Why does the output pressure of my Kärcher K 2.360 vary?

If the output pressure of your Kärcher Pressure Washer varies, it could be due to several reasons. Ensure you have enough inlet water supply by turning the water on full force and checking the garden hose for kinks, leaks, or blockages. The pump might be sucking air; check that all hoses and fittings are airtight and purge the pump by turning off the machine and squeezing the trigger gun until a steady flow of water emerges. Also, inspect the water inlet filter for clogs and rinse it in warm water. Finally, the discharge nozzle could be obstructed, so blow out or remove any debris with a fine needle. If the gun, hose, or spray wand is calcified, run distilled vinegar through the detergent suction tube.
