8. Safety elements

This steam cleaner is equipped with several
safety devices that provide an all-round
protection of the appliance. The most important
safety devices are described in the following.

Pressure controller

The pressure controller keeps the boiler
pressure during the operation as constant as
possible. The heating is turned off if the
maximum operating pressure of 4 bar is reached
in the boiler and is reactivated in case of a
pressure drop in the boiler due to steam tapping.

Low-water thermostat

When the water in the boiler becomes
exhausted, the temperature of the heating
increases. The low-water thermostat turns off
the heating, and the red low-water indicator
lamp (B6) lights up. The heating is prevented
from being turned on again until the boiler has
cooled down or refilled with water.

Safety thermostat

If the low-water thermostat fails and the
appliance overheats, the safety thermostat turns
off the steam cleaner. Please contact your local
Kärcher customer service to arrange for the
reset of the safety thermostat.

Safety lock

The safety lock seals the boiler against the steam
pressure that builds up in the boiler. If the
pressure controller is defect and the steam
pressure in the boiler rises above 5.7 bar, a
pressure control valve in the safety lock opens,
and steam is emitted through the lock to the
outside. Please contact your local Kärcher
customer service before you put the appliance
into operation again.
Excess temperature protection on
the power cord holder
If the power cord is not completely uncoiled from
the power cord holder during the operation of
the appliance, it may heat up excessively. The
appliance is equipped with an excess
temperature protection to prevent an excess
heating.
