We cannot get our hot water system to work. When we turn on hot water the panel on the wall shows the fan going and you can hear that. You can hear a clicking noise inside the box. Then we get the E1 code. We are at a loss on what to do. Have arrived at Tybee Island just yesterday evening Friday, 12 August. If anyone could give us some information we would greatly appreciate it. This is our first outing with our new Jayco C class.
