What to do if my Kärcher Pressure Washer doesn't reach high pressure?
- MMeghan BrownAug 8, 2025
If your Kärcher Pressure Washer isn't reaching high pressure, there could be a few reasons. First, the diameter of your garden hose may be too small; replace it with a 16mm diameter hose or larger. Second, your water supply might be restricted; check the garden hose for kinks, leaks, and blockages. Also, make sure you have enough inlet water supply by turning the water on full force and checking for any obstructions. The water inlet filter could also be clogged, so remove it and rinse it in warm water. Lastly, ensure that the black detergent nozzle is not attached; remove it and attach the high-pressure nozzle.
