.

Aqua Sensor

Fig. 16-13 Fig. 16-14

The Aqua Sensor turbidity measuring device, Fig. 16-13, 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 thebeam cannot pass through, then the pre-wash water is drained and a fresh fill is added for the mainwash cycle.

To replace the sensor, Fig. 16-14, slide it out from its housing located on the Heater Assembly.

Service note: Since the Aqua Sensor has no effect on washability, it should never be replaced. Only if aleak were to occur should service be performed on this component.
