A pressure washer is a powerful tool that can be used for a variety of tasks, from cleaning driveways to removing graffiti. However, when the chemical injector is not working properly, it can be a major inconvenience. This is because the chemical injector is responsible for delivering the cleaning solution to the pressure washer wand. Without the chemical injector, the pressure washer will not be able to effectively clean surfaces.
In this troubleshooting guide, I will walk you through the steps to diagnose and resolve the issue of a chemical injector that is not working on a pressure washer. By following these steps, you can quickly and easily restore functionality to your pressure washer and get back to cleaning.
Why Chemical Injector Not Working On Pressure Washer
Blocked chemical injector nozzle:
The most common cause of a chemical injector not working is a blocked nozzle. This can be caused by dirt, debris, or chemical residue. To fix this, remove the nozzle and clean it with a small brush or needle.
Incorrect chemical injector settings:
The chemical injector may not be working properly if the settings are incorrect. Check the owner’s manual for the correct settings for your pressure washer.
Damaged chemical injector:
If the chemical injector is damaged, it will need to be replaced.
Low pressure:
If the pressure washer is not producing enough pressure, the chemical injector may not be able to function properly. Check the pressure washer’s pump and make sure it is working properly.
Faulty electrical connection:
If the chemical injector is not getting power, it will not work. Check the electrical connection to the chemical injector and make sure it is secure.
How to Troubleshoot And Fix:
Symptoms of a Chemical Injector Not Working
There are a few telltale signs that your chemical injector may not be working properly. These include:
The chemical solution is not coming out of the wand when you trigger the sprayer:
This is the most obvious symptom, and it means that the injector is not sending the chemical solution through the hose to the wand.
The chemical solution is coming out of the wand in a weak or inconsistent stream:
This can be caused by a blockage in the injector or a problem with the pressure regulator.
The chemical solution is coming out of the wand in a fine mist:
This is usually caused by a problem with the nozzle.
The chemical solution is not mixing with the water properly:
This can cause the chemical to be ineffective and can damage your surfaces.
Troubleshooting a Chemical Injector
If you suspect that your chemical injector is not working properly, there are a few things you can do to troubleshoot the problem.
1. Check the chemical solution:
Make sure that the chemical solution is properly mixed and that it is not expired. If the chemical solution is too thick, it may not be able to flow through the injector properly. If the chemical solution is too thin, it may not be effective.
2. Check the injector:
Look for any blockages in the injector. You can do this by removing the injector from the pressure washer and inspecting it closely. If you find any blockages, you can try to clear them out with a small brush or needle.
3. Check the pressure regulator:
The pressure regulator controls the amount of pressure that is sent to the injector. If the pressure regulator is set too high, it can damage the injector. If the pressure regulator is set too low, it can cause the chemical solution to be ineffective.
4. Check the nozzle:
The nozzle is the part of the injector that sprays the chemical solution out of the wand. If the nozzle is clogged or damaged, it can prevent the chemical solution from coming out properly. You can try to clean the nozzle with a small brush or needle. If the nozzle is damaged, you will need to replace it.
Fixing a Chemical Injector
If you have troubleshooted the problem and determined that the chemical injector is not working properly, you will need to fix it.
1. If the chemical solution is the problem, you can try to thin it out by adding more water. If the chemical solution is still too thick, you may need to replace it:
2. If the injector is clogged, you can try to clear it out with a small brush or needle. If the injector is still clogged, you may need to replace it:
3. If the pressure regulator is the problem, you can try to adjust it. If the pressure regulator is still not working properly, you may need to replace it:
4. If the nozzle is the problem, you can try to clean it with a small brush or needle. If the nozzle is still not working properly, you may need to replace it:
If you are unable to fix the chemical injector yourself, you can take it to a qualified technician for repair.
Preventing Chemical Injector Problems
There are a few things you can do to prevent chemical injector problems:
Use the correct chemical solution:
Make sure that the chemical solution is compatible with your pressure washer and that it is not expired.
Mix the chemical solution properly:
Follow the instructions on the chemical solution label carefully.
Clean the chemical injector regularly:
Inspect the chemical injector regularly for any blockages or damage. Clean the chemical injector with a small brush or needle as needed.
Store the chemical injector properly:
Store the chemical injector in a cool, dry place.
By following these tips, you can help to prevent chemical injector problems and keep your pressure washer running smoothly.
FAQs: Chemical Injector Not Working on Pressure Washer
Why is my chemical injector not working?
There are a few possible reasons why your chemical injector may not be working. Here are some of the most common:
The injector is clogged: This is the most common cause of a chemical injector not working. The injector can become clogged with dirt, debris, or chemical residue. To fix this, you will need to clean the injector.
The injector is not getting enough pressure: The injector needs a certain amount of pressure to operate properly. If the pressure is too low, the injector will not be able to draw the chemical into the sprayer. To fix this, you will need to check the pressure of your pressure washer and make sure it is within the manufacturer’s specifications.
The injector is not getting enough water: The injector also needs a certain amount of water to operate properly. If the water flow is too low, the injector will not be able to draw the chemical into the sprayer. To fix this, you will need to check the water flow of your pressure washer and make sure it is within the manufacturer’s specifications.
The injector is not properly installed: The injector must be installed correctly in order to work properly. If the injector is not installed correctly, it will not be able to draw the chemical into the sprayer. To fix this, you will need to reinstall the injector according to the manufacturer’s instructions.
The injector is defective: In rare cases, the injector itself may be defective.

How do I increase the pressure of my pressure washer?
There are a few ways to increase the pressure of your pressure washer. Here are some of the most common:
Increase the water flow: The more water that flows through the pressure washer, the higher the pressure will be. To increase the water flow, you can open the water valve wider or increase the speed of the pump.
Use a higher-pressure nozzle: The pressure of the spray is determined by the nozzle that you are using. To increase the pressure, you can use a nozzle with a higher pressure rating.
Clean the filter: A clogged filter can restrict the flow of water and reduce the pressure of the spray. To increase the pressure, you should clean the filter regularly.
Replace the pump: If the pump is worn out, it may not be able to generate enough pressure. To increase the pressure, you may need to replace the pump.
