Bosch dishwasher regeneration salt
Bosch part 00311859 (granulated dishwasher salt, 3.3 lbs) is the manufacturer-recommended softening salt for Bosch dishwasher salt reservoirs. Compatible third-party alternatives include Finish Powerball Dishwasher Salt and Miele Dishwasher Salt, both meeting the minimum 99.5% NaCl purity requirement. Approximate price: $8-20 per 3.3-pound bag. Purchase from appliance retailers, grocery stores in areas with European dishwasher adoption, or online. At hardness level 5 with daily use, plan for approximately 1 bag per month. At hardness level 3, consumption reduces to approximately 1 bag every 6-8 weeks.
Salt reservoir cap and funnel
The salt reservoir cap (Bosch part 00165967 or equivalent, depending on model year) is a screw-top component with an integrated gasket. The gasket prevents wash water from entering the salt reservoir during the wash cycle. If the cap is cracked or the gasket is damaged, brine dilution can occur, reducing softening effectiveness. Replacement caps cost $10-20 and are available from authorized Bosch parts distributors. The included salt funnel (part 00266380) simplifies salt loading without spillage into the tub; replacement funnels cost $5-10 and are available from Bosch service parts suppliers.
Bosch UltraClarity Pro refrigerator filter
Part number 11034151 (UltraClarity Pro, NSF 42/53 certified) fits the majority of Bosch counter-depth and standard refrigerators produced after 2017. Check the model-specific compatibility list at the Bosch appliance website before ordering. Filters are rated for approximately 80 gallons or 6 months at the recommended 0.5 GPM dispense flow. Price: $35-50 at appliance retailers, Bosch authorized service centers, and online. Bosch refrigerator models display a filter replacement indicator at the 6-month mark. Actual filter life in hard water or high-chloramine areas may be shorter.
Descaler tablets for Bosch appliances
For descaling Bosch dishwashers and washing machines that have accumulated scale despite softening, Bosch recommends Bosch Descaler (part 00312294) or Miele Descaler as compatible products. Descaler tablets dissolve citric acid (or a proprietary acid blend) in the wash water, dissolving calcium carbonate deposits from heating elements and spray arms. For dishwashers, add one descaler tablet to the tub (not the detergent drawer) and run a hot cycle without dishes. For washing machines, add the descaler to the drum and run an empty cotton 90-degree cycle. Repeat every 3-6 months if the whole-house water is not fully softened.
