Decalcification
Risk of damage in frost conditions.
In frost conditions, ambient temperatures be-
low 39 °F (4 °C), there is a risk that water in
pipes, faucets and appliances could freeze.
This can cause considerable damage.
• Do not decalcify the appliance in frost con-
ditions.
Decalcification frequency
Lime scale occurs especially as a result of
precipitation from “hard” water. The appliance
must be decalcified regularly depending on wa-
ter hardness and hot water consumption.

Decalcification (models with
control panel)
AquaGo comfort / AquaGo comfort plus
with control panel (included with delivery).
An integrated water consumption meter rec-
ognizes (after hot water consumption of ap-
prox. 1585 gallons / 6000 l) that decalcification
is necessary. The assumed water hardness is
“hard” and cannot be changed. The yellow
status LED 3 (Fig. 9) indicates that decalcifica-
tion is necessary (goes off briefly about every
7 seconds).
