I have a 2006 Beaver Marquis. When I turn Aqua Hot on at switch in galley it comes on and starts to run normal. In a few seconds I hear a click in bathroom. When that click occurs the unit is turned off as if you had pushed the switch. In a couple seconds it clicks again and the amber light on switch comes back on just for a few seconds and and it keeps doing this several times and it will eventually stop and have to turn batteries off and unplug from shore power to reset. The unit does not fire up.
Aqua Hot thinks it is a multiplex problem. All help appreciated. Love the Forum.

There will no doubt be better suggestions to come but for now here is my 2 cents.
The AH will cut off due to power shortage so if the shore power is good and or the batteries are at 13.4V we can eliminate that.
The flame sensor comes to mind. If it is bad or the window too dirty the sensor reads no flame and will shut down the AH. When you first try to start up is there any exhaust? If yes then it is trying to burn. If no then it isnt lighting at all and I would suspect the computer / controll unit.
Please note the above post about AH problems and the ignition coil was replaced (due to no spark I guess).
Just some food for thought.
Good luck!
