What to do if my Kärcher Pressure Washer unit does not reach high pressure?
- EErin WilliamsJul 30, 2025
If your Kärcher Pressure Washer isn't reaching high pressure, several factors could be the cause. First, the diameter of your garden hose might be too small; replace it with a 3/4 inch garden hose. Second, the water supply could be restricted; check the garden hose for kinks, leaks, or blockages. Third, there might not be enough inlet water supply; open the water source fully. Fourth, the water inlet filter could be clogged; remove it and rinse it out in warm water. Lastly, the spray wand might be in the low-pressure position; turn the spray wand tip to the high-pressure position.
