Yesterday after dumping my tanks the hose reel stopped working. Did a quick check of the fuse panel and all looked ok. I stuffed the extended hose into compartment - it just fit. Later in day I had more time to look closer at the fuse panel. Turned out the 15A fuse for the hose reel was just loose - it wiggled in the socket.
It must have worked loose on some of the rough gravel and logging roads I was recently on driving up to my brothers cabin in northern Minnesota.
Lesson learned - check the fuse panel for loose fuses causing intermittent 12V
