Michael,
There is an HWH manual in Coach Assist that has a good troubleshooting section. The problem with both units is probably that the level sensing unit(s) are out of adjustment and telling the systems a level has been attained because it (they) are level, when the coach is not.
I think the sensing unit is located behind the dash and accessible by removing the top dash panel behind the instrument panel. There are adjustment screws to re-level the unit. Follow the instructions in the HWH manual. BE SURE the coach is level (use manual levels inside the coach) before starting the adjustment. Once the HWH system is corrected, check the IDS system as they may share the same sensor. If not, I seem to remember that the IDS sensor was located in the panel to the left of the driver, but don't hold me to it. In any case the procedure will be very similar: get the sensor level and see it that fixes the problem.
