Discoloration of silver or aluminium items after washing in the dishwasher

Issue:
  • Discoloration of silver or aluminium items after washing in the dishwasher
Applies to:
  • integrated dishwasher
  • freestanding dishwasher
Resolution:

1. Do not wash silver or aluminum items in the dishwasher. 

Aluminum and silver items can turn black due to air, sulfur and water reacting.

  • When these items are washed, black deposits are left on other items, the baskets, and the inside of the dishwasher.
  • Some silver items only have a thin coating of silver and are not recommended for washing in the dishwasher.
