    Why does my Stihl Pressure Washer engine keep stopping?
    • A
      Adam WolfAug 17, 2025
      If the engine of your Stihl Pressure Washer stops, the machine might be switching off because the motor is overheating. To resolve this, check whether the supply voltage and machine voltage match. Allow the motor to cool down for at least 5 minutes.

    How to troubleshoot a Stihl Pressure Washer when the motor hums but doesn't run?
    • R
      robert59Aug 19, 2025
      If the motor of your Stihl Pressure Washer does not run but hums when switched on, it could be due to several reasons. First, check the electrical connection, plug, cable, and switch, as the mains voltage might be too low or improper. If you're using an extension cord, ensure it has a sufficient cross-section. Avoid overly long extension cords; try connecting the machine directly or with a shorter cord. Also, the mains circuit-breaker might have tripped. In this case, switch off the machine, actuate the spray gun until water only drips out, engage the safety catch, and reset the breaker. Finally, make sure to actuate the spray gun when switching on the machine.

    Why does the pressure fluctuate or drop on my Stihl RE 98?
    • A
      aaronmcneilAug 30, 2025
      If you notice the pressure from your Stihl Pressure Washer fluctuating or dropping, several factors could be responsible. Ensure that the water supply is adequate by fully opening the water tap and complying with the permissible suction lift, especially in suction mode. Inspect the high-pressure nozzle in the spray head for dirt and clean it if necessary. Also, check the water intake strainer in the pump inflow for clogs and clean it. If the high-pressure pump is leaky or the valves are defective, have the machine checked by a servicing dealer.

      dhurstSep 5, 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 RE 98 Pressure Washer motor that hums but doesn't run?
    • M
      Melissa DeanSep 7, 2025
      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.
