Maintenance and care

Danger
Always disconnect the mains plug and al-
low the steam cleaner to cool down before
performing any maintenance work.
Rinsing the boiler
Rinse the boiler of the steam cleaner boiler
at the latest after 5 boiler fillings.
 Fill the boiler with water and shake it
strongly. This dissolves lime scaling re-
siding on the boiler bottom.
 Empty water out.
Descaling the boiler
Note
If you always use usual commercial distilled
water it is not necessary to descale the boil-
er.
As limescale also builds up on the boiler
walls, we recommend to descale the boiler
using KÄRCHER Bio descaler RM 511.
The KÄRCHER Bio descaler RM 511 is a
product based on citric acid, which is com-
pletely biodegradeable.
Caution
Only use products approved by KÄRCHER
to exclude any damages of the appliance.
 Disconnect the mains plug from the
socket.
 Completely empty the steam boiler.
 Completely dissolve two bags of
descaler by stirring it in 2 liters of warm
water.
 Fill the descaling solution into the boiler
and allow to react for approximately 8
hours.

Danger
Do not screw the steam boiler safety cap on
the appliance during the descaling. Do not
use the appliance as long as there is des-
caling agent in the boiler.
 Pour out the descaling solution. Rinse
the boiler at least two more times with
cold water to ensure that there is no res-
idue left behind in the boiler.
 Turn on the appliance.
 Press the reset key until the indicator
lamp "Descaling" goes off.
The appliance is ready for use again. After
approx. 50 operating hours, the indicator
lamp "Descaling" shows the next neces-
sary descaling process.
Filter replacement
Using soiled water can occlude the filter. This
is shown by extraordinaly long run times of
the pump or a complete malfunction.
 Replac the filter.
