Why does my Kärcher Pressure Washer pressure go up and down?
- D
  Danny CraigAug 14, 2025
  If the output pressure of your Kärcher Pressure Washer varies, first, ensure you're providing enough inlet water by turning the water on full force and checking the garden hose for kinks, leaks, or blockages. Next, check if the pump is sucking air by making sure all 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. Also, inspect the water inlet filter for clogs and rinse it in warm water. Lastly, check the discharge nozzle for obstructions, and blow out or remove debris with a fine needle. If the gun, hose, or spray wand are calcified, run distilled vinegar through the detergent suction tube.

  If your Kärcher Pressure Washer isn't reaching high pressure, first, replace the garden hose with a 5/8 inch or larger one. Then, check the garden hose for any kinks, leaks, or blockages that may be restricting the water supply. Ensure you open the water source full force to provide enough inlet water. Clean the water inlet filter by removing it and rinsing it in warm water. Lastly, check that the spray wand is turned to the high-pressure position.

  If your Kärcher Pressure Washer's motor won't start, first ensure the On/Off switch is in the “ON” (I) position. Then, check the GFCI plug and press the “RESET” button. Verify the power cord is securely plugged in. If it still doesn't work, try a different electrical outlet to rule out inadequate power supply.

Why is my Kärcher Pressure Washer not using detergent?

  wcardenasAug 25, 2025
  If your Kärcher Pressure Washer isn't dispensing detergent, start by checking that the detergent suction tube is properly connected to the machine. If it is, the detergent might be too thick; dilute it, or ideally, use Kärcher detergent. Also, inspect the filter on the detergent suction tube for clogs and rinse it with warm water to remove any debris. If the suction tube is damaged or clogged, remove the obstruction or replace the tube. Ensure the spray wand is in the low-pressure position. Lastly, check the discharge nozzle for obstructions and blow out any debris with a fine needle.
