Why does my Stihl Pressure Washer pressure fluctuate or drop?
- T
  Thomas JordanAug 8, 2025
  If the pressure fluctuates or drops in your Stihl Pressure Washer, it could be due to several reasons. First, ensure that the water supply is sufficient by completely opening the water tap and complying with the permissible suction lift if you are using suction mode. Check and clean the high-pressure nozzle in the spray head, the water intake strainer in the pump inflow, or the nozzle, as they might be dirty or clogged. If the issue persists, the high-pressure pump may be leaky, or the valves may be defective.

How to fix a Stihl Pressure Washer motor that hums but doesn't run?
- Q

  If your Stihl Pressure Washer's motor hums but doesn't run when switched on, it could be due to several reasons. Ensure the mains voltage is adequate and the electrical connections, plug, cable, and switch are in good condition. If you're using an extension cord, make sure it has a sufficient cross-section and isn't too long. Also, check if the mains circuit-breaker has been tripped—if so, switch off the machine, actuate the spray gun until water only drips out, engage the safety catch, and then reset the circuit-breaker. Finally, make sure to actuate the spray gun when switching on the machine.
