On my 95 Scenic Cruiser, the Water heater power seems to come from the panel on my range hood, when it quit working, I lost my water pump and heater level sensors and vent fan. I replaced the fuse in 2009 so I am not sure if it was in my Battery Control Center or the Fuse Panel/Circuit Breaker Panel on my Bed Platform. At least, it gives you two places to look.
