      If detergent fails to mix with the spray in your Hyundai Pressure Washer, it could be due to a few reasons. First, check that the detergent siphoning tube is fully submerged in the detergent. Second, the detergent siphoning tube or filter might be clogged or cracked, requiring cleaning or replacement. Lastly, a high-pressure spray tip might be installed, so replace it with a low-pressure spray tip.
