I have HWH levelers on a 2021 Winnebago View, I am now getting a reading of excess slope (when it is definitely not). The jacks will level at times and at times give me the excess slope reading. I can manually level and I can manually drop the jacks to the ground then push the auto level button and they will level. Help please, trying to get to HWH is at least a 3-day wait.

Sounds like you may need to calibrate your leveling system. Not a complicated process, but it involves a systemic process. I have not personally calibrated my 2007 Itasca Ellipse, but did I climb under and watch the tech do it when we purchased the rig. I suspect you will get some detailed information on "how to" from other readers. If that is the problem, you can find a description of the process in HWH Service Manual on page 22 at https://www.hwhcorp.com/ml35963.pdf.
The post listed above discussing the pressure switch is most likely your issue. You need to identify which system you have.
I sent HWH an email asking about pressure switches for another issue. They sent me the part numbers and stated that the one pressure switch sole purpose is to trigger the Excess Slope light,
