Our Jacks will deplete the air when the system is activated, then quit.

ignition is on, Acc.,, brake set, ground is nearly level.

you push the ( ON/Auto ) the control panel will light, and the red light will illuminate, the air will dissipate. ( go to 0)
then the pump will not Start as usual. you can hear the solenoids click as usual. but no pump noise or pumping action.
key pad shows a yellow light on the pad.

Take a broom and move the level sensor under your Rv. Mine is located about center. On the last page of your manual. Mine got stuck with slush one time and cause all sort of issue. I put a deflector in front of it so maybe it would not happen again.

I don't believe we have that type of sensor

our 2000 coach has a sensor under the sink

to recap
our system will start when the HYD button is hit twice.
it will run until all air pressure is gone. ( it is supposed to stop when the pressure is 45 pounds)
when the all pressure is depleted the pump will not start
all the keypad buttons are active, you can hear the selenoids working when the buttons are pushed.
all cylinders are fully retracted (up)
all red lights are out, they usually light as soon as each cylinders start to extend

The HWH folks are useless they tell you there is a trouble call in,,but they never call

The one in the center is the one for the leveling indicators.
Jumper between the large posts on pump motor solenoid. See if pump starts.
If it does check the small posts for continuity.
