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, a pres-
sure control valve in the safety lock opens, 
and steam is emitted through the lock to the 
outside. 
Please contact your local KÄRCHER cus-
tomer service before you put the appliance 
into operation again.
