How to Start a Power Washer: A Beginner’s Step-by-Step Guide
Starting a power washer for the first time can seem daunting. But with the right guidance, you’ll be ready to tackle grimy driveways, dirty siding, and grungy decks in no time. This step-by-step guide is designed for absolute beginners to ensure a safe and effective start every time.
Pre-Start Checklist: Safety and Setup First
Before you even think about pulling the starter cord, proper preparation is crucial. Always consult your owner’s manual for model-specific instructions.
Gather Your Equipment and Fuel
You’ll need the power washer, a garden hose, a high-pressure spray wand, and the correct nozzle (typically a 25-degree white nozzle for general cleaning). For gas models, ensure you have fresh, unleaded gasoline and the recommended engine oil. Electric models simply need a grounded outdoor outlet and an extension cord rated for outdoor use.
Connect Water Supply and Wand
Attach your garden hose to the water inlet on the machine. Turn on the water source fully and let it run for 30 seconds to purge air from the hose. Then, connect the high-pressure spray wand to the pump outlet. Important: Never start the pump without water flowing through it, as this can cause severe damage.
The Step-by-Step Starting Procedure
Follow these steps in order for a smooth start. The process differs slightly between gas and electric models.
For Gas-Powered Pressure Washers
1. Move the fuel valve to the “On” position.
2. Set the choke to “Full” if the engine is cold.
3. Turn the engine switch to “On.”
4. Firmly grip the spray gun trigger to engage the water flow.
5. Pull the starter cord steadily and firmly until the engine starts. Once running, move the choke to “Half” and then to “Off” as the engine warms.
For Electric Pressure Washers
Starting an electric unit is simpler. Ensure the unit is plugged into a GFCI outlet. Squeeze and hold the trigger on the spray gun to release pressure in the pump, then press the power button or switch. The machine should start immediately.

Common Beginner Mistakes and Troubleshooting
If your power washer won’t start, don’t panic. Here are quick fixes for common issues:
Engine Won’t Turn Over (Gas): Check the fuel level, ensure the fuel valve is on, and confirm the engine switch is in the “On” position. An old spark plug is also a frequent culprit.
No Pressure (Electric/Gas): You likely forgot to squeeze the trigger before starting. Turn the machine off, squeeze the trigger to release pressure, and restart. Also, verify your water tap is fully on.
Machine Surges or Sputters: This often indicates air in the pump. Check all hose connections for leaks and ensure the water supply is uninterrupted.
