HWH leveling system

I once had a problem with the control panel with the lamps and switch attached. If I pushed down on the panel it would briefly come to life. I removed the cover panel with 4 screws and found the spring contacts between the panel and the circuit board below had lost contact. I stretched the springs slightly and reattached the panel. It's worked ever since.
On another trip I found another fuse hidden in the engine compartment. Good luck.
