There’s nothing more frustrating than gearing up for a day of pressure washing, only to find that no water is coming out of the sprayer gun. A pressure washer is a powerful tool for cleaning everything from driveways to siding, but like all equipment, it can run into issues. One common problem users face is when no water comes out of the pressure washer sprayer gun.
This blog will walk you through some common causes of this issue and provide troubleshooting steps to get your pressure washer back in action.
1. Check the Water Supply
The first thing to check when your pressure washer is not spraying water is your water supply. Without adequate water flow, your pressure washer will not function properly. Ensure that:
- The water faucet is fully turned on.
- The hose is securely connected to the pressure washer and the faucet.
- There are no kinks or twists in the hose restricting water flow.
Tip: If your home has low water pressure, your pressure washer may not be able to operate effectively. Make sure you have a strong, consistent flow of water before moving to the next steps.
2. Inspect the Water Inlet Filter
Most pressure washers have a water inlet filter that prevents debris from entering the machine. If this filter is clogged, it can block the flow of water, preventing it from reaching the sprayer gun.
- Turn off the pressure washer and disconnect the hose.
- Locate the water inlet filter (usually near where the hose connects).
- Remove and inspect the filter for any blockages like dirt or debris.
- Clean the filter with water or a soft brush and reinstall it.
3. Check for Airlocks in the Hose
Airlocks occur when air gets trapped inside the hose, interrupting the flow of water. This can prevent water from reaching the sprayer gun. To eliminate an airlock:
- Disconnect the spray gun from the hose.
- Turn on the water supply and allow water to run freely through the hose for a few minutes to remove any trapped air.
- Reattach the spray gun and test to see if the water is flowing.
4. Examine the Spray Gun and Nozzle
A clogged spray gun or nozzle is another common cause of water flow issues. Dirt, debris, or even small objects can get stuck in the spray gun or nozzle, preventing water from spraying. To troubleshoot:
- Turn off the pressure washer and disconnect the spray gun.
- Check the nozzle for any obstructions.
- Clean the nozzle with a needle or a nozzle cleaning tool (usually included with the pressure washer).
- Reattach the spray gun and test to see if water flows through it properly.
Tip: Using clean water in your pressure washer can help prevent nozzle clogs over time.
5. Inspect the High-Pressure Hose
Sometimes, a problem with the high-pressure hose itself can stop water from reaching the spray gun. Look for any signs of damage, such as:
- Leaks: If the hose has any leaks, it can affect water pressure and stop water from reaching the sprayer gun. Replace the hose if necessary.
- Kinks or Twists: Ensure the hose is completely straight and free from any sharp bends or kinks that might restrict water flow.
- Loose Connections: Make sure all connections are tight and secure at both ends of the hose.
6. Check the Pump
If your pressure washer is still not working, the issue may lie with the pump. The pump pressurizes the water before it reaches the sprayer gun. If the pump is not functioning correctly, you won’t have any water pressure. Here’s how to check the pump:
- Make sure the pressure washer is plugged in (for electric models) or that it has enough fuel (for gas-powered models).
- Listen for unusual noises from the pump that might indicate an issue.
- If the pump appears to be faulty, refer to the manufacturer’s manual or contact a professional for repairs.
7. Look at the Unloader Valve
The unloader valve controls the pressure within the pressure washer. If this valve is not working correctly, it may stop water from flowing out of the sprayer gun. To troubleshoot:
- Turn off the pressure washer and locate the unloader valve.
- Check for any signs of damage or obstruction.
- Clean or adjust the valve according to the manufacturer’s instructions.
If the unloader valve is defective, it may need to be replaced.
8. Consult the Manual
Finally, if you’re unable to identify the cause of the issue, refer to the user manual for your specific pressure washer model. The manual will contain troubleshooting steps and detailed diagrams that can help you diagnose and resolve the problem.
When to Call a Professional
If you’ve gone through these steps and your pressure washer still isn’t working, it might be time to call in a professional for repairs. Issues like a faulty pump or broken unloader valve require specific tools and expertise that are best handled by an expert.
