What to do if the motor does not start on my Nilfisk-Advance MC 7P Pressure Washer?

  Matthew GibsonJul 25, 2025
  If the motor of your Nilfisk-Advance Pressure Washer doesn't start, first ensure the plug is correctly inserted and there is power. If there is still no power, have a skilled electrician check the plug, lead, and switch, replacing them if necessary. Also, check the oil level and add oil if it's too low. Verify that the mains fuse is switched on. Finally, overheating or overloading may have activated the overload protection; in this case, ensure the mains voltage and cleaner voltage are the same, switch off the cleaner, and allow it to cool for at least 3 minutes.

  If the motor on your Nilfisk-Advance Pressure Washer switches off, it could be due to overload protection being activated from overheating or overloading. Check that the mains voltage and the cleaner voltage are the same. Switch off the cleaner and allow it to cool for at least 3 minutes. Another potential cause is a dirty high-pressure nozzle, which would require replacement.

Why does my Nilfisk-Advance Pressure Washer motor buzz but not start?
- D
  Deborah JamesAug 4, 2025
  If your Nilfisk-Advance Pressure Washer motor buzzes without starting, the mains voltage may be too low, or there could be a phase failure; have the electrical connection checked. Alternatively, the pump might be blocked or frozen; contact Nilfisk customer service for assistance. Lastly, an incorrect cross-section or length of the extension lead could be the cause; use a lead with the correct specifications.

Why is there a pressure drop in my Nilfisk-Advance MC 7P Pressure Washer?
- M
  Michelle PerezAug 9, 2025
  A pressure drop in your Nilfisk-Advance Pressure Washer can occur due to several reasons. It might be caused by air in the system. Try venting the system by operating the spray gun several times at short intervals; if needed, operate the cleaner briefly without the high-pressure hose. Another cause could be a blocked or worn high-pressure nozzle, which would require cleaning or replacement. Also, check if the detergent tank is empty and needs to be topped up, or ensure the detergent setting is not active if not needed.

Why is the pressure fluctuating on my Nilfisk-Advance Pressure Washer?

  Isabel ColeAug 14, 2025
  Pressure fluctuations in your Nilfisk-Advance Pressure Washer can stem from a few issues. If you are using suction mode, ensure the suction set is airtight to prevent the pump from drawing in air. Make sure the water tap is fully open and that the water inlet hose is adequate for the machine's water flow requirements. A blocked water filter could also be the culprit, so clean it (never operate the washer without a water filter). Finally, ensure you're adhering to the maximum permissible suction height as outlined in the instructions.

How to fix no detergent being drawn into my Nilfisk-Advance MC 7P Pressure Washer?
- W
  Wayne AvilaAug 20, 2025
  If your Nilfisk-Advance Pressure Washer isn't drawing in detergent, first check if the detergent tank is empty and top it up if needed. Ensure the cap on the FlexoPower-Plus nozzle head is set to low pressure. If you're using a double lance, make sure it's adjusted to low pressure as well. Lastly, the injector might be dirty, or the suction hose could be blocked; in this case, clean the affected components.
