If your spark plug is dirty, cracked, or defective, it could be the reason your power washer won’t start. Your power washer’s spark plug is essential to keep it running since it ignites the air/fuel mixture. After the old fuel has been drained and cleaned, you can fill the tank with fresh gasoline and turn the fuel valve to “on” or “open.”Ī defective spark plug or ignition coil may need to be replaced. If you haven’t used the power washer in a while, it’s important to clean and flush the pressure washer’s fuel tank with carburetor cleaner. In some cases, a pressure washer may be able to start with old fuel, but the pressure washer won’t stay running. This means that the gas will lose octane and volatility, resulting in a lack of combustion and an inability to start. Fuel that’s been sitting in your gas pressure washer for 6 months or more can oxidize and become contaminated. If your gas-powered Generac, DeWalt, or Craftsman power washer won’t start, it could be because of old fuel. Stale fuel that’s been sitting in a gas pressure washer may need to be cleaned out. If the amperage is below the required amperage for your motor, you’ll either need to call an electrician to perform some panel enhancements or get a pressure washer that needs less power.
