I have a 2941DS Forester, and what I have learned is, that like nearly all black tank gauges, they are notoriously inaccurate. You most likely have a piece of toilet paper, (or other stuff) on the sensor. if you are going to a full hookup campground, put about 10 gl of water in the tank before you leave, by the time you get to the CG, it should have sloshed around enough to dislodge the debris, when you dump, be sure to use LOTS of water, & don't dump until it's at least 3/4 full. If it's stuck on the Full reading, look down the hole, if you don't see it, it's probably not full. |
