# How to Start a Power Washer: A Step-by-Step Guide for Beginners
So, you’ve got a shiny new power washer and you’re ready to blast away grime! But before you unleash the high-pressure water, it’s crucial to know the correct startup procedure. This beginner-friendly guide will walk you through each step to ensure a safe and effective start every time.
## **Pre-Startup Safety & Preparation**
**Gather Your Essential Gear**
Before you even think about pulling the starter cord, safety comes first. Always wear protective eyewear and closed-toe shoes. Consider hearing protection for louder gas models and gloves for a better grip. Clear your work area of debris and ensure good ventilation if you’re using a gas-powered washer indoors (like a garage with the door open).
**Perform a Quick Machine Check**
Give your power washer a visual inspection. Check for any loose parts, cracks in the hoses, or visible leaks. Ensure the water inlet filter is clean. Connect your garden hose to the machine’s water inlet and turn on the water supply fully at the spigot. Let water run through the system for 30 seconds to purge any air from the pump—this is a critical step to prevent pump damage.
## **The Step-by-Step Starting Procedure**
**For Gas-Powered Pressure Washers**
1. **Check the Oil & Fuel:** Ensure the engine oil is at the correct level and you have fresh gasoline.
2. **Turn On the Water:** Water must always be flowing before starting the engine.
3. **Set the Spray Wand:** Point the spray wand in a safe direction and squeeze the trigger to release any remaining airlock until a steady stream of water flows out. Release the trigger.
4. **Engage the Choke:** Move the choke lever to the “Start” or “On” position if the engine is cold.
5. **Start the Engine:** Set the engine switch to “On,” pull the starter cord firmly. After it starts, gradually move the choke to the “Run” position.

**For Electric Pressure Washers**
1. **Water First:** Same as above—connect hose, turn on water, and purge air from the wand.
2. **Power Connection:** Plug the unit into a GFCI-protected outdoor outlet.
3. **Start the Motor:** Simply press the power switch or trigger. Electric models start instantly.
## **Common Beginner Mistakes & Troubleshooting**
**Why Won’t My Power Washer Start?**
* **No Water Flow:** This is the #1 cause of startup failure. The pump cannot run dry. Double-check your hose is on and not kinked.
* **Fuel Issues (Gas Models):** Old gasoline or an empty tank. Use fresh fuel.
* **Trigger Not Engaged:** Some machines require you to squeeze the spray gun trigger to start the motor.
**Maintaining Your Power Washer’s Health**
After each use, never just turn off the engine and walk away. For gas models, turn off the fuel valve and let the engine run until it stalls to clear fuel from the carburetor. For all models, **release the pressure** by turning off the machine and squeezing the trigger. Disconnect hoses and store in a frost-free location.
