Getting ready to remove the J couch and peeked under there. Saw this and have no idea what it is. It is spring loaded seems like some kind of vent but have no idea for what, it is under the couch after all.

Level sensor
Hi Roland, that's your hwh leveling sensor.
Thanks for the replies Michelle and Doug. The darn thing is in the way for what I want to do. Time for the thinking cap.

It can be relocated to any horizontal surface, them calibrated using the three spring loaded screws. If the cable is long enough run it back to under the galley bottom drawer.
If that doesn't work into your plans, check with HWH, but I think it can even be mounted upside down on the ceiling of the basement.
If you remove it for any reason (to reposition it out of the way?), you will have to recalibrate it when you reinstall it. Not a big deal - simply requires getting the coach parked on a level service and sitting level. Then you adjust the 3 mounting screws until the yellow "out of level" lights on the HWH panel go out. The sensor should "float" on the springs - do not screw it down tight. The adjustment is pretty sensitive, so it can take a fine touch to get it "just right".
I seem to remember Kent Speers describing the difficulty of getting the sensor back to proper operation.
The adjustment is a PIA. The level sensor uses mercury switches so is a little touchy. There are 3 screws. You only adjust the left and rear screw. Only adjust one screw at a time and dump or add air enough so that the HWH has to go through it's leveling routine. Adjust again go off level and then adjust again. Use a level between each adjustment to check yourself. The hard part is deciding where to check level. Choices are floor, counter, or inside refrigerator.
see ya

Right Ken. That's kind of what Kent said but he was a bit more graphic, if I recall.
I adjusted mine by leveling the coach to my satisfaction with bubble levels. I then put the level system in manual mode and tweaked the sensor until the amber lights went out. It is an iterative process. There is a bit of hysteresis (the mercury doesn't move without some friction). With a good helper to watch the lights, you can get the sensor centered very well.
I did not test with the automatic leveling until after I had done the "adjust to the center of the 'amber lights out'" drill with HWH in the manual mode.
