Hot Water Heater

We have a 2015 27FB FC which has 2 switches for hot water. My question - does the electric switch just used to ignite the propane or if both switches are on is the water being heated by both propane & electricity?

No, the switch for the electric function on the water heater heats the water The switch for with shore power and does not use any LP gas. The switch for the gas function heats the water with gas only. When both switches are on, the water is being heated by both.

The electric switch operates the heater on electricity when you are connected to shore power. The other operates it on propane. You can use both if you are in a hurry for hot water. I'll use the campground's electricity if I can rather than burning my propane.

Please remember, NEVER switch the electricity ON with the water heater tank empty... the heating element will fail almost instantly. In other words, use the "electricity" option ONLY with a full water heater tank.

How do you know when the water heater tank is full?

Open a hot water tap at the sink and let it run until there is no air coming out. If there is air in the tank it will spit and hiss and splatter water until the water heater is full of water and all air is out of the line. After that you will get a nice stream of water. I like to open the hot water tap on the bathroom sink as well to bleed any air out of that line before turning on the heater. This us usually an issue for me in the spring when I am getting the trailer back in service for for camping season. Once you get all the air out, you should not have to any problems until you drain the tank again.

Pretty sure we have been doing things wrong. As soon as I disconnect & get the water hooked up we have been turning both propane & electric switches on without bleeding air out of the line. The last time out tried to use just electric to heat the water & wasn’t heating at all. Guess that means the heating element is shot. How hard & how do I replace the heating element?
