WashR PRO | There is the presence of water in the oil

If you’re seeing milky or contaminated oil in your WashR PRO, here’s what might be causing it — and how to fix it:

Possible Cause	What You Can Do
High humidity in the air	Check and change the oil more frequently in humid environments to prevent moisture build-up.
Worn piston packing or oil seal	Contact bigboi customer support — your internal seals may need inspection or replacement.
Not performing regular maintenance	Stick to your service schedule — especially oil changes — to avoid long-term pump damage and oil contamination.
Using the wrong oil	Only use non-detergent API SF SAE 10W/30 or 15W/40 oil. Avoid detergent oils — they create foam and reduce performance.

Still unsure? If you're concerned about oil contamination or not sure what to do next, reach out to our support team — we're here to help.
