6.6 De-scaling
After the machine has been used for a while it must be de-scaled. This is particu-
larly important if you use hard water (over 10 ºDH). De-scaling removes any lime
scale deposits in the machine’s components and ensures that the machine contin-
ues to function correctly.
De-scalingisdoneasfollows:
Switch off the power to the machine. If
the machine is connected to a mains
watersupply then also shut off the
water.
Drain the machine’s water heater tank
(1,gure20)andthemanuallltank(2).
Note that the water from the heater tank
is very hot. Put back the clamps (3) on
the hoses when the tanks are empty
(gure20).
Mix 1.5 dl. Jede Cleaner with 3 litres cold
 water.Removethebluellcapmarked
“water”andpourthenishedmixtureinto
the manuallltank.(gure21).
Start the machine and check that it func-
tions normally, the red LED will extinguish
after approx. 5 minutes, the green LED
