Reasons Why Pressure Washer Chemical Injector Not Working Briggs And Stratton
Clogged Chemical Injector
The most common reason for a pressure washer chemical injector not working is a clogged injector. This can be caused by a build-up of sediment or debris in the injector, which can prevent the chemical from flowing through the injector and into the spray wand.
Blocked Orifice
Another common cause of a pressure washer chemical injector not working is a blocked orifice. The orifice is a small hole in the injector that allows the chemical to flow through. If the orifice is blocked, the chemical will not be able to flow through the injector and into the spray wand.
Defective Injector
In some cases, the pressure washer chemical injector may be defective. This can be caused by a manufacturing defect or by damage to the injector. If the injector is defective, it will not be able to properly inject the chemical into the spray wand.
Incorrect Chemical
Using the wrong chemical in your pressure washer can also cause the chemical injector to not work properly. Some chemicals are designed for specific types of pressure washers, and using the wrong chemical can damage the injector.
Improper Maintenance
Finally, improper maintenance of your pressure washer can also lead to a chemical injector not working properly. Failing to clean the injector regularly can allow sediment and debris to build up and clog the injector. Additionally, using the pressure washer at too high of a pressure can damage the injector.
