Summary answer
Most coffee makers should be descaled on a regular schedule based on water hardness, usage, and the manufacturer instructions.
Key takeaways
- - Hard water requires more frequent descaling.
- - Slow brewing can be a warning sign.
- - Always follow the machine manual.
What descaling does
Descaling removes mineral buildup that can slow water flow, affect taste, and shorten machine life.
How to choose a schedule
Use the manual as the baseline. Increase frequency if you brew daily or live in a hard-water area.
Signs you waited too long
Slower brewing, unusual noise, reduced water flow, or inconsistent temperature can point to mineral buildup.
