Why is the pressure fluctuating on my Kärcher BG-282037?
- CChristopher DavidAug 25, 2025
If the pressure is fluctuating in your Kärcher Pressure Washer, it could be due to several reasons. The valves might be worn or blocked, in which case you should check and replace them if necessary. Another possibility is that the pump is sucking air; inspect the water supply and look for air seepage at joints in the suction line. Finally, check the piston packing for wear and replace it if needed.
