Safety Devices

Caution
Safety devices protect the user
and must not be modified or by-
passed.

Pressure controller

The pressure controller keeps the boil-
er 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 boil-
er and is reactivated in case of a pres-
sure drop in the boiler due to steam
tapping.

Boiler thermostat

If, in case of a malfunction, there is no
water in the boiler, the temperature in
the boiler rises. The boiler thermostat
turns off the heating. Once the boiler is
filled, normal operation can continue.

Safety thermostat

The safety thermostat turns off the ap-
pliance if the boiler thermostat and the
pressure controller fails and the appli-
ance overheats in case of a malfunc-
tion. Please contact your local
KÄRCHER customer service to ar-
range for the reset of the safety ther-
mostat.
Maintenance lock
The maintenance lock acts as a pres-
sure control valve at the same time. It
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,
the pressure control valve, and steam
is emitted through the maintenance
lock to the outside.
Please contact your local KÄRCHER
customer service before you put the
appliance into operation again.
