Installation Guide
Proper installation ensures optimal performance and longevity of your Bosch 800 Series dishwasher; carefully follow the provided manual’s instructions for water, drain, and electrical connections.
Unpacking and Inspection
Upon delivery, carefully inspect the Bosch 800 Series dishwasher for any visible damage incurred during transit. Retain all packaging materials until you’ve confirmed the appliance functions correctly. Gently remove the shipping restraints and protective films, noting their locations for potential future use.
Verify all included components against the parts list in the installation manual – this typically includes drain hose, water supply line, and installation hardware. If any parts are missing or damaged, immediately contact your retailer or Bosch customer support. Ensure the dishwasher’s exterior is free from scratches or dents before proceeding with installation. Document any pre-existing damage with photographs for warranty claims.
Water Supply Connection
Before connecting the water supply, ensure your home’s water pressure falls within the dishwasher’s specified range (typically 20-120 psi). A shut-off valve is essential on the hot water line for easy maintenance and emergencies.

Always double-check the voltage requirements before proceeding;
Securing the Dishwasher
Properly securing your Bosch 800 Series dishwasher is crucial for stable operation and preventing movement during cycles. Locate the mounting brackets provided with the unit. These brackets attach to the underside of your countertop or adjacent cabinetry. Use appropriate screws – typically wood screws – suited for your counter material.
Align the dishwasher with the opening, ensuring it’s level. Attach the mounting brackets to both the dishwasher and the countertop/cabinetry. Tighten the screws firmly, but avoid over-tightening, which could damage the cabinetry. A securely mounted dishwasher minimizes vibration and noise, contributing to a quieter and more efficient cleaning experience.

Position dishes and cookware so water reaches all surfaces. Avoid nesting bowls or stacking plates tightly. Secure lightweight items to prevent movement during the wash cycle. Following these guidelines ensures efficient water circulation and thorough cleaning, preventing re-washing and maximizing the dishwasher’s effectiveness for sparkling results every time.

Maintenance and Cleaning
Regular maintenance ensures optimal performance and longevity of your Bosch 800 Series dishwasher, including filter cleaning and spray arm inspections.
Cleaning the Interior
Maintaining a clean interior is crucial for optimal dishwasher performance and preventing odors. Regularly wipe down the dishwasher’s interior surfaces with a damp cloth and mild detergent. Pay particular attention to the door gasket, ensuring it’s free of food particles and debris to maintain a proper seal. Bosch recommends avoiding abrasive cleaners, as they can damage the stainless steel interior. For stubborn stains or buildup, a dishwasher cleaner specifically designed for Bosch appliances can be used, following the product’s instructions carefully. Remember to rinse thoroughly after using any cleaning product. Consistent interior cleaning contributes to hygienic dishwashing and extends the life of your 800 Series dishwasher.
Filter Cleaning Procedures
Regular filter cleaning is essential for preventing clogs and ensuring efficient dishwashing. The Bosch 800 Series dishwasher features a self-cleaning filter system, but periodic manual cleaning is still recommended. Locate the filter assembly, typically at the bottom of the dishwasher’s interior. Unlock and remove the filter components – usually a cylindrical filter and a flat filter. Rinse these parts thoroughly under running water, removing any food particles or debris. A soft brush can aid in dislodging stubborn residue. Reassemble the filter components correctly and securely lock them back into place. Bosch suggests checking the filter at least monthly, or more frequently with heavy use.
Spray Arm Inspection and Cleaning
Maintaining clean spray arms is crucial for optimal cleaning performance in your Bosch 800 Series dishwasher. Periodically inspect the upper and lower spray arms for any blockages caused by food particles or mineral deposits. Carefully remove the spray arms – they usually snap or unscrew easily. Use a toothpick or small wire to clear any clogged spray nozzles. Rinse the spray arms thoroughly under running water to remove dislodged debris. Ensure the spray arms rotate freely after cleaning. Reattach the spray arms securely, verifying they are properly aligned. Bosch recommends inspecting and cleaning spray arms every six months, or as needed, to maintain peak efficiency.
Exterior Cleaning and Care
To preserve the appearance of your Bosch 800 Series dishwasher, regular exterior cleaning is recommended. For stainless steel models, use a Bosch stainless steel cleaner or a mild dish soap diluted in warm water. Apply with a soft cloth, wiping in the direction of the grain to avoid streaks. Avoid abrasive cleaners, as they can damage the finish. For black stainless steel, use a cleaner specifically designed for this finish. Wipe down the control panel with a damp cloth. Regularly clean the door edges and handle to remove fingerprints and smudges. Bosch advises against using harsh chemicals or scouring pads, ensuring a lasting, pristine look.
