Gaggenau Coffee System Descale Warning Not Clearing
Coffee System Descale Warning Not Clearing is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Mineral scale buildup
Hard water leaves mineral deposits in the water lines and steam generator that reduce performance over time.
A failed water level sensor
Can prevent the unit from generating steam even with a full reservoir.
A clogged water inlet or line
Restricts the water supply the steam system needs to function.
Local conditions that matter here
Las Vegas water runs about 16 grains per gallon — genuinely hard, and among the hardest municipal supplies in the country. Anything plumbed here accumulates mineral faster than the manual assumes: fill valves narrow, heating elements fur, and output tapers off over months rather than stopping outright.
