      To prevent discoloration of stainless steel, silverplate, or sterling silver in your Viking dishwasher: * Rinse flatware that is to stand several hours before washing to remove salty foods. * Do not put stainless steel and silver flatware in the same silverware basket compartment, as direct contact between these metals can cause permanent damage to silver. * Clean stained items with silver polish, but do not use abrasives on stainless steel or silver.

      Nicholas MartinezAug 23, 2025
      If your dishes are not drying in your Viking dishwasher, consider the following: * If you're using a non-heat drying option, allow more drying time. * Fill the rinse agent dispenser, as rinse agent helps dishes dry faster. * Be aware that certain plastic materials are difficult to dry and may need towel drying. * Avoid overloading or nesting items, ensure all surfaces drain well, and load items with concave bases so water can run off. Unload the lower rack first to prevent water from the upper rack spilling onto the lower rack.

    Why are there small particles deposited on items after washing in my Viking Dishwasher?
    • E
      Emily BaileySep 4, 2025
      If you notice small particles deposited on items after washing in your Viking dishwasher, it could be due to: * Using old detergent. Use only fresh detergent, stored in a tightly closed container in a cool, dry place. Fill the dispenser just before starting the dishwasher and use the recommended amount, especially with hard water. * Dishes not loaded properly, preventing water and detergent from reaching all surfaces. Ensure water can circulate freely. * Flatware loaded incorrectly, such as spoons nesting together and preventing water penetration. * A clogged filter due to heavy sediment, food soil, or hard water conditions.
