A pressure washer is a powerful tool that makes cleaning outdoor surfaces, vehicles, and equipment much easier and more efficient. However, one common issue that can hinder its performance is an airlock in the system. An airlock occurs when air gets trapped within the pump or hoses, preventing the flow of water and causing the pressure washer to malfunction or stop working altogether. Fortunately, fixing an airlock is often straightforward with the right steps. In this guide, we will walk you through how to identify and resolve an airlock in your pressure washer, ensuring it operates smoothly and effectively.
How to Fix Airlock in Pressure Washer
Understanding What Causes an Airlock
Before diving into the fixing process, it's important to understand what causes an airlock to form. Common reasons include:
- Low water supply or empty water source
- Incorrect setup or connection of hoses
- Running the pressure washer without water
- Leaks in hoses or fittings that allow air to enter
- Sudden changes in pressure or improper storage
Recognizing these causes helps in both preventing airlocks and effectively resolving them when they occur.
Steps to Fix an Airlock in Your Pressure Washer
Follow these step-by-step instructions to remove an airlock and restore your pressure washer's functionality:
1. Turn Off and Disconnect the Pressure Washer
- Ensure the pressure washer is turned off and unplugged from the power source if electric.
- Disconnect the high-pressure hose, water inlet hose, and spray gun for safety and ease of access.
2. Check and Clear the Water Supply
- Make sure your water source is turned on and providing a steady flow of water.
- If using a garden hose, ensure it is not kinked or blocked.
- Verify that the water inlet filter is clean and free of debris, as a clogged filter can cause air to enter the system.
3. Remove Air from the Pump
To purge trapped air, you'll need to prime the pump:
- With the water supply connected, hold the spray gun trigger and turn on the pressure washer.
- Keep the trigger pressed until water starts to flow steadily, indicating that air has been expelled.
- If no water flow begins after a few minutes, proceed to the next step.
4. Use the "Suck and Draw" Method
This technique helps to draw water through the system, pushing out airlocks:
- Disconnect the high-pressure hose from the spray gun.
- Submerge the water inlet hose into a bucket of clean water.
- Hold the trigger of the spray gun and turn on the pressure washer.
- This creates a vacuum that pulls water into the system, displacing trapped air.
- Once water flows steadily from the nozzle, turn off the pressure washer and reconnect the high-pressure hose.
5. Bleed the System Manually
If the airlock persists, manually bleeding the system can help:
- Loosen the fittings at the pump or hose connections slightly—be careful not to strip the threads.
- Turn on the pressure washer to allow air and water to escape through these openings.
- Once water begins to flow without bubbles, tighten the fittings securely.
6. Check for Leaks and Reconnect Everything
- Inspect all hoses and fittings for leaks or cracks that could allow air to enter.
- Replace damaged hoses or seals if necessary.
- Reconnect all hoses securely, ensuring a tight fit.
7. Test the Pressure Washer
After completing the above steps, turn on the pressure washer and activate the spray gun. Observe if the pressure builds up normally and the water flows consistently. If the system still struggles, repeat the priming and bleeding steps or consult a professional.
Additional Tips to Prevent Future Airlocks
- Always start with a full water supply and ensure hoses are properly connected before turning on the machine.
- Use clean, debris-free water to prevent clogging and air entering the system.
- Store your pressure washer properly in a dry, upright position to avoid internal air pockets forming.
- Regularly inspect hoses, fittings, and seals for wear and replace as needed.
- When not in use, run the pressure washer for a few seconds with water to clear out any remaining air and prevent stagnation.
Conclusion: Key Takeaways for Fixing Airlocks in Pressure Washers
Airlocks can be a frustrating obstacle, but with a systematic approach, they are easy to fix. The key steps involve ensuring a steady water supply, priming the system by drawing water through the pump, bleeding air from fittings, and inspecting hoses and seals for leaks. Preventive measures, such as proper storage and regular maintenance, also go a long way in avoiding future airlocks. By understanding the causes and following these straightforward procedures, you can keep your pressure washer running efficiently and ensure your outdoor cleaning tasks are completed with minimal hassle.
