Descale Information

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.

  • Descale message will flash when unit sits idle or when program is changed.
  • 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.
    • Water hardness is an adjustable setting with four water hardness setting options.
    • One is low water hardness, and four is high water hardness.

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

Descaling Tips

  • Descaling takes about 45 minutes.
    • It does require the user to be in front of the unit for the entire descale process.
    • Wolf suggests descaling as soon as the message appears.
  • Descaling frequency varies by use and water hardness.
  • The use of a descaling solution other than EcoDecalk may result in the descale message appearing more frequently.
  • The Coffee System will work without descaling, but taste and functionality are compromised until the system is descaled.
  • EC24 Coffee Systems do not include descaling solution due to the chemicals in the solution.


  • If the descaling message appears when the descale is complete, descale the machine again, as it did not descale properly.
  • If the unit does not start descaling, turn the power off and reset the circuit breaker. If the descale still does not work 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.
