3. Care, Maintenance & Troubleshooting
3.1 Cleaning the boiler
Rinsing out the boiler
·
To clean the boiler, we recommend that you fill it
with water and shake it vigorously. This should
loosen any scale that has settled at the bottom of
the boiler. If you now pour the water out of the
boiler, the scale will be flushed out at the same
time (see ill.).
·
Rinse out the steam generator at most after every
5th fill-up if the hardness of water proves to be
more than 1.8 mmol/l. You can enquire about the
hardness of water in your area from your water
supply company or municipal public works.
Descaling the boiler
·
In order to remove any scale that has built up on
the walls of the boiler, we recommend that you
clean the boiler with KÄRCHER Biological
Decalcifying Liquid RM 511.
·
KÄRCHER Biological Decalcifying Liquid RM 511
is based on citric acid and is therefore entirely
biodegradable.
·
In order to avoid damaging your steam cleaner,
use only products for descaling that have been
officially approved by KÄRCHER.
Procedure:
·
As limescale is deposited in the steam generator,
we recommend descaling the tank at the
following intervals.
Remove lime-scale deposits after the given
number of tank fillings (TF).

·
Unplug the steam cleaner from the mains
electricity.
·
Empty the boiler entirely of any remaining water.
·
Dissolve the contents of one bag in 1 litre of warm
water while continuously stirring the liquid at the
same time.
·
Pour the solution into the boiler, and allow to
stand for approx. 8 hours.
The safety cap must not be attached to
the boiler while descaling is being
carried out. Make sure that the cleaner
can not be used while there is any
descaling solution left in the boiler.
·
Pour the contents of the boiler out at the side
(see ill.), and rinse out the boiler at least twice
with cold water to ensure that no descaling
solution or deposits are left inside.
·
The steam cleaner is now ready for use again.
3.2 Looking after the wiping cloths
·
The cloths have been pre-washed prior to supply.
They can be machine-washed at 60 °C, and then
tumble-dried. However, do not use any fabric
softeners.
3.3 What to do if there is a problem
·
If the low-water warning lamp (13) lights up
because the unit has been stood upright although
it still operating, follow the procedure described
in the section "Refilling the boiler with water".
·
If you encounter any other problems with the
cleaner, you should contact your local authorised
customer service agent.
