What to do if KingCraft Pressure Washer motor hums but fails to start?

If your KingCraft Pressure Washer motor hums but doesn't start, there might be several reasons. First, check the electrical connection, as the main voltage could be too low. Ensure the gun is activated by switching the machine ON and operating the gun. Also, the extension cord might be too small, so use an extension cord of sufficient size. You can find electrical requirements in the safety instructions.
