Why does the output pressure of my Kärcher Pressure Washer vary?
- HHayley BrownAug 19, 2025
If the output pressure of your Kärcher Pressure Washer varies, ensure that the water is turned on full force and check the garden hose for kinks, leaks, or blockages. Verify that the hoses and fittings are airtight to prevent the pump from sucking air; if necessary, turn off the machine and purge the pump by squeezing the trigger gun until a steady water flow emerges. Also, clean the water inlet filter by removing and rinsing it in warm water. Clear any obstruction from the discharge nozzle using a fine needle, and if there's calcification, run distilled vinegar through the detergent suction tube.
