Why Kärcher Pressure Washer unit does not reach high pressure?
- TTiffany DiazAug 20, 2025
If your Kärcher Pressure Washer isn't reaching high pressure, it could be due to several reasons: 1. The diameter of your garden hose might be too small; replace it with a 5/8 inch or larger hose. 2. Your water supply could be restricted; check the garden hose for kinks, leaks, or blockages. 3. There might not be enough inlet water supply; turn the water on full force and inspect the hose for issues. 4. The water inlet filter could be clogged; remove the filter and rinse it in warm water. 5. The black detergent nozzle might be attached; remove it and attach a high-pressure nozzle.
