Read this ...... lots of info here. Suggest you take a look at the Tech Folder at the top of the 6.0 forum forum.

The sensor is located on the HFCM cover. While lying under the drivers side of the truck looking at the HFCM, the sensor will be the wire on the right side of the cover down at the bottom. Not sure how to clean it, but it will come out with the cover so maybe remove the cover and try to clean it. When getting a new cover you get a new sensor so that's an option as well.
Are you draining the fuel / water from the drain plug, or are you thinking you're getting the water out just by the filter?

I thought I had a Pic of one all torn apart
But if you look in the Link I posted at the Second Pic Down the arrow points to the WIF Drain and see how the Housing around that area kinda Square thats where the sensor is and thats the area that needs to be opened up and Cleaned Out
I will keep looking for the better pic and will post if I find it

ISSUE:
Some 2003-2005 F-Super Duty vehicles built prior to 9/22/2004, 2003-2005 Excursion vehicles built prior to 1/10/2005, and 2004-2005 E-Series vehicles built prior to 9/16/2004 and equipped with a 6.0L diesel engine, may exhibit an intermittent / flickering water in fuel (WIF) lamp. The intermittent condition may be more prominent while turning corners, braking, or during uphill/downhill driving.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit a continuous WIF lamp on, even without the presence of water, due to debris in the reservoir or corrosion on the WIF sensor pins located in the manifold. Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit both intermittent / flickering and continuous WIF due to corrosion and the lack of new calibration.
ACTION:
Use the following Service Procedure based upon the customers symptom.

Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit both intermittent / flickering and continuous WIF due to corrosion and the lack of new calibration.
ACTION:
Use the following Service Procedure based upon the customers symptom.
SERVICE PROCEDURE
- For intermittent / flickering WIF lamp condition reprogram the powertrain control module (PCM) to the latest calibration using the IDS release B32.11 or higher. Calibration files may also be obtained at Motorcraft.
- If the WIF lamp continuously illuminates without the presence of water, this may be due to corrosion on the sensor pins or sediment build up in the water reservoir.
- Drain the horizontal fuel conditioning module (HFCM) reservoir and look for significant corrosion debris or sediment in the fluid drained from the reservoir. Remove the WIF sensor and inspect for corrosion on the pins. Remove the WIF Senor by first disconnecting the electrical connector, then using channel locks, rotate the WIF sensor at least 45 degrees counterclockwise. If there is corrosion / sediment on the pins, proceed to Step b. If there is not, refer to PC/ED lead diagnostics and do not proceed with the TSB.
- If corrosion on the pins is causing the WIF lamp to illuminate, replace the WIF sensor with service kit, following the WIF sensor installation instructions in the kit.
- If there was significant corrosion debris or sediment drained from the reservoir, clean the housing of the HFCM of any debris following the HFCM cleaning procedure. It is not necessary to replace the Manifold or HFCM assembly.
- Vehicles with both an intermittent and continuous WIF light due to corrosion are to follow actions 1 and 2 as described above, referring to the vehicle built dates and application.
- Disconnect both battery ground cables. Refer to Workshop Manual, Section 414-01.
- Raise and support the vehicle. Refer to Workshop Manual, Section 100-02.
- Disconnect the fuel pump, heater, water in fuel electrical connectors from HFCM (Figure 1).

Figure 1 - Article 06-22-12 - Disconnect HFCM electrical harness from main vehicle harness.

Don't use brake cleaner. Use carb cleaner. Using heat, bend the last 1/2 inch of the spray straw 90 degrees. Stick the straw into the drain hole, with the spray directed toward the front of the truck and spray. This should flush the gunk out through the drain hole. I had a problem with my WIF light and this fixed it. Since then, I do this each time I change the filter. BTW, this was not my idea. Just one more money saving idea that I learned on FTE.
