Product Overview
If the washer makes normal pressure but will not pull soap, the injector may be stuck with dried detergent or its check ball may be damaged. This replacement returns the venturi pickup point when the hose, filter, nozzle, and seals are otherwise correct.
Chemical injection works only in low-pressure mode on most washers. A high-pressure spray tip can make a good injector look failed.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice

Frequently Asked Questions
Q: Why does it not draw soap with the high-pressure tip? A: The injector normally needs low outlet pressure to create suction.
Q: Does this include the detergent hose? A: This listing is for the injector; confirm package contents if a hose or filter is also needed.
Q: Can dried soap block the old injector? A: Yes. Clean the line and filter before deciding the injector itself has failed.
