Water in Fuel Indicator On

Diagnosis & fix steps

LOGIC: Water in Fuel Condition Detected. ACTION: Drain the primary fuel filter housing immediately. Clean the water-in-fuel sensor probes inside the bowl to remove conductive metallic slime or film.

Red Seal field insights

Physics: Water is denser and more conductive than diesel. When it fills the bottom of the bowl, it bridges the sensor probes, completing the circuit to flag the warning.
