Why does the pressure fluctuate or drop on my Stihl RE 163 Pressure Washer?
- K
  Kevin MichaelAug 1, 2025
  Pressure fluctuations or drops in your Stihl Pressure Washer can occur due to several reasons. It could be due to a shortage of water, so ensure the water tap is fully open and that you comply with the permissible suction lift if using suction mode. A dirty high-pressure nozzle in the spray head or a clogged water intake strainer in the pump inflow can also cause this issue; clean them accordingly. Alternatively, the high-pressure pump might be leaky, the valves may be defective or the nozzle could be clogged, in these cases you should clean the nozzle.

How to troubleshoot a Stihl RE 163 Pressure Washer motor that hums but doesn't run?
- N
  Natalie Stevens MDAug 6, 2025
  If your Stihl Pressure Washer motor hums but doesn't run, several factors could be responsible. First, the mains voltage might be too low or improper, so check the electrical connection, plug, cable, and switch. An extension cord with the wrong cross-section or one that's too long can also cause this; use an extension cord with a sufficient cross-section or connect the machine without one, or use a shorter one. Also, the mains circuit-breaker may have been tripped; in this case, switch off the machine, actuate the spray gun until water only drips out, engage the safety catch, and reset the mains circuit-breaker. Finally, make sure to actuate the spray gun when switching on the machine.

  If your Stihl Pressure Washer is not dispensing detergent, there are a few possible reasons. First, check if the detergent tank is empty and fill it if necessary. Also, the detergent intake might be clogged, so try to eliminate the clog. If these steps don't work, the venturi nozzle may be worn.
