Find out the steps on how to start and turn on an electric water heater below.
Steps to Turn on Electric Water Heater in RV
Step 1: Ensure That The Freshwater Tank Is Full
Before turning on RV water heater, you have to make sure that your freshwater tank is full. If your tank is empty, fill it with water.
Find a water source near you and connect your hose. You can also use a water filter to ensure that the liquid is free of unwanted elements.
Once everything is hooked up, run the water hose to the panel containing the freshwater tank. Connect the hose and lock it in place, then let the water flow.
Step 2: Open The Pressure Relief Valve
Opening the pressure relief valve can do two things. First, it can ensure that the hot water tank is full. Second, it can release any air trapped inside the tank.
When you heat water repeatedly, air bubbles can form inside the hot water receptacle. You need to remove the air so that it won’t affect the efficiency of the heater unit.
The pressure relief valve is usually located on top of the water heater unit, so it’s easy to find in the access panel. To open, pull it to release the air out from the hot water tank. You should see some water coming out from the small plug or spigot.
Step 3: Find The Switch Location
The switch can be hard to find from the many components built into the water heater access panel. So, you need to open the panel to get a clear view of the switch. The location may also vary, depending on the unit.
Forest River has the switch located outside the RV near the water heater. Some water heaters have the switch located at the bottom corner, while others have it hidden at the back.
Step 4: Switch On Or Off
Once you’ve found the switch, turn it to the ON position. You should be connected to a 120-volt AC power source or generator to help kick-start the operation of the water heater.
Some water heaters like the Suburban SW6DEL model have another indoor switch to activate the heating element of the water heater. This comes in handy when it’s raining outside.
You can control the operation of the water heater in the RV as long as you leave the switch outside in the ON position.

Electric vs Propane RV Water Heater: Which is Better?
Propane water heaters are ideal for boondocking because you only need a propane tank to run the unit. However, you might need to use more propane to heat the water at a higher temperature, which can be a bit expensive in the long run.
Switch RV water heater from propane to electric if you want to avoid water temperature problems. Compared to gas models, a travel trailer electric water heater has a higher efficiency. All the heat goes to the heating elements and not condenses into the air.
More importantly, you don’t need to spend more on propane to run the water heater. All you need is a 120-volt AC power source, which you can find in campgrounds and on generators.
