When to Purchase a Cove Dishwasher Water Softener Model


  • At what water hardness level should a softener unit be considered?
  • How hard does water have to be to purchase a Cove Dishwasher with a water softener?
  • When to purchase a Cove water softener model
  • If I have a whole house water softener, is this model needed?


A Cove water softener model will benefit customers in areas with hard water, or those without a home water softener.

  • Customers with a water hardness over 5 grains should consider selecting a water softener unit to increase performance in both cleaning and drying.
  • There is no additional benefit for buying a Cove with a built-in softener, unless the whole house system was not operating at peak performance.
  • Some contractors plumb the kitchen sink with non-softened water for drinking, so if the dishwasher would tap off of this, the water softener unit would be beneficial.
  • See also, Cove Dishwasher Water Hardness Setting for more information.
  • Refer to Cove FAQs for more information.
