Descaler

What it is and what sets it apart: Not group detergent/backflush—it attacks precipitated carbonates. Filters prevent; descaler corrects.

What it’s for and how to use it: Follow the manual → don’t mix with backflush detergent → rinse until taste is clean.

Cup impact or benefit: Stable temp/pressure and longer machine life.

Technical notes: Frequency follows hardness and litres. Rinse thoroughly.

Common mistakes: Vinegar without proper rinse. Skipping when scale is visible.
