How to fix a Stihl RE 120 that hums but doesn't start?

  Faith GalvanSep 9, 2025
  If your Stihl Pressure Washer does not start and the electric motor hums, it could be due to a few reasons. One possibility is that the mains voltage is too low. To address this, squeeze and hold the spray gun trigger while switching on the pressure washer, and switch off other loads connected to the same circuit. Additionally, ensure that you are using an extension cord with an adequate cross-section and correct length.
