Why is my Kärcher K 3.540 Pressure Washer pump leaking water?
If your Kärcher Pressure Washer pump is leaking water (more than 10 drops per minute), ensure that all fittings are tight. If the leaking continues, it may indicate that the water seals are damaged or worn.
What to do if my Kärcher Pressure Washer has no detergent?
If your Kärcher Pressure Washer isn't dispensing detergent, start by checking the detergent suction tube connection to ensure it's properly connected to the machine. If the detergent is too thick, dilute it—using Kärcher® detergent is recommended for best results. Also, inspect the filter on the detergent suction tube for clogs and rinse with warm water to remove any debris. If the detergent suction tube is damaged or clogged, remove the obstruction or replace the tube. Lastly, make sure the spray wand is in the low pressure position and the discharge nozzle is not obstructed; if obstructed, blow out or remove debris with a fine needle.

Why is my Kärcher Pressure Washer pump noisy?
