Why is my Kärcher G 2500 DC Pressure Washer not reaching high pressure?

If the Kärcher Pressure Washer unit does not reach high pressure, check if the diameter of the garden hose is too small (replace with a 5/8 inch or larger garden hose), the water supply is restricted (check garden hose for kinks, leaks, and blockage), there is not enough inlet water supply (turn water on full force and check the hose), the water inlet filter is clogged (remove filter and rinse in warm water), or the black detergent nozzle is attached (remove it and attach the high-pressure nozzle).
