Troubleshooting Your Electric Pressure Washer: Why It Won't Turn On
If your electric pressure washer won't turn on, you're not alone. This is a common issue that many users face, but don't worry, it's often a simple fix. In this guide, we'll walk you through some of the most common reasons why your electric pressure washer might not be turning on and provide you with practical solutions.
Understanding Your Electric Pressure Washer
Before we dive into the troubleshooting process, it's helpful to understand the basic components of an electric pressure washer. These include:
- The motor
- The pump
- The trigger gun and wand
- The power cord
- The GFCI (Ground Fault Circuit Interrupter) outlet
Check the Obvious: Power and Safety Features
Before you start dismantling your pressure washer, let's ensure that the problem isn't something simple and easily fixed.

Check the Power Source
First, make sure your pressure washer is properly plugged into a working outlet. Test the outlet with another appliance to ensure it's not the issue. Also, check the power cord for any signs of damage. If the cord is damaged, it's best to replace it to avoid any safety hazards.
Inspect the GFCI Outlet
Electric pressure washers come with a GFCI outlet for safety reasons. If the GFCI has tripped, it won't allow power to flow to the washer. Reset the GFCI and try turning on your pressure washer again.
Inspect the Motor and Pump
If your pressure washer still isn't turning on, it's time to check the motor and pump. These are the most common culprits when a pressure washer won't turn on.

Check the Motor
The motor is the heart of your pressure washer. If it's not working, your washer won't turn on. Inspect the motor for any signs of damage or wear. If the motor is making unusual noises or smells burnt, it might be time to replace it.
Inspect the Pump
The pump is responsible for creating the high-pressure water stream. If it's not working, your pressure washer won't turn on. Check the pump for any leaks or signs of damage. If you find any, you might need to replace the pump.
Other Possible Causes
While the motor and pump are the most common causes, there are other issues that could prevent your pressure washer from turning on.
Thermal Overload Protection
Some pressure washers have a thermal overload protection feature that automatically shuts off the washer if it overheats. If this feature has been activated, you'll need to allow the washer to cool down before trying to turn it on again.
Faulty Switch or Circuit Breaker
If the switch on your pressure washer is faulty or the circuit breaker has tripped, your washer won't turn on. Test the switch and reset the circuit breaker to see if this is the issue.
When to Call a Professional
If you've checked all the components and your pressure washer still won't turn on, it's time to call a professional. Some issues, like a faulty motor or pump, require professional repair. Always remember, safety first. If you're not comfortable performing any of these checks or repairs, don't hesitate to call a professional.
Preventative Maintenance
To prevent your pressure washer from not turning on in the future, perform regular maintenance. This includes cleaning the washer, checking the oil and filters, and storing the washer properly when not in use.
| Maintenance Task | Frequency |
|---|---|
| Clean the washer | After each use |
| Check the oil and filters | Every 25 hours of use |
| Store the washer properly | After each use |
