Pressure Washer: Won't mix detergent with spray

Using the wrong spray tip to apply detergent can prevent the detergent from mixing properly with the spray. Use the low-pressure spray tip (usually the black tip) when applying detergent. A clog in the detergent siphon tube can also inhibit proper detergent mixing. Check the siphon tube for a clog and clean the tube if necessary. If the siphon tube is clear, then you’ll likely need to replace the chemical injection kit on your pressure washer.

Chemical injection system

The chemical injection system siphons detergent from the soap container and mixes the detergent with the spray. If the detergent doesn't flow through the system, check the chemical injection components for clogs or defective parts. Replace any defective chemical injection components.
