0 The Heinz Posted August 13 Share Posted August 13 The WIF sensor could be going bad, especially if it was the bowl type primary filter and was cleaned with brake clean. I saw similar failures in KW T680's; I was new and was taught to clean the bowl with brake clean by the older guys in the shop, turns out that tends to kill the WIF sensor. Live and learn I guess. If it's the bowl type, I think the entire bowl will need to be replaced, I don't think the sensor is separate. You'd want others to tell you more, I can shotgun ideas at you but it would be little more than educated guesses.
