Pressure Washer Troubleshooting

Issue

Possible Cause

Solution

When trying to start the pressure washer, the engine is not turning over.

Not getting gas

Check to see if the motor has gas. This is either on top of the motor on in a separate tank.

Ground or power connection

Some motors need to be hooked to external ground and power supplies. Check these connections on the power source (typically a battery) and at the pressure washer. Vibration and chemicals can cause these connections to loosen or rust. 

Fuel lines or Fuel Filter

If your engine is not getting fuel it will not start. Review the fuel filters and fuel lines to ensure they are intact and in good working order.

Spark Plugs

Check the spark plug. Recall the last time it was replaced. If it has been over 1 year, it might be time to replace it
