With your coach being made during the swap over time from the Grand Villa to the Unicoach the HWH main breaker could be hid. If you have the electric panel in the basement that hangs on the basement wall behind a fiberglass cover the main HWH main breaker will be hid in there. It will be one of the manual reset breakers. You may have a HWH memory fuse hid in the dash panel.

On my 95 Grand Villa (300) it was behind that fiberglass cover in the middle compartment that Mike referred to.

Also, the HWH control box with its internal fuses was in the first pass through compartment next to the generator fan housing (protrusion).

Thanks for the guidance gentlemen.
Found both panels. The HWH control panel is in a aluminum box in the first bay behind the generator. The panel with the fiberglass cover is in the next bay that has the slide out tray. All fuses are ok. Found other issues with the HWH. In travel mode the right side does not raise. When attempting to raise it manually, when pushing the raise button the left side raises with out pushing any other button. While holding the raise button no position button works. In one of the pictures I attached there is a white switch that was behind the fiberglass panel.
In the picture you can see a red indicator. When pushing the button directly below it the indicator will not appear. Push it again and it reappears. The indicator was  visible when I open the panel. Just wondering what it operates.

Rick,

That is a latching relay.  The little indicator is to tell you which position the switch is in. Like closed or open when you push the manual button .  At least it wasn't for the passenger side ejection seat.  This lets you have 2 switches operate one device from 2 different locations. With your coach being the year model it is this will operate either the water fill valve or water pump.

The ejection seat switch position could be handy 😊
