What to do if the indicator lamp "Dry running" lights up on my Kärcher Switch?

If the indicator lamp "Dry running" lights up and the Kärcher Switch pump doesn't run or suddenly stops, it could be due to a lack of water in the pump's suction area. To resolve this, remove the air from the suction area following the operating instructions. Then, press the reset key to switch on the pump for 15 seconds. If one restart isn't enough, you can press reset again. Another cause might be a blocked suction area. In this case, pull out the mains plug and clean the suction area.
