It is designed to connect to standard garden hoses. A G 3/4 inch connector is recommended for optimal performance, and ensure it has a water tap connection.

It should be stored in a dry, frost-free place. Ensure the unit is completely drained of water to prevent damage from freezing temperatures. Refer to the manual for specific winter storage instructions.

Check that the power cord is securely plugged into a working electrical outlet. Ensure the water supply is turned on and connected correctly. Check if the reset button on the power switch has been activated.

Verify that the water tap is fully open and the garden hose is not kinked. Clean the water inlet filter, as a clogged filter restricts water flow. Ensure the selected lance is correctly attached. Check for leaks in the hose connections.

The unit may have overheated. Turn off the pressure washer and allow it to cool down for at least 10-15 minutes before restarting. Ensure the air vents are not blocked.

Ensure the detergent tank is filled and the detergent suction tube is properly inserted and not blocked. Make sure you are using the correct detergent for Kärcher pressure washers. The detergent function typically only works at lower pressure settings.
