Why doesn't my Kärcher K 2.150 reach high pressure?
- D
  Dr. Jessica HardingAug 15, 2025
  If your pressure washer isn't reaching high pressure, it might be due to a few reasons. Ensure the diameter of the garden hose is adequate; replace it with a 16 mm (5/8 inch) or larger hose if it's too small. Check for any restrictions in the water supply, such as kinks, leaks, or blockages in the garden hose. Make sure there is enough inlet water supply by opening the water source fully. A clogged water inlet filter can also be the cause; remove it and rinse it in warm water. Lastly, verify that the spray wand is set to the high pressure position.

Why won't my Kärcher K 2.150 motor start?
- P
  Peggy BrownAug 18, 2025
  The motor may not start because the On/Off switch is in the OFF position. Ensure the switch is in the ON position. Also, check if the power cord is properly plugged in and that the electrical outlet supplies adequate power; try a different outlet if needed. A tripped GFCI plug can also prevent starting; press the RESET button on the GFCI plug. Finally, a tripped circuit breaker can be the reason. In this case, switch off the pressure washer and wait for it to reset automatically as the unit cools.

What to do if my Kärcher K 2.150 Pressure Washer has no detergent?
- K
  Kayla SmithAug 22, 2025
  If your pressure washer isn't dispensing detergent, start by checking the detergent siphon tube connection to ensure it's properly connected. If connected, the detergent might be too thick; dilute it, or use Kärcher detergent for best results. Also, check if the filter on the detergent siphon tube is clogged and rinse it with warm water to remove debris. A damaged or clogged detergent siphon tube may also be the culprit, so remove any obstruction or replace the tube. Finally, make sure the spray wand is in the low pressure position and that the discharge nozzle is not obstructed; clear any debris with a fine needle.

Why is the output pressure of my Kärcher K 2.150 Pressure Washer varying?
- U
  umilesAug 26, 2025
  If the output pressure is fluctuating, first ensure there's enough inlet water supply by turning the water on full force and checking the garden hose for kinks, leaks, or blockages. Also, the pump may be sucking air; verify that all hoses and fittings are airtight. Turn off the machine and purge the pump by squeezing the trigger gun until a steady water flow emerges through the nozzle. A clogged water inlet filter or obstructed discharge nozzle can also cause pressure variations; remove the filter and rinse in warm water, and blow out the nozzle or remove debris with a fine needle. Lastly, if the gun, hose, or spray wand are calcified, run distilled vinegar through the detergent suction tube.

- S

  A noisy pump often indicates that it's sucking air. Check that all hoses and fittings are airtight. Turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle.

What does it mean if my Kärcher K 2.150 Pressure Washer has water leaks from pump?
- G
  Grace RochaSep 7, 2025
  Water leaking from the pump (up to 10 drops per minute is permissible) could be due to loose fittings. Check that all fittings are tight. If the leaking persists, call Customer Support.
