Hi,

2007 Bailey Pageant, water heater blows the fuse (5am household style) when first turned on, then is fine for the rest of the holiday - providing hot water as required. Any ideas? - the heater is always bled throughly prior to use and I would expect a blown
element to continue to blow the fuse?? Confused...
