Water In Fuel

[Ford331sc]

I have a 2005 6.0 F250. My water in fuel indictor has come on so I drain the plug that is located on the driver side frame rail. After doing this a starting the truck back up the water in fuel indictor still comes back on is there something that I’m missing or is there other issues now and need to take it to Ford?

Thanks for any help in advance

you may have to do it a few times. try doing it again till you get the light off. My buddy had to do this about 3-4 times till his light turned off
