What to do if my Kärcher Pressure Washer is not dispensing detergent?
- T
  Travis SandovalAug 5, 2025
  If your Kärcher Pressure Washer isn't dispensing detergent, several issues could be the cause. First, check that the detergent suction tube is properly connected to the machine. If the detergent is too thick, dilute it, and for best results, use Kärcher detergent. A clogged filter on the detergent suction tube can also be the problem; run warm water through it to remove debris. The detergent suction tube itself might be damaged or clogged; remove any obstruction or replace the tube. Ensure you have the correct nozzle attached; replace any high-pressure nozzle with the black detergent nozzle. Lastly, the spray nozzle could be obstructed; blow out any debris with a fine needle.

Why is water leaking from the pump of my Kärcher G 3050 OHC Pressure Washer?
- A
  Alex JohnsonAug 26, 2025
  A small amount of water leaking from the pump (up to 10 drops per minute) is permissible. However, if the leakage is excessive, check the fittings to ensure they are tight. Also, the thermal protection device may be activated; this will auto reset, but avoid running the pump for more than 5 minutes without spraying.

  Several factors can prevent your Kärcher Pressure Washer from reaching high pressure. The garden hose might be too small; replace it with a 5/8 inch or larger hose. The water supply could be restricted due to kinks, leaks, or blockages in the hose. Ensure you have enough inlet water supply by turning the water on full force and checking the hose. Also, the water inlet filter could be clogged; remove it and rinse it in warm water. Make sure you're using the correct nozzle; remove the black detergent nozzle and attach the high-pressure nozzle. If the pump is sucking air, check that hoses and fittings are airtight and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle.
