Gray Water not empty, only 1 gate valve

It's a D650, meaning 6.5' floor. The camper is TINY, yet it has a full bathroom, so as you can imagine things are pretty cramped.

Where on earth would you fit TWO 38 gallon waste tanks?

I would guess that the reason you have 3 tank level indicators, a black, grey and fresh, is because that is the normal off the shelf unit. I would imagine that somewhere there is a jumper between the sensor and the panel B & G so that it would appear all indicators are working. If you took delivery of a new unit and only the black indicator lites up and not the grey you'd complain the grey wasn't working. Easy way for the mfg to continue the deceptive marketing as depicted in the manual.

Glad you solved the issue, now you can take a shower without the foot bath:)

Sorry, a couple of you were correct and brilliant! Thanks.

Buzzcut was right, there is only 1 tank for both grey and black. (bummer for me) Here's what I found, the grey water 1 1/2" line was blocked just past the shower drain. I snaked down from the vent on top (was plugged due to previous owner not replacing the vent cover and leaves and debris blocked the line) I did install a new vent cover when I acquired the camper. I flushed the line thoroughly with pressure and found pieced of white plastic, (old broken vent cover??) leaves, dirt in the flush water. Everything drains well now. Strange that the indicator Tank 1 and Tank 2 both show empty now??? Thanks for the help.

Open the known valve and turn on the shower. Does water come out?

Still baffled over 1 gate valve.

I think the people here answered it already? You do have 2 tanks.

1 fresh water
1 black/grey

There should be a large gate valve to dump the black/grey.
Then there should be a smaller valve somewhere to dump your fresh water.

Having the 3 indicators for fresh, grey, and black is probably just because its part of the display panel. THey use the same display for models that have separate black and grey tanks is my guess.

Thanks for all the thoughts...Haven't had time to test all the theories, I will try tomorrow and post the results. Yes there are 3 electronic tank indicators Fresh water, grey water and black water. Still baffled over 1 gate valve. I'm not ready to pull up the floor to check the tanks. I did shine a flashlight into the empty 3" drain, nothing I could see, I will do the same again with a telescoping mirror. Crappy job!

I would not trust the sensor readings as gospel.. If you open the valve and nothing comes out, it's gotta be empty?
