Water in Fuel Alarm / Limp Mode.

Variant 1

System

Fuel (Water)

Symptom

Water in Fuel Alarm / Limp Mode.

Diagnosis & fix steps

LOGIC: Water-in-Fuel (WIF) sensor resistance low. ACTION: Drain the primary fuel filter bowl. If the light stays on after draining, check the sensor pins for "green rot" corrosion.

Red Seal field insights

PRO-TIP: In Ontario winters, ice in the bowl can trip this code. Warm the filter with a heat gun to see if the resistance returns to normal before replacing the sensor.

Variant 2

System

Fuel

Symptom

Water in Fuel Light.

Diagnosis & fix steps

LOGIC: Conductivity probe in the water separator detects water. ACTION: Drain the primary fuel filter bowl immediately.

Red Seal field insights

PRO-TIP: If the light stays on after draining, the probe is likely "filmed" over with algae. Remove and clean the pins with a scotch-brite pad.
