Care and service

Descaling the steam boiler 

Note

Since the lime clogs the appliance, we recommend des-
caling the appliance based on the number of times the 
water reservoir is filled as specified in the table (TF=tank 
fillings).

Note

Your water board or municipal utilities authority can pro-
vide information on hardness of tap water.

ATTENTION

Damaged surfaces

The descaler may corrode sensitive surfaces.
Fill and empty the appliance carefully. 

1. Switching off the device, see chapter 

 Switching off 

the device

.

2. Allow the device to cool down.
3. Drain the water reservoir.
4. Remove the accessory/accessories from the acces-

sory holders.

5. Open the maintenance lock. To do this place the 

open end of an extension tube on the maintenance 
lock, insert this into the guide so it engages and 
open it.

ATTENTION

Appliance damage due to descaler

An unsuitable descaler or incorrect dosing of the descal-
er may damage the appliance.
Only use KÄRCHER descaler.
Use 1 dosing unit of the descaler for 0.5 l water.

7. Apply descaler solution to the descaler according to

the details.

8. Fill the descaler solution into the steam boiler. Do 

not seal the steam boiler.

9. Allow the descaler solution to take effect for 

approx. 8 hours.

10. Drain descaler solution completely out of the steam 

boiler.

11. Repeat the descaling process if necessary.
12. Rinse the steam boiler 2-3 times with cold water in

order to drain all the descaler solution residue.

13. Drain the water completely out of the steam boiler.
14. Dry the mounting for the grid connection cable.
15. Close the maintenance lock with an extension tube.

Care of accessories

(Accessories - depending on scope of delivery)

Note

The micro fibre cloths are not suitable for dryer.

Note

When washing the cloths, observe the instructions on 
the washing tag. Do not use any liquid softeners as this 
will affect the ability of the cloths to pick up dirt.

1. Wash the floor cleaning cloths and covers at a max. 

temperature of 60 °C in the washing machine.

Troubleshooting guide

Malfunctions often have simple causes that you can 
remedy yourself using the following overview. When in 
doubt, or in the case of malfunctions not mentioned 
here, please contact your authorised Customer Service.

WARNING

Risk of electric shock and burns

Trying to eliminate faults while the appliance is connect-
ed to the mains or has not yet cooled down is always 
dangerous. 
Remove the mains plug.
Allow the appliance to cool down.

The water shortage indicator light flashes red and a 
signal tone sounds

No water in the tank.

Fill the water reservoir up to the “MAX” marking.

The water shortage indicator light is lit in red

No water in the steam boiler. The pump’s overheat pro-
tection has triggered.
1. Switch the device off; see Chapter 

 Switching off the 

device

.

2. Fill the water reservoir.
3. Switch on the device; see Chapter 

 Switching on the

The water tank is not inserted correctly or is calcified.
1. Remove the water reservoir.
2. Rinse the water reservoir.
3. Insert the water reservoir and press downwards until 

it locks into place.

The steam lever cannot be pressed

The steam lever is locked with the child lock.

Set the child lock (selector switch for steam volume) 
to the front.
The steam lever is released.

Long heating-up time

The steam boiler is scaled.

Descale the steam boiler.

High water output

The steam boiler is scaled.

Descale the steam boiler.

The steam pressure iron “spits” water

Rinse or descale the steam boiler of the steam 
cleaner; see Chapter

 Descaling the steam boiler

After ironing breaks, water droplets come out of the 
steam pressure iron

During longer ironing breaks, steam can condense in 
the steam line.

After pauses in the ironing process, direct the blast 
of steam onto a cloth until the steam flows evenly.
