Why does my Kärcher K 2.56 M Pressure Washer have inconsistent pressure?
- TtanyawardSep 10, 2025
If the output pressure of your Kärcher Pressure Washer is fluctuating, ensure that the water is turned on full force and check the garden hose for kinks, leaks, or blockages. Inspect hoses and fittings to ensure they are airtight. If the pump is sucking air, turn off the machine and purge the pump by squeezing the trigger gun until a steady water flow emerges. Also, check if the water inlet filter is clogged and clean it. Clear any obstructions from the discharge nozzle and run distilled vinegar through the detergent suction tube if the gun, hose, or spray wand is calcified.
