If the drain hose for dirty water is blocked on your Kärcher Scrubber: * Open the dosing equipment at the drain hose. * Pull out the suction hose from the suction beam and close it by hand. * Set the program selection switch to suction or vacuuming, which will suck the blockage out of the drain hose and into the dirt water tank.
