Welcome to iRV2 and Alpine Coach!

You mentioned that you shut the system down but here's some basic info. The HWH system MUST have both main shut-offs (Engine & House) turned "ON". The ignition switch MUST be in either "RUN (Right)" or "ACCESSORY (Left)" positions for the HWH control panel to operate.

Once you get the jacks to go down and level, keep in mind that "Store" function includes a timeout and will shutoff in 10 - minutes or so. Even if the green "Travel" light is on, you need to wait for the system to turn off automatically. If not, the hydraulic pressure won't completely equalize and the DS rear jack will undoubtedly drop on you at some point (probably while driving) and set off the "Jacks Down" alarm. Very annoying alarm but we've all probably had it happen at some point.

There is a small panel about 1' square rearwards of the front wheel on the passenger side. This is where the HWH hydraulic pump, solenoids etc. is located. The fuses are in the wiring harness. The clicking sound is the solenoid operating. If you don't here the pump it usually means you have lost 12v from the house battery, in my case probably because I forgot to turn the master switch by the entry door on. It is a little confusing as part of the system runs off the chassis battery and the rest off the house battery.
