Water in fuel display

[BEACH]

I have two green indicator lights under the fuel gauge that indicate water in the fuel. I drained some fuel out of the separator into a clear jar. Only diesel, no presence of water.
What am I missing?

2013 open road 34qfa, Cummins diesel

Are you sure that the lights are for water in fuel and not DEF quantity? The symbol for water in fuel is normally a yellow fuel pump with three drops on one side.

Exactly . . . Water indicator is yellow and the green indicators is DEF level

Excellent…did not think of the DEF tank….I have about 1/2 tank
Thank you!

Yes, I believe each light indicates 1/4

Is the 34qfa an Allegro Red or an Allegro Open Road. I didn't think the "Open Road" had a diesel engine. I have a 2018 Open Road with a gas engine, so did some of the earlier Open Road models have a diesel engine, and is it in the rear or front? Just a little confused.
Thanks,

They changed the designations around 2017-2018 by dropping the Open Road designation on the REDs. Our 2015 was an Allegro Open Road RED branded on the logos.

Thanks for clearing that up Lt Dan. I just always think of "Open Road" as Tiffin's gas model class A, but now know to be careful in my assumptions.
I guess RV manufacturers like to keep their customers confused. Tiffin uses the "Allegro" name in several different models also, which is sometimes confusing.

I have a similar problem with my Cummins engine. It has happened several times, always when raining or in high humidity. Never found the cause.

A bad connector at the fuel filter.
