If your pressure washer is giving you trouble and won’t start, don’t rush to call a professional just yet. There are several detailed tips you can follow that might resolve the issue. Begin by examining the power switch and spark plug, ensuring both are in working order. Next, assess the quality of the fuel and verify if the choke is correctly positioned. Moreover, a closer look at the air filter and oil level can often reveal hidden problems.
Power Switch and Spark Plug
A common issue that may prevent a pressure washer from starting is an improperly set power switch or a faulty spark plug. First, confirm the power switch on the unit is turned on, as many people overlook this simple step.
Also, check the oil level; insufficient oil can trigger an electronic shutoff. Inspect the air filter for dust and dirt, and clean it if necessary. Examine the carburetor area and clean it to prevent any blockages.
If the engine still fails to start, remove the spark plug using a spark plug socket and inspect its tip for damage or corrosion. Replace the spark plug if the electrodes appear worn or damaged to ensure proper ignition.

Fuel Quality and Choke
Guaranteeing high-quality fuel and correctly positioning the choke are crucial steps in troubleshooting a pressure washer that won’t start.
First, inspect the fuel in your pressure washer. If it has been stored for an extended period, consider using a fuel stabilizer or mix it with fresh, high-octane fuel in a 4:1 ratio to improve performance.
Moreover, make sure the fuel line is open and unobstructed, allowing fuel to reach the engine efficiently.
When starting the engine, begin with the choke in the closed position to facilitate ignition; once the engine starts, gradually open the choke to maintain proper airflow.
These steps can greatly increase your chances of successfully starting your pressure washer.
Spark Plug Inspection
To diagnose starting issues, begin by thoroughly inspecting the spark plug for any signs of damage or wear. Remove the spark plug using a spark plug socket and carefully examine the tip. Look for evidence of corrosion, cracks, or a worn electrode. If the electrode is damaged, replacing the spark plug is necessary to restore proper function.
Moreover, inspect the spark plug wire for any corrosion or damage, which can impede starting as well. Make sure the wire is securely connected to the spark plug. Regularly replacing the spark plug every few years can prevent these issues from arising.
Engine Starting Tips
Prioritizing the basics of fuel, air, and spark is vital when troubleshooting engine starting issues.
Begin by confirming the fuel is fresh and consider mixing high-quality fuel with any stored fuel in a 4:1 ratio. Make sure the fuel line is clear and delivering properly to the engine.
Next, check the air intake; a clean air filter is necessary for proper engine function. Inspect the filter for dust and dirt, and clean or replace it as needed.
