9. WATER HARDNESS
The descale indicator (B10) lights up following a predeter-
mined period of operation that depends on a water hardness
setting. The machine can also be programmed according to the
actual hardness of the local water supply, in which case descal-
ing may be required less frequently.
1. Remove the "TOTAL HARDNESS TEST" indicator strip (C6)
from its pack.
2. Immerse the strip completely in a glass of water for about
one second.
3. Remove the strip from the water and shake lightly.

10. HOW TO USE SOFTBALLS
Softballs (C10) are an innovative treatment system able to prolong
the life of the machine, without altering the properties of the
water, while ensuring consistently creamy and aromatic coee.
To optimize the eectiveness of the treatment, leave Softballs in
water overnight before use.
1. Take the Softballs sachet from the wrapper (g. 37).

2. Rinse the sachet under running water (g. 38).

39).

4. Replace the sachet of Softballs every 3 months (g. 40).
11. DESCALING
Important!
• Regular descaling will ensure that optimum results are
obtained over time: when a prompt is generated by the
machine, purchase Ecodecalk on the delonghi.com website
and proceed with descaling as indicated.
• Use only descaler supplied by De’Longhi. Using unsuitable
descaler and/or performing descaling incorrectly may re-
sult in faults not covered by the manufacturer’s guarantee.
• Before use, read the instructions and the labelling on the
descaler pack.
• Descaler can cause damage to delicate surfaces. If the prod-
uct is accidentally spilt, dry immediately.
