Why Pressure Washer Injector Not Working
1. Dirty Injector
The injector is a small nozzle that sprays water through the pressure washer wand. If the injector becomes clogged with dirt or debris, it will not be able to spray water properly. This can cause the pressure washer to lose power and produce a weak stream of water.
2. Clogged Orifice
The orifice is a small hole in the injector that controls the flow of water. If the orifice becomes clogged with dirt or debris, it will restrict the flow of water and cause the pressure washer to lose power.
3. Broken Injector
If the injector is broken, it will not be able to spray water properly. This can cause the pressure washer to lose power and produce a weak stream of water.
4. Bad Gasket
The gasket between the injector and the pressure washer wand can wear out or become damaged. This can cause the injector to leak water and reduce the pressure of the spray.
5. Blocked Water Inlet
The water inlet on the pressure washer can become blocked with dirt or debris. This can prevent water from flowing into the pressure washer and cause the pressure washer to lose power.
How to Troubleshoot And Fix: Pressure Washer Injector Not Working
Check the Detergent Injector
Inspect the detergent injector for any clogs or blockages. Ensure that the detergent suction tube is not obstructed and is properly connected to the injector. Clean the injector and suction tube thoroughly to remove any debris or residue that may be causing the issue.
Inspect the Filter
Examine the filter in the detergent injector for any signs of dirt or debris. A clogged filter can prevent the injector from drawing detergent properly. Clean or replace the filter as needed to ensure unrestricted detergent flow.
Verify Water Supply
Check the water supply to the pressure washer to ensure that it is adequate. Insufficient water pressure can affect the performance of the detergent injector. Make sure that the water source is fully turned on and that the inlet hose is not kinked or obstructed.
Adjust Detergent Flow Rate
Adjust the detergent flow rate setting on the pressure washer to ensure that it is appropriate for the cleaning task at hand. A low flow rate may result in inadequate detergent suction
while a high flow rate can cause excessive detergent usage.
Examine the Detergent Hose
Inspect the detergent hose for any kinks
leaks
or damage. A damaged hose can disrupt the flow of detergent to the injector
leading to malfunction. Replace the hose if necessary and ensure that it is properly connected to the injector and detergent container.
Check for Air Leaks
Inspect the detergent injector and associated fittings for any air leaks. Air leaks can disrupt the suction of detergent and affect the overall performance of the injector. Tighten connections and replace any damaged seals to eliminate air leaks.
Test the Injector with Water
Perform a test run of the pressure washer with water only to verify the functionality of the injector. This can help determine if the issue is specific to the detergent suction system or if there are other underlying problems affecting the injector’s operation.
Professional Assistance
If troubleshooting the detergent injector does not resolve the issue
it may be necessary to seek professional assistance. A qualified pressure washer technician can diagnose and repair more complex injector problems
ensuring optimal performance of the pressure washer.
By following these troubleshooting steps
you can effectively address issues related to a pressure washer injector not
