Why does the output pressure of my Kärcher G 2600 VC Pressure Washer vary?
- DDeborah TuckerJul 29, 2025
If the output pressure of your Kärcher Pressure Washer varies, it could be due to several reasons. Make sure that the water is turned on full force and check the garden hose for kinks, leaks, or blockages. The pump might be sucking air; check that hoses and fittings are airtight, then turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. Another possibility is a clogged water inlet filter; remove it and rinse in warm water. The spray nozzle could also be obstructed; blow it out or remove debris with a fine needle. Finally, the gun, hose, or spray wand might be calcified; run distilled vinegar through the detergent suction tube.
