Why does my Kärcher K 2.27 Pressure Washer have fluctuating pressure?
- DDavid TranAug 20, 2025
If the output pressure of your Kärcher Pressure Washer varies between high and low, it could be due to: * Insufficient inlet water supply. Ensure the water is turned on full force and check the garden hose for kinks, leaks, or blockages. * The pump sucking air. Check that hoses and fittings are airtight. Turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. * A clogged water inlet filter. Remove the filter and rinse it in warm water. * An obstructed discharge nozzle. Blow out or remove debris with a fine needle. * A calcified gun, hose, or spray wand. Run distilled vinegar through the detergent suction tube.
