Why does my Stihl RE 108 Pressure Washer pressure fluctuate or drop?
- SSarah WalkerJul 27, 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.
