Most Common Reasons Of Pressure Washer Injector Not Working
Most Common Reasons Of Pressure Washer Injector Not Working
Clogged Injector
The most common reason for a pressure washer injector not working is a clogged injector. This can be caused by a build-up of dirt, debris, or mineral deposits in the injector. To fix this problem, you will need to remove the injector from the pressure washer and clean it with a degreaser or carburetor cleaner.
Blocked Orifice
Another common cause of a pressure washer injector not working is a blocked orifice. The orifice is a small hole in the injector that allows the water to flow through. If this hole becomes blocked, it will prevent the water from flowing through the injector and out the nozzle. To fix this problem, you will need to remove the injector from the pressure washer and clean the orifice with a small needle or pin.
Damaged Injector
In some cases, the injector itself may be damaged. This can happen if the injector is dropped or struck by something hard. If the injector is damaged, it will need to be replaced.
Incorrect Fuel Mixture
The fuel mixture for a pressure washer injector is very important. If the mixture is too rich or too lean, it can cause the injector to not work properly. To fix this problem, you will need to adjust the fuel mixture so that it is correct.
Faulty Electrical Connection
The injector in a pressure washer is typically controlled by an electrical circuit. If there is a problem with the electrical connection, it can prevent the injector from working properly. To fix this problem, you will need to check the electrical connection and make sure that it is secure.
Faulty Pressure Washer
In some cases, the problem may not be with the injector itself, but with the pressure washer itself. If the pressure washer is not working properly, it can cause the injector to not work properly. To fix this problem, you will need to troubleshoot the pressure washer and fix the problem.
How to Troubleshoot And Fix: Pressure Washer Injector Not Working
Symptoms of a Pressure Washer Injector Not Working
There are a few different symptoms that can indicate that your pressure washer injector is not working properly. These include:
Low pressure:
If you’re not getting the same amount of pressure from your pressure washer as you used to, it could be a sign that the injector is not working properly.
Weak spray:
Another sign of a problem with the injector is a weak spray. The water may not be coming out with as much force as it used to, or it may be coming out in a thin stream instead of a powerful jet.
Nozzle clogging:
If your nozzle is clogged, it can also cause the pressure washer to lose pressure. You can usually clear a clogged nozzle by soaking it in a vinegar and water solution for a few minutes.
Burning smell:
If you smell burning coming from your pressure washer, it could be a sign that the injector is overheating. This can be caused by a number of things, such as a dirty filter, a clogged nozzle, or a problem with the pump.
Troubleshooting a Pressure Washer Injector
If you’re having problems with your pressure washer injector, there are a few things you can check to try to troubleshoot the problem.
First, check the filter:
A dirty filter can restrict the flow of water to the injector, which can cause a loss of pressure. To check the filter, remove it from the pressure washer and clean it with warm, soapy water.
Next, check the nozzle:
A clogged nozzle can also cause a loss of pressure. To check the nozzle, remove it from the pressure washer and soak it in a vinegar and water solution for a few minutes.
If the filter and nozzle are clean, the next step is to check the pump:
The pump is responsible for generating the pressure for the pressure washer. If the pump is not working properly, it can cause a loss of pressure. To check the pump, turn on the pressure washer and listen for any unusual sounds. If you hear a whining or grinding noise, it could be a sign that the pump is not working properly. You may need to have the pump repaired or replaced.
If you’ve checked the filter, nozzle, and pump and the problem persists, you may need to replace the injector:
Injectors are relatively inexpensive and can be replaced easily. To replace the injector, follow the instructions in your pressure washer’s owner’s manual.
Preventing Pressure Washer Injector Problems
The best way to prevent pressure washer injector problems is to keep your pressure washer clean and well-maintained. Here are a few tips:
Change the filter regularly:
A dirty filter can restrict the flow of water to the injector, which can cause a loss of pressure.
Soak the nozzle in a vinegar and water solution every few months:
This will help to prevent the nozzle from clogging.
Inspect the pump regularly for signs of wear and tear:
If you notice any unusual sounds coming from the pump, have it repaired or replaced as soon as possible.
Store your pressure washer in a cool, dry place:
This will help to prevent the pump from overheating.
By following these tips, you can help to keep your pressure washer injector working properly and avoid costly repairs.
