MyAqua hot AHE-100-04s low tank level cut off light came on. I refilled the tank and  over flow tank the red light is still on and System is not working. I was wondering if you guys have any ideas on how to reset it the manual says it resets itself but that didn’t work?

 Thanks Don

I just went through this myself. Was it low on fluid? My sensor had broken off inside the tank. Just like a toilet float. On my coach I have pull 25amp fuse  and reinstall to reset. I believe you can connect both wires to check if the float is shutting down the Aqua hot. I know you can bypass the hi temp shutoff to check it

Thanks Paul it was the sensor. It got down to 27 last night but the heat pump’s kept us warm till I replaced it this morning. I’m on my way to Texas for the holidays so I need the Aqua hot.


You were lucky getting any heat out of your HP's at 27. Must be low humidity at your location.
