My WIF lite would come on usually after a sharp turn at an intersection.
I put the driver-side up on ramps, so the HFCM drain was pointed downhill.
I removed the drain plug and sprayed carb-cleaner in and out came brown goo (algae). I continued to spray and aim the straw around to all the corners/sides top/bottom until no more goo came out.
I let it dry/drain for a few minutes and then put the plug back in.
NO WIF for nearly a year now (fingers crossed
)
It's a cheap attempt to clean the sensor, and the good cleaning isn't a waste itself. If your WIF returns THEN get a new sensor..

It's not that it's a bad design, the HFCM is used on many different types of diesel trucks. The issue is that all the fuel passes that sensor and one bad tank or water or algae and it's going to go off. Likely need to follow the instructions above and clean it out with carb cleaner, use lots and wash and rinse it all out, both from the water sensor side and inside the filter housing with the water drain open. If all else fails, a new buddy is warranted. Also, I would put the drained fuel Ina clean glass container with a lid, let it sit. Much easier to see small water droplets in glass with a flash light. I think you can detect far less water than the can idea above.

If you need to replace the sensor here is the kit on Ebay with
the new drain valve.

I had a WIF light come on after 3-5 minutes of driving. after letting my fuel get below a 1/4 tank. and my plug was stripped out. so i picked up a new manifold for the hfcm. there was all kinds of garbage in the area behind the plug. (enough that even if i had been able to remove plug i dont think the cleaner wouldve been able to get it out...) but no water. my guess if you may have some trash built up in there and its causing the sensor to fault.
