    Why won't my Gerni Pressure Washer start?

      If your Gerni Pressure Washer refuses to start, there are several possible reasons. First, ensure the machine is properly plugged into a working socket. Try a different socket to rule out a defective one. Also, check the fuse and replace it if it has blown. Finally, a defective extension cable could be the culprit; try using the pressure washer without it.

      If your Gerni Pressure Washer suddenly stops, here's what to check: * Replace the fuse if it has blown. * Ensure the mains voltage corresponds to the specification on the model tag. * If the thermal sensor activated, leave the washer for 5 minutes to cool down. * Clean the nozzle, as a partially blocked nozzle can cause the machine to stop.

      If the fuse blows on your Gerni Pressure Washer, it might be too small. Change to an installation higher than the amp consumption of the machine. You may also try without the extension cable.

    How to fix fluctuating pressure on my Gerni Classic 100.3?

      Austin ReevesAug 29, 2025
      Fluctuating pressure in your Gerni Pressure Washer can be due to several reasons. Check that all hoses and connections are airtight to prevent the pump from sucking air. For dirty, worn out, or stuck valves, contact your local Gerni Service center. If the pump seals are worn out, clean and replace them or refer to a local Gerni distributor.

    Why is my Gerni Classic 100.3 pulsating?
    • J
      Jeffrey WhiteSep 4, 2025
      If your Gerni Pressure Washer is pulsating, it could be due to air in the inlet hose or pump. Allow the machine to run with the trigger open until regular working pressure resumes. Another cause could be an inadequate supply of mains water. Check that the water supply corresponds to the required specifications (see the model tag), and avoid using long, thin hoses (min. 1/2').
