Descaling Procedure - Philips HD7854 User Manual

8 Descaling
8.0.1 When to descale
•
Descale the SENSEO
described below when the CALC CLEAN
indicator goes on. The CALC CLEAN
indicator goes on after you have brewed
approx. 1000 cups of SENSEO
or 250 cups of SENSEO
milk. You can also descale the SENSEO
machine more often in the same way. You
have to descale the machine at least every
3 months. The descaling procedure takes
approx. 45 minutes (Fig. 45).
8.0.2 Why to descale
Scale builds up inside the machine during use. It is
essential to descale the SENSEO
when the CALC CLEAN indicator goes on. Your
reasons to descale:
•
It prolongs the life of your SENSEO
machine
•
It ensures maximum cup volume
•
It ensures maximum coffee temperature
•
The machine produces less sound during
brewing
• It prevents malfunctioning
If the descaling procedure is not performed
correctly, scale residues remain behind in the
machine. This causes scale to build up more
quickly and may cause permanent and irreparable
damage to the machine.
8.0.3 Use the correct descaling agent
Only citric acid-based descalers are suitable for
descaling the SENSEO
descaler descales the machine without damaging
it. For the correct amount, see section 'Descaling
procedure' below. Each descaling mixture can be
used only once. After use, the descaling mixture is
no longer active.
Philips SENSEO
has developed a special descaler

(HD7012, HD7011, HD7006) for SENSEO
machines. For more information about this
