The Coffee System flow meter counts the quantity of water used. When the quantity reaches the set limit according to water hardness, "Descaling" appears on the appliance display.

  • Water hardness is an adjustable setting with four water hardness setting options.
  • 1 is low water hardness and 4 is high water hardness.
  • There is no standard for how often a Coffee System requires descaling as it is based on individual use.
  • Refer to Coffee System Water Requirements for information on adjusting the water hardness level on the unit.

The Coffee System Quick Start Guide provided with the descaling solution details the descaling process.

  • Use only EcoDecalk descaling solution to descale the Wolf Coffee System.
  • Coffee System descaling solution, part number 824828, includes two bottles of EcoDecalk descaling solution.
    • EcoDecalk is an ecological descaler made with 100% lactic acid.
    • 16.9 fl oz bottles have four descaling uses each.
  • See also, Coffee System Care Kit.

Both cleaning kits are available for purchase from a Wolf Dealer, Factory Certified Parts Distributor, or through Wolf’s Accessory Store.

Descaling Tips

  • Descaling takes about 45 minutes.
  • Wolf suggests descaling as soon as the message appears.
  • Descaling frequency varies by use and water hardness.
  • Using a descaling solution other than EcoDecalk may result in the descale message appearing more frequently.
  • If the descaling message displays as soon as the descale is complete, descale the machine again, as it did not descale properly.
  • If the unit doesn't start descaling, turn the power off and reset the circuit breaker. If the descale still does not function properly, contact Factory Certified Service to schedule an appointment for repair.
  • If descaling message appears before expected, verify the water hardness setting. See Coffee System Water Requirements for more information.
  • The Coffee System will work without descaling, but taste and functionality are compromised until the system is descaled.
  • Descaling solution is not included with EC24 Coffee Systems due to the chemicals in the solution.
