What to do if my Kärcher K 240 Pressure Washer doesn't reach high pressure?
- AAlyssa ArnoldSep 13, 2025
If your Kärcher Pressure Washer isn't reaching high pressure, first, replace the garden hose with a 3/4 inch one if the current diameter is too small. Then, check the garden hose for any kinks, leaks, or blockages that may be restricting the water supply. Make sure that the water source is fully open to provide enough inlet water supply. Clean the water inlet filter by removing it and rinsing it in warm water. Finally, ensure that the soap nozzle is removed and the spray wand is properly connected.
