Limescale and cleaning: how to keep your coffee maker running smoothly.

Limestone accumulates over time and can:

• increase the warm-up time

• affect the taste

• cause blockages and odors

1) Signs of limestone

• coffee taking longer to make

• strange smells

• white deposits inside/jar

• irregular flow (in some cases)

2) Electric coffee maker (filter): simple routine

Daily cleaning

• Wash pitcher and filter holder

• Remove coffee residue (prevents odor).

Descaling (when necessary)

• Run a cycle with a descaling solution (diluted vinegar or a suitable product).

• Then run two cycles with clean water only to rinse thoroughly.

✅ The harder the water and the more daily use, the more frequent descaling will occur.

3) Moka pot: proper cleaning (without damaging it)

• Always rinse and dry after use.

• Check the gasket/seal and replace it when it is hard/cracked.

• Avoid harsh detergents (many people prefer just hot water; if you use detergent, rinse very well to avoid leaving a taste).

4) Common mistakes

• Do not rinse well after descaling → strange taste

• Let old coffee grounds dry inside → smells and tastes "old"

• Ignoring the gasket/seal on the Moka pot leads to loss of pressure and worse coffee.

FAQ

How often should I descale my electric coffee maker?
It depends on the water hardness and usage. If you notice sediment or the coffee starts taking longer to brew, it's time to return it.

How do I know if the Moka gasket needs replacing?
If it's hard, cracked, leaking, or if the coffee loses strength/extraction, it's usually a sign.
