Anyone know where the power source is for the Webasto diesel heater is located in a 2020 R23 ? My controller for the furnace now speaks spanish(?) and won't turn on. I think I need to turn off power to reset it and hopefully get some heat back in the cabin 🙂

If there is a different solution, any advice is appreciated.

My research on Tug Nuts showed the fuse was located in the fuse panel near the door in the small mid-berth. I don't see anything labeled for the heater there (see photo of fuse panel) I've tried turning off the disconnects for both house and engine batteries but the Webasto controller doesn't flinch and still shows the same message. The red lights that are usually on when the heater is on are off.

This happened when the refrigerator was on and "someone" forgot to turn on shore power and the house batteries were dead dead a few days later. Turned on shore power and let everything sit overnight and Voila! Everything was back except for the heater.

Here are a couple of photos showing the controller and berth fuse panel.

Thanks for the help in advance,
