  If your Kärcher Pressure Washer isn't reaching high pressure, check these potential causes: * Ensure you're using a garden hose with a diameter of 5/8 inch or larger. * Check the garden hose for any kinks, leaks, or blockages that might be restricting the water supply. * Make sure the water is turned on full force and that there are no obstructions in the hose. * Inspect the water inlet filter for clogs and rinse it out in warm water if needed. * Verify that the high-pressure nozzle is attached instead of the black detergent nozzle.

Why Kärcher Pressure Washer leaks water from pump?

  Water leaking from the pump of your Kärcher Pressure Washer is permissible up to 10 drops per minute. If the leakage is more, try tightening the fittings. If the issue continues, it may be due to damaged or worn water seals, in which case you should contact Customer Support. It could also be due to the thermal protection device being activated; this will auto-reset, but avoid running the pump for more than 5 minutes without spraying.

  If your Kärcher Pressure Washer spray wand is leaking, make sure it's properly attached by turning the swivel nut of the gun clockwise until the connection is tight. If the issue persists, it could be due to a broken o-ring or plastic insert, in which case you should contact Customer Support.

  If your Kärcher Pressure Washer pump is making unusual noises, it might be sucking in air. Check all hoses and fittings to ensure they are airtight. Then, turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water comes out of the nozzle.

  If you're not getting any detergent from your Kärcher Pressure Washer, start by checking the detergent suction tube to ensure it's properly connected. If the detergent is too thick, dilute it, preferably using Kärcher detergent. Also, check the filter on the detergent suction tube for clogs and rinse it with warm water. If the detergent suction tube is damaged or clogged, remove the obstruction or replace the tube. Ensure that the black detergent nozzle is attached instead of a high-pressure nozzle. Finally, clear any obstructions from the spray nozzle.

Why does Kärcher Pressure Washer output pressure vary?
- D
  Dr. Cynthia LucasSep 5, 2025
  If the output pressure of your Kärcher Pressure Washer varies, consider the following: * Ensure there is enough inlet water supply by turning the water on full force and checking the garden hose for kinks, leaks, or blockages. * Check that all hoses and fittings are airtight to prevent the pump from sucking air. If it is, turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. * Also, inspect the water inlet filter for clogs and rinse it out in warm water if necessary. * Clear any obstructions from the spray nozzle by blowing it out or removing debris with a fine needle. * If the gun, hose, or spray wand is calcified, run distilled vinegar through the detergent suction tube.

  If your Kärcher Pressure Washer isn't reaching high pressure, first, check that you are using a 5/8 inch or larger garden hose. Next, make sure the water supply isn't restricted by kinks, leaks, or blockages in the hose. Ensure you have enough inlet water supply by turning the water on full force and again checking for any obstructions. Also, inspect the water inlet filter for clogs and rinse it out in warm water if needed. Finally, make sure you have attached a high pressure nozzle instead of the black detergent nozzle.
