Why Won’t My Pressure Washer Start? Troubleshooting Tips for How to Start a Pressure Washer That Won’t Start
If you’re staring at mold, grime, and rust on your property, a power washer is the most effective way to remove them.
It can be frustrating when you pull your starter cord or flip on your power switch and only hear a few sputters. You sit there perplexed: why won’t my pressure washer start?
There isn’t a one-size-fits-all solution if your pressure washer won’t start. You may have a simple fix that takes just a few minutes, or a complex issue that requires professional repairs.
Start With the Obvious
If your pressure washer won’t start, you might begin to fear the worst, envisioning costly downtime and repairs. However, sometimes the answer to how to start a pressure washer that won’t start is simple.
First, ensure your machine is turned on and has power. Check for fuel in the tank for gas-powered machines. With electric power washers, verify that your machine is plugged into the outlet and/or has a battery charge.
Your machine may also have safety features or switches that prevent it from starting correctly. Inspect these areas and toggle them on and off to test for proper functioning.
Another common “simple” fix is an empty water tank or issues with your hose connections. Many pressure washers will refuse to start without water to protect their internal components.
Fuel System Problems (Gas Models Only)
I tried those basic fixes, but they didn’t work. So why won’t my pressure washer start?
From this point, you’re likely dealing with a mechanical issue of some kind. You can handle some of the reasons why a pressure washer won’t start, but others will require professional assistance.
Power issues are a common reason. For gas models, thoroughly inspect your fuel system. Old gasoline can be problematic, especially after your machine has been in storage for the winter. Emptying and replacing stale gas may fix the issue.
You should also check the fuel filter for cracks or blockages. Any leaks or excessive carbon buildup could be signs that you need to replace an internal part.
Electrical and Switch Failures (Electric Models Only)
If your electric pressure washer won’t start, you’ll use different troubleshooting methods compared to a gas-powered one.
Many of the issues are due to failures that occur at some point in the electrical process. A faulty outlet or power card can cause the system to fail. If you have a GFCI outlet, you should hit the reset button before plugging in your machine.
If you hear a click or see flickering lights and wonder, why won’t my pressure washer start, you might have a more serious issue, such as a switch or motor failure. In that case, we recommend bringing it in for an expert opinion.
Inspect the Spark Plug and Ignition System
When your ignition system isn’t working, your pressure washer won’t start. Inspect your spark plugs for any signs of damage, including carbon deposits or oil leaks. You can clean the spark plug and give it another try, but many of these issues require a replacement.
Replacing a fresh spark plug is a reliable method for how to start a pressure washer that won’t start. However, if you’re still experiencing issues, you may have a damaged ignition coil or flywheel, which will require professional repair.
Check the Air Filter and Exhaust Blockage
If you’ve tried these initial methods for how to start a pressure washer that won’t start but are still experiencing trouble, your machine might have an internal blockage.
A clogged air filter on a pressure washer can prevent it from starting entirely. Inspect the filter for any leftover dirt or carbon buildup. You can either clean or replace the filters, depending on their condition–use your best judgment and test your machine thoroughly.
Repeat the same inspection and cleaning process with your power washer’s exhaust. If you notice signs of black smoke or frequent engine stalls, there may be an obstruction in the engine.
Pump Pressure Lock or Water Flow Blockage
Not all starting issues with your pressure washer are engine-related. If your pump is malfunctioning, your machine might refuse to start.
The pressure lock on your pump traps pressure in the system, preventing water leaks. You should be able to disengage this lock with a trigger located somewhere on your machine; however, if this part malfunctions, the lock will block all pressure, preventing it from starting.
If there is a blockage in water flow from your pump, your machine’s safety features will hinder the ignition process. This is usually a good thing, as starting a power washer without water can damage your internals due to high heat.
You’ll need to address blockages caused by mechanical issues, such as kinked hoses, obstructions in your nozzles, or clogs inside the pump, to get your machine working again.
When It’s Time to Stop Troubleshooting and Call a Pro
You’ve gone through the checklist and tried our tips for how to start a pressure washer that won’t start.
Yet after that, you’re still left there thinking, why won’t my pressure washer start?
If the quick tweaks work, your power washer is likely experiencing a complex mechanical problem. At that point, it’s best to have a professional look at it.
Signs Your Pressure Washer Needs Professional Repair
Many of the reasons why a pressure washer won’t start are beyond the reach of quick DIY fixes.
There are several warning signs you need to watch out for.
You’re likely dealing with one of these issues if your machine is constantly sputtering, leaking oil or fluid, making harsh grinding noises, or emitting a smoky or fiery smell. Additionally, if your electric power washer is tripping your circuit breakers or blowing fuses, that’s a clear sign that you need professional help as soon as possible.
Once you’ve exhausted all of the basic tweaks like spark plugs, air filters, and hose replacements, there’s not much more you can do. Your best bet is to have a professional look at your internal components, as they’ll have a clear idea of what’s wrong and the tools to fix it.
Don’t Risk Damage by Forcing It to Start
When your power washer first refuses to start, try flipping it on and off a couple of times to diagnose the issue.
But you don’t want to overdo this process. Brute force isn’t enough to get your power washer starting again. If you try to force it to start, you may eventually flood the engine or damage your starter. Electric models may experience a blown fuse or circuit damage, while gas machines will typically result in damage to the carburetor or ignition internals.
Suddenly, a once relatively simple replacement develops into a massive issue. It’s not worth it to double or triple your pressure washer repair costs just to give it a few more tries.
Instead, we recommend consulting with a knowledgeable repair shop. They’ve seen the issue you’re experiencing hundreds of times and can quickly diagnose and fix it. Professionals will save you time and money and extend the lifespan of your machine.
