If the phase failure protection or winding protection switch has been triggered on your Kärcher Pressure Washer, remove the cause of the problem and turn on the appliance again.
Why is my Kärcher Pressure Washer not building up pressure?
If your Kärcher Pressure Washer isn't building up pressure, several factors could be the cause. Try these steps: First, check and increase the water input amount. Next, inspect, clean, or replace the water fine filter. After that, check or replace the high-pressure nozzle. Finally, check or replace the pressure and suction valves and check, adjust, or replace overflow valve.
What to do if Kärcher HD 9/50-4 Cage Pressure Washer continuously turns on and off?
If your Kärcher Pressure Washer cycles on and off while the hand spray gun is closed, try these steps: Check the hand spray gun for leaks and replace it if necessary. Inspect the O-rings on the high-pressure hose for leaks, replacing them if needed. Check the pressure holding valve for leaks, replacing the O-rings. Also, check, adjust, or replace the overflow valve. Finally, check or replace the pressure switch and control piston and check or replace electronics.
What to do if my Kärcher HD 9/50-4 Cage unit does not work?
If your Kärcher Pressure Washer isn't working, begin by checking or replacing the supply voltage, connecting cables, and power fuse. Also, check the fuse (F1). Check the appliance switch for continuity, and replace it if needed. Inspect the pressure switch and replace it if required. Check the control transformer and replace the fuse. Check or replace the temperature fuse. Check or replace the control board and soft start. Finally, check or replace the contactor (K1).
