Dishwasher Cycle Options

Delay

Allows you to delay the start time of your dishwasher up to 24 hours.

Half Load

Can reduce water consumption when washing small, lightly soiled loads that fill approximately half or less of the dishwasher’s capacity.

Sanitize

Increases the temperatures and retains them for an extra long time to obtain a defined disinfecting performance. Continuous use of this function increases the hygiene status. This additional option is ideal for cleaning items such as chopping boards and baby bottles. “Sanitized” will appear in the display window when sanitation requirements are met. Using the Sanitize option may also improve drying. There is a slight increase in energy consumption.

Extra Dry

Used in combination with a wash cycle (except Rinse), the Extra Dry option raises the temperature and extends the drying time to further enhance drying results and provide a brilliant shine. The energy usage may be increased.

ExtraScrub®

This option increases pressure and temperature in the lower rack for intensive cleaning.

Wash Cycle Information

To save energy, this dishwasher has EcoSense where the sensors in the dishwasher automatically adjust the cycle length, temperature and water changes based on the amount of food soil and the incoming water temperature. The “Smart Control” makes decisions that can cause the cycle time and water usage to adjust intermittently. Wash cycle times are based on 120°F (49° C) water supply. If your household water supply is different than 120°F (49° C), your dishwasher’s cycle times may be impacted.

Note: Only sanitizing cycles have been designed to meet the requirements of Section 6 of the NSF/ANSI Standard for Residential Equipment for soil removal and sanitization efficacy. There is no intention, either directly or indirectly, to imply that all cycles have passed sanitization performance tests.

Note: Some of the wash cycles and options will vary by model.

Operating the Dishwasher

Protection against unintentional operation

Your dishwasher is equipped with a function that helps to prevent unintentional operation (e.g. by children).

After starting the dishwasher, the dishwasher door has to be closed within 4 seconds, otherwise the operation will be paused. There will be a signal on the control panel advising you to press the Start button again and close the door. This function will be activated when:

• pressing Start to begin a wash cycle
• setting Delay time and pressing Start
• opening the door while Delay time is active
• opening the door during a wash cycle.

Note: This function cannot be deactivated.

AquaSensor

The AquaSensor is an optical measuring device which measures the cleanliness of the rinse water. The AquaSensor is used according to the wash cycle. If the AquaSensor is active, “clean” rinse water can be transferred to the next rinse and water consumption can be reduced by 0.8–1-5 gal (3–6 liters). If the rinse water is not yet clear, the water is drained and is replaced with fresh water. In the automatic wash cycles the temperature and running time can also be adjusted to the degree of soiling.

Switching the appliance on

1. Turn the water supply on fully.

2. Press the On/Off button 1. The display of the last selected wash cycle flashes. This wash cycle remains selected if no other wash cycle button 2 is pressed. The expected wash cycle duration flashes on the display 3. Select any desired option.

3. Press Start button 6. Wash cycle sequence starts.

Note: Your dishwasher is protected against unintentional operation. If the appliance door remains open for more than 4 seconds after pressing the Start button, the operation will be paused. Press the Start button again and close the appliance door.

Time display

When a wash cycle is selected the remaining wash cycle time is shown on the display 3. The wash cycle time is determined during the wash cycle by the water temperature, the amount of dishes, as well as the degree of soiling and may vary (depending on the selected wash cycle).

To change the signal volume:

1. Open the door.

2. Press the On/Off button 1.

3. Hold down function key A and press Start button 6 until the display 3 indicates (x can be any number). Release both buttons.

4. Press function key A until the display shows

5. Press function key C. Each time the button is pressed the set value increases by one level; when it reaches the value the display jumps back to (off).

6. Press Start button 6 to save the setting.

Care and Maintenance

A regular inspection and maintenance of your machine will help to prevent faults. This saves time and prevents future problems.

Cleaning the dishwasher

• Regularly wipe the front of the appliance with a damp cloth - water and a small amount of liquid soap is adequate.
• For black stainless steel and anti-fingerprint surfaces, use a soft, dry towel. For stubborn dirt, use warm water diluted with a non-abrasive, mild cleansing soap. Never use stainless steel polish.
• For stainless steel appliances (excluding black stainless and anti-fingerprint), use a stainless steel polish to seal and protect the surface.
• Clean the outer edges of the inside door panel regularly to remove debris that may collect from normal loading. If spots begin to appear on the stainless steel, make sure the rinse aid dispenser is full and functioning properly.
• Clean the door seal regularly with a damp cloth to remove food particles that may collect from normal loading and cause odor. A soiled door seal may not seal properly.

NOTICE

• Never use a steam cleaner to clean your dishwasher. The manufacturer is not liable for any resulting damage.
• Do not use sponges as they could scratch the surfaces.
• Do not use bleach-based wipes as they could damage the surface or printing.
• Never use stainless steel polish on a black stainless finish or anti-fingerprint surfaces.

Filters

The Bosch® filter system 28 is designed to prevent the need to pre-rinse normally attached food soils from your dishes. Simply scrape leftover food soils off of dishware before loading. This process will conserve time, water and the energy require to heat your household water supply.

Your dishwasher filter system is designed to filter 100% of the water entering the spray arms to provide a continuous supply of clean water to remove food soils from your dishware.

Filter components

The filter system 28 consists of three parts.

A Large Object Trap

Trap Prevents objects that should not be placed in your dishwasher from damaging the dishwasher pump system or clogging your household drain.

B Flat Fine Filter

Prevents food particles from entering the wash chamber and directs particles toward the micro filter.

C Micro Filter

Directs the smallest of particles to the household plumbing drain.

Cleaning intervals

The filter system 28 is designed to minimize maintenance while providing premium cleaning performance and minimum energy consumption. Depending on use habits and water hardness, the filter system will require some maintenance to sustain premium cleaning performance. Your filter system may need to be cleaned when:

• You notice food soils remaining on the filter system or objects trapped in the Large Object Trap.
• A drop in cleaning performance or a gritty film forms on the dishware.

When washing normally attached food soils that have been scraped before loading, in a household that runs the dishwasher every other day, your filter should be cleaned:

Note: Clean the filter system after washing loads with large amounts of food soils or loads with a heavy starch content, like potatoes and pasta, to maintain optimal performance.

Drain pump

Large food remnants in the rinsing water not retained by the filters may block the waste water pump. In this case:

• Disconnect the appliance from the power supply.
• Remove the filters. "Filters" on page 36
• Scoop out standing water - use a sponge if necessary.
• Using a spoon, pry off the pump cover until it clicks, then grip the cover and pull upward until it resists and then pull forward.

• Check inner compartment and remove any foreign objects.
• Place cover in the original position, press down and engage.
• Reinstall filters.

Note: The drain pump will not work properly if the drain pump cover is not snapped in completely until it clicks.

Preparing your unit for vacation

NOTICE

Before leaving for vacation during warmer weather, besides turning off the main valve, also turn off water supply at the nearest point to the dishwasher. Do not leave soiled dishware in unit and leave door slightly open. During colder weather, please follow the instructions for winterizing your unit below.

Winterizing your unit

NOTICE

If your dishwasher will be unused for a period of time in a location that experiences freezing temperatures (holiday home or through a vacation period), have your dishwasher winterized by a professional service.
