Quick Guide for Bosch Dishwasher
This guide provides essential tips and tricks for operating and maintaining your Bosch 24-BOS-1812 dishwasher to ensure optimal performance.
Loading and Rack Adjustments

- 3rd Rack: Use the 3rd rack for silverware, large utensils, or other hard-to-place items.
- Rackmatic System: The middle rack height can be adjusted in 9 different positions. To adjust, pull out the middle rack, press the side levers, and move each side up or down to the desired position.
- Loading Dishes: Face dishes inward. Utilize angled tines to assist with loading and fold down flip tines to accommodate bulkier items like large pots.
Maintenance and Cleaning
- Filter Cleaning: Clean the dishwasher filter every 2 months with normal use. Turn the knob, lift the filter out, and wash it by rinsing with warm water and dishwashing soap.
- Surface Cleaning: Clean dishwasher surfaces using a damp cloth and mild soap. Do not use abrasive or bleach-based cleaners.
Operational Tips
- Pre-rinsing: With Bosch PrecisionWash and the PowerControl spray arm, there is no need to pre-rinse dishes. Simply scrape off food and place them in the dishwasher.
- Water Temperature: Set your water heater temperature between 120 and 125 degrees F. If the temperature is too high, the soap may not activate and perform properly.
- Starting a Cycle: Press the On/Off button, select your desired cycle and option, then press Start. Ensure nothing is blocking the spray arms before starting.
- Drying: Bosch dishwashers offer enhanced drying options like AutoAir, CrystalDry, or PureDry. PureDry whisks moisture away as dishes cool without an exposed heating element. Condensation on tub walls is normal.
- Detergent and Rinse Aid: Bosch recommends using Finish detergent tabs and Jet-Dry Rinse Aid for best results.
