How to Start a Pressure Washer That Has Been Sitting: Step-by-Step Guide
Step 1: Inspect the Unit
Before attempting to start your pressure washer, inspect it thoroughly. Check for any signs of damage, leaks, or loose parts. Ensure that all components, such as the hose and connections, are intact.
Step 2: Check and Replace Fluids
Oil and fuel can degrade over time. If possible with your unit, check the oil level and quality; if it's dark or has debris, replace it with fresh oil. If your pressure washer runs on gasoline, drain any old fuel and add new gasoline. Old gas can become stale and affect performance.
Step 3: Inspect the Air Filter
If your unit has an air filter, remove it and check for any dirt or damage. A clogged or damaged air filter can prevent the engine from starting or running smoothly. Clean or replace the air filter as needed.
Step 4: Check the Spark Plug (Gas Washers)
Inspect the spark plug for any carbon build-up or wear. If necessary, clean it with a wire brush or replace it to ensure a strong ignition.
Step 5: Flush the Water System
Attach the water hose to the pressure washer and run water through the system without starting the engine. This step helps remove any debris or buildup in the water pump and hoses.
Step 6: Prime the Engine (Gas Washers)
If your pressure washer has a priming bulb, press it a few times to prime the engine. This step ensures that fuel reaches the carburetor and facilitates a smooth start.
Step 7: Start the Pressure Washer
Set the choke to the appropriate position, turn on the fuel valve (if applicable), and pull the starter cord firmly. If the engine does not start after a few tries, double-check the fuel and spark plug connections.
Conclusion
Following these steps can help ensure your pressure washer starts up smoothly after sitting idle. Regular maintenance and proper storage can make future starts easier and prolong the life of your equipment. If you encounter persistent issues, consider consulting a professional for a thorough inspection.
