First , do you have a dash HWH ''reset" button ?? Push and hold it with everything on. If not resetting you have to go under the driver in the first compartment to the "main" computer box for the leveling system and you can try playing with the 4 plugs for good connections and active lights. I experienced a cracked diode that made my entire system go down and it was a 15 cent part. It seems that you do NOT have a communication problem with your keypad and system since you get red then yellow lights in sequence. Your level sensor should be in the 3rd bay back on the drivers side toward the center on a ledge and has springs and a plate that should be level. Air is not moving into the system and check valves and solenoids could be worth pursuing... Randy @ HWH has always been really good with any problems I have had over the years, but does require patience for the initial call back, since they do one customer at a time on the "help" line. It took only 1 day for my last call back about a year ago and once they start with your problem they will take your calls right away until fully fixed. Newell has not been able to assist me with HWH problems the last 4 years, so I was forced to wait for the call back and the first time it was only a few hours...
