    What to do if my Gerni Super 140.3 stops?

      If your Gerni Pressure Washer stops, the fuse may have blown, so replace it. Also, the mains voltage might be incorrect; check that it corresponds to the specification on the model tag. The thermal sensor may have activated; if so, leave the washer for 5 minutes to cool down. Finally, the nozzle may be partially blocked; clean the nozzle (see section 7).

      If your Gerni Pressure Washer refuses to start, ensure it is properly plugged in. If it is, try another socket in case the current one is defective. Check the fuse and replace it if it has blown. Finally, if you are using an extension cable, try using the pressure washer without it, as the extension cable may be defective.

    Why does the fuse blow on my Gerni Super 140.3 Pressure Washer?

      The fuse blows because it is too small. Change to an installation higher than the amp consumption of the machine.

    Why does my Gerni Super 140.3 Pressure Washer have fluctuating pressure?
    • J
      Juan RobinsonAug 22, 2025
      If your Gerni Pressure Washer has fluctuating pressure, the pump might be sucking air. Check that hoses and connections are airtight. Alternatively, the valves could be dirty, worn out, or stuck, or the pump seals could be worn out. In these cases, clean and replace the defective parts or refer to your local Gerni distributor.

    What to do if my Gerni Pressure Washer starts, but no water comes out?

      Richard WeissAug 27, 2025
      If your Gerni Pressure Washer starts but no water comes out, the pump, hoses, or accessories might be frozen; wait for them to thaw. Ensure there is a water supply and connect the inlet water if it's missing. The water filter or nozzle could be blocked; clean the filter and the nozzle (see section 7).

    Why does my Gerni Super 140.3 Pressure Washer often start and stop by itself?

      Victor CastroAug 31, 2025
      If your Gerni Pressure Washer often starts and stops by itself, the pump or spray handle might be leaking. Contact your nearest Gerni Service Centre.
