SYMPTOM

Residual heat too high - descaling cannot start

Appliance: V-ZUG Combi-Steam Models: CSTXSL60F, CSTXSL60FY, CSSL, CSSL60c, CSSL60Y

What This Means

An acoustic signal is emitted and the display shows Residual heat too high. The appliance has not cooled down sufficiently to begin the descaling process. Descaling requires a cold appliance.

🔧 How to Fix

  1. Allow the appliance to cool down completely before attempting descaling again.
  2. Do not run any operating mode beforehand; let it sit idle with the door slightly open to speed cooling.
