2023 Elite II with Truma A/C, Truma on-demand hot water heater and Furnace, Isotherm frig. Setting uo at campsite once shorepower was connected the Truma Control Panel showed Alert diamond in center at bottom control panel. When selected the code read W255 W. The manuals provided on flashdrive to not list this error code. A/C would not come on when selected. Anyone have full listing of error codes. I think it is associated with power rocker switch behind exterior access panel for on-demand water heater which we were instructed to turn OFF when preparing to leave for next camping location.
