Crazy Problem with Grey Water Tank

This is opposite to everyone else's holding tank problem. My grey water tank still reads full even though I just dumped both holding tanks. Normally it's the black water tank that gives false readings.

So what's the problem here and how do I circumvent it? TIA

I did find that the tower of doom in the black tank can be removed with a judicious application of ice cubes, cold water and quick sharp turn driving.

Help!

Congrats on clearing the black pyramid. If your grey tank uses electro conductive sensors to read the level, even the grey tank can have something coating the probes - causing current to flow. Use the Geo Method to clean the tank and sensors.

The other source of this kind of problem would be in the panel...much more work to fix, so I would start with the Calgon Mixture

I thank you for the link. I will be adding the concoction to the tanks tomorrow and we'll see what happens.

while various concoctions will fix the factory sensors for awhile, only a seelevel 709 system will fix them forever.

Never had one that gave true readings after being in service and filled a few times. I have used a lot of hot water and laundry detergent after dumping and then driving home or to the next destination. Works most of the time, but no guarantee.

I just may have to go that route again. I installed a seelevel system in our 24 foot C Class and it is still working.

Are you talking about replacing the level check system?

I'll stay with the soapy mixtures until the system is completely unreliable

My black tank was always showing 2/3 full. I removed the lead at the tank and it still read 2/3 full. That told me the circuit board behind that black panel is where the problem was. It turned out that one of the four 14 pin Quad Comparator ICs on the circuit board was bad. I have know idea where or why I got it, but I had one in my spare IC bin. I have experience in electronic test equipment repair and calibration and knew how to replace it. It was a long shot, but fixed it. If you don't feel comfortable working with electronic, you can buy a replacement board. It should have a brand and model number someplace on it. I had to replace the one in my 5er, but don't remember how much it cost. All receipts went with it.

I absolutely am.

It's easy. U can use the existing wires. The panel is just slightly bigger than most factory panels, so u can use the existing holes. Be sure to get a second panel, then u wire first to the display panel in the wetbay, then upstairs. Install is a piece of cake for those of us who are mechanically inclined.
For those who are not, call me, bring the rig to me outside of chicago, and I will fix you up.

Our See Level sensor for the galley tank does not read properly. Have had it replaced once and new one does the same thing. The warranty guys said it had to do with the size of the galley tank, 32 gallons. We just live with it.

That's the best long term solution. Not the least expensive short term solution. A bottle of Pine Power or Pine Sol in the tank with about 1/2 tank of water, drive around awhile, the turns the better, then dump the tank. Fill the tank and dump again. That should clean it for quite awhle.
