Loading Your Dishwasher Correctly
Optimal loading is crucial for spotless results! Avoid overcrowding; dishes should not nest or block spray arms. Face soiled surfaces towards the center. Ensure tall items don’t impede upper rack rotation. Proper loading maximizes water circulation and cleaning power.
Prioritize safety by securing sharp objects, like knives, point-down in the cutlery basket. Check spray arm clearance before starting a cycle. Incorrectly loaded items may not be fully cleaned and could cause damage. Refer to the detailed rack loading guides for specific placement recommendations.
Upper Rack Loading Guidelines
The upper rack is designed for glasses, cups, small plates, and delicate items. Ensure items are securely placed in the racks to prevent movement during the wash cycle. Avoid placing items directly over the lower spray arm, as this can hinder its rotation and reduce cleaning effectiveness.
Adjustable tines allow for customization to accommodate various dish sizes. Fold down tines to create space for larger items like bowls. Always check that spray arms can rotate freely after loading. Properly loaded glasses will emerge sparkling and spot-free!
Lower Rack Loading Guidelines
The lower rack is best suited for larger, heavier items such as pots, pans, and dinner plates. Face soiled surfaces towards the center of the dishwasher for optimal cleaning. Ensure tall items do not obstruct the spray arm’s rotation; adjust the rack height if necessary.
Securely position plates and bowls to prevent them from shifting during the wash cycle. Avoid overcrowding, allowing water to reach all surfaces. Larger items should be placed along the sides and back, leaving space for water circulation. Proper loading ensures thorough cleaning!

Cutlery Basket Usage
The cutlery basket is designed to hold forks, knives, and spoons safely and effectively. Alternate utensil placement – handles down for forks and spoons, handles up for knives – to prevent nesting and ensure thorough cleaning. Utilize the individual slots or dividers within the basket to separate items.

Avoid overloading the basket, as this can hinder water circulation and result in poorly cleaned cutlery. Long utensils may need to lie flat. Check after the wash cycle to ensure all items are clean; redistribute if needed for future cycles;
Detergent, Rinse Aid & Special Salts
Optimal dishwasher performance relies on using the correct cleaning agents. Always use dishwasher detergent specifically formulated for automatic dishwashers; hand soap will create excessive suds. Rinse aid minimizes water spots and enhances drying, while special dishwasher salt softens hard water, preventing limescale buildup.
Proper levels of each are crucial. Refer to detergent packaging for dosage instructions based on water hardness and soil level. Regularly check and refill rinse aid and salt compartments as indicated by the control panel’s warning lights.
Recommended Detergents & Amounts
Bosch dishwashers perform best with high-quality detergents. We recommend using powder, gel, or tablet detergents specifically designed for automatic dishwashers. Avoid detergents containing chlorine bleach to protect internal components.
Dosage varies based on water hardness and the level of food soil. For soft water, use approximately 1.5 tablespoons (20ml) of powder or gel, or one tablet. Medium hardness requires 2 tablespoons (30ml) or one larger tablet. Hard water needs 2.5 tablespoons (37ml) or two tablets. Always consult the detergent packaging for specific guidance.

Rinse Aid: Purpose & Refilling
Rinse aid is crucial for achieving spotless, streak-free dishes and faster drying times. It works by reducing surface tension, allowing water to sheet off dishes instead of forming droplets. A lack of rinse aid can result in water spots, especially in hard water areas.
To refill, locate the rinse aid dispenser, typically near the detergent compartment. Open the dispenser cap and carefully pour in rinse aid until the indicator window shows it’s full. Adjust the dosage setting (usually 1-6) based on your water hardness; higher numbers for harder water. Regularly check and replenish as needed.
Special Salt: When & How to Use (Water Hardness Settings)
Dishwasher salt is essential if your water is hard, preventing limescale buildup which can damage your dishwasher and reduce cleaning performance. Hard water contains minerals that leave deposits. The salt softens the water before it enters the wash cycle.
To use, remove the lower rack and locate the salt reservoir. Fill it with dishwasher salt (do not use table salt!). Use the setting tool to adjust the water hardness level – consult your local water authority for hardness information. Regularly check the salt level and refill as needed; a low salt indicator will illuminate.
Running a Wash Cycle
Before starting, ensure the dishwasher is properly loaded, detergent and rinse aid are filled, and the door is securely latched. Select your desired wash cycle based on the load type and soil level – options range from Auto to Heavy Duty.
To begin, press the Power button, then press the Start button. The display will show the remaining cycle time. You can pause the cycle at any time by pressing the Start button again. To cancel, press and hold the Start button for three seconds. Avoid interrupting cycles unnecessarily to maintain efficiency.
Selecting the Appropriate Wash Cycle
Your Bosch SilencePlus offers several cycles for optimal cleaning. Auto intelligently adjusts for soil level. Normal is ideal for everyday use. Eco saves water and energy. Quick Wash is for lightly soiled dishes needing a fast clean. Heavy Duty tackles baked-on foods.
For delicate items, use the Glass cycle. Sanitize provides extra hygiene. Consider the Half Load option for smaller loads to conserve resources. Refer to the cycle chart in the full manual for detailed descriptions and recommended usage scenarios for each available wash cycle.
Starting & Pausing a Cycle
To begin a wash cycle, ensure the dishwasher door is fully latched. Press the Start button; the display will show the remaining cycle time. To pause during operation, press the Start button again. The cycle will halt, and the light will flash.
To resume, press Start once more. Avoid interrupting mid-cycle unless necessary, as this may affect cleaning performance. If you need to add an item, pause the cycle, carefully add the dish, and restart. Remember to always check for proper water drainage before opening the door.
Troubleshooting Common Issues
Encountering problems? This section addresses frequent concerns. If the dishwasher won’t start, check the power supply and door latch. Poor cleaning often results from improper loading, insufficient detergent, or clogged filters. Leaking can stem from a loose connection, overfilling, or a damaged door seal.
