If your Hart pressure washer soap injector is not working, the most likely problem is a failed chemical injection kit. This kit contains the parts needed to repair most injector-system problems, including the soap injector, injector spring, injector ball, injector o-ring, and related seals. A damaged or worn part can cause your pressure washer soap dispenser not to work, prevent the pressure washer from dispensing soap, or make it draw only water even when the detergent siphon and soap filter are in place. Replace the chemical injection kit when the injector is worn, damaged, or no longer pulls detergent through the siphon tube. Before installing the replacement, check that the siphon tube is connected securely and that the soap filter and black soap nozzle are not blocked. Use the correct low-pressure soap nozzle or setting, since the injector usually will not draw detergent at high pressure. Whether you call it a pressure washer soap problem, a pressure washer detergent problem, or a chemical injector problem, enter your Hart pressure washer model number to find the exact replacement chemical injection kit and other parts that fit your specific machine.
