Mineral scale care

Coffee machine descaling

Descaling removes mineral build-up from the water path. The chemistry is only one part of the job — the machine-specific programme, rinse stages and filter sequence matter too.

Understand the jobFind my machine
WHAT THIS JOB IS FORDescaling targets limescale and mineral deposits in the water system. It is not the same as removing coffee oils from the brew path.

When it comes up

When should you think about descaling?

01

The machine displays a descale or Calc/Clean prompt.

02

Your manufacturer sets a water-hardness or usage-based descale interval.

03

Flow or heating performance has changed and scale is a plausible maintenance cause.

The safe general approach

The machine procedure still wins.

Use this as orientation. The exact controls, product placement and programme sequence should come from your model-specific guide.

01

Check the exact model procedure before adding any product.

02

Remove or manage the water filter in the order specified for your machine.

03

Use the correct amount of coffee-machine descaler and water for the programme.

04

Let the entire descale and rinse sequence finish before treating the job as complete.

Important

Do not put cleaning tablets in the water tank as a substitute for descaler, and do not keep repeating descale cycles when the machine has just completed one correctly.

Something not going to plan?

Troubleshoot the symptom, not the guess.

If a warning will not clear or a programme behaves differently from expected, start with the symptom before repeating the maintenance job.

Keep the jobs separate, but connected.

Incoming water care

Water filtration

A water filter can reduce scale exposure, but it does not clean coffee oils and it does not automatically cancel a descale programme that is already due.

Open guide →Coffee residue care

Cleaning

Cleaning removes coffee oils, grounds and milk residue. Descaling removes mineral deposits from the water system. They are different maintenance jobs and usually use different products.
