  If your Kärcher Pressure Washer cycles on and off with the hand spray gun closed, it could indicate a system tightness or pressure issue. Begin by checking the trigger gun and O-rings on the high-pressure hose for leaks, replacing them if necessary. Also, check, adjust, or replace the overflow valve, and inspect or replace the pressure retaining valve and pressure switch. Finally, check, clean, or replace the detergent check valve, and examine the pressure and suction valves for any leaks, replacing as needed.

Why is my Kärcher Pressure Washer not building up pressure?
- D
  David TranAug 16, 2025
  Several factors can prevent your Kärcher Pressure Washer from building pressure. Start by setting the nozzle to "High pressure" and cleaning or replacing it if soiled. If that doesn't work, vent the appliance to remove any air within the system. Ensure you have sufficient water supply, checking against the technical data. Also, clean the sieve in the water connection and inspect all inlet pipes to the pump for blockages. Lastly, check the pressure and suction valves for leaks and the overflow valve for proper adjustment or replacement.

  If your Kärcher Pressure Washer isn't sucking in detergent, the issue likely lies within the detergent flow. First, check and clean the detergent suction hose and filter. Then, open or check and clean the detergent dosing valve. Also, inspect, clean, or replace the detergent check valve, and check or replace the nozzle for detergent. As a last resort, replace the detergent injector.

  If your Kärcher Pressure Washer pump is leaking, determine the source of the leak. If water is leaking between the cylinder head and piston casing, check and replace the high and low-pressure seals. If oil is leaking from the same area, replace the oil seals.
