Why Kärcher K 240 output pressure varies high and low?
- Ttiffany32Aug 17, 2025
If the output pressure of your Kärcher Pressure Washer is fluctuating, it could be due to: * Insufficient inlet water supply. Turn the water on full force and check the garden hose for kinks, leaks, or blockages. * The pump sucking air. Ensure 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 out 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.
