200 MBLE Black/gray water digital fill indicator

[JAXCMC]

Currently taking my 2018 200 MBLE across country and having a great time. camper is doing great...a few issues but nothing I couldn’t take care of my self.However with that said...my black water indicator always says it’s 2/3 full and my gray water never registers anything but empty. Soooooo is there anything I can do, or does this need to go to the shop? Thanks

The residue on the walls is causing the black tank to read wrong you could try leaving about 10 gals of water in it with or without some tank cleaner when you depart for your next stay and let it slosh during the drive that my clean things up. more then likely the gray has had a ground come loose may require dropping the underbelly to get at the wires.
