If you own or travel in an RV, you know how important hot water is for comfort—whether for showers, washing dishes, or simply cleaning up. The RV electric water heater switch location is a key detail that many new RV owners overlook, but it can make a big difference in how you use and manage your hot water supply. Finding, understanding, and using this switch properly can prevent cold showers, wasted energy, and even damage to your water heater. In this guide, we’ll look closely at where these switches are found, how they work, and what you should know to keep your RV’s hot water running smoothly.
Why The Water Heater Switch Location Matters
The electric water heater switch in your RV is more than just a button. Its location impacts convenience, safety, and efficiency. If you don’t know where the switch is, you might turn on the heater when the tank is empty, risking damage to the heating element. You may also waste power by leaving the switch on when you don’t need hot water. In some RVs, the switch is easy to find; in others, it’s hidden in a cabinet or outside the living area.
Many RVers make the mistake of only learning about the propane gas switch and forget about the electric one. But both are important, especially if your RV water heater has a dual heating system (electric and gas). Knowing the switch location can save you time and avoid costly repairs.
Common Types Of Rv Water Heaters
Understanding the kind of water heater your RV has helps you find the switch and use it correctly. There are three main types:
- Electric only: Uses electric power from shore or generator.
- Gas only: Runs on propane; often has a switch inside.
- Dual (Gas/Electric): Can use either electric or gas power.
Most modern RVs have dual water heaters, with separate switches for each power source. The electric switch is sometimes less obvious than the gas one.
Typical Switch Locations In Rvs
The location of the electric water heater switch varies by RV brand, model, and year. Here are the most common places you’ll find it:
1. Inside The Main Control Panel
Many RVs have a central control panel near the entry door or in the kitchen area. This panel may include switches for the water pump, holding tank heaters, generator, and both the gas and electric water heater. The electric switch is often labeled “Water Heater Electric” or just “Electric.”
2. In The Bathroom Or Kitchen Cabinet
Some RVs place the electric water heater switch inside a lower bathroom or kitchen cabinet. It may be near the sink or under the countertop. In these cases, the switch is usually simple—a black rocker or red toggle switch.
3. On The Water Heater Itself (exterior Access)
In certain models, the electric switch is located on the water heater’s outside housing. You’ll have to open the water heater access panel on the RV’s exterior (usually a small door). The switch is often small and may have a safety cover. This location is less convenient but reduces the chance of accidental activation.
4. Bedroom, Closet, Or Storage Area
A few RVs, especially larger ones, may hide the switch in a bedroom closet or storage compartment. This is less common but still found in some motorhomes and fifth wheels.
5. Multipurpose Switches
Some RVs use a multipurpose switch panel, where one switch may control both gas and electric operation, or be part of a touchscreen system. These are found mostly in newer, high-end models.
Examples Of Water Heater Switch Locations By Rv Brand
Let’s look at some real-world examples. This will help you see how RV manufacturers differ in switch placement.
| RV Brand/Model | Typical Electric Switch Location | Notes |
|---|---|---|
| Forest River | Main control panel near entry | Separate gas & electric switches |
| Winnebago | Bathroom cabinet or exterior panel | Older models use exterior switch |
| Jayco | Kitchen cabinet under sink | Labels vary by model |
| Keystone | Exterior water heater panel | Look for red rocker switch |
| Grand Design | Central utility panel | May be part of touch screen |
As you can see, there is no single standard. Always check your RV’s owner’s manual for the exact location.
How To Identify The Electric Water Heater Switch
Sometimes, multiple switches are grouped together, which can cause confusion. Here’s how to spot the right one:
- Look for labels like “Water Heater Electric” or “E/H” (Electric/Heater).
- The switch may be red, black, or illuminated.
- In exterior panels, the electric switch is often smaller and covered for safety.
It’s a good idea to test the switch with the water heater full of water (never dry!). Turn on the switch, wait a few minutes, and feel if the water gets warm.
How To Safely Use The Rv Electric Water Heater Switch
Using the switch is simple, but doing it the right way protects your heater and extends its life.
- Make sure the water tank is full. Never turn on the electric element if the tank is empty, or you’ll burn out the heating element.
- Flip the switch to “On.” Wait 20–30 minutes for water to heat (time depends on tank size).
- Turn the switch “Off” when not in use. This saves energy and reduces wear.
If you’re moving the RV or storing it, always turn the switch off.

Electric Vs. Gas Water Heater Switches
Many RVers wonder about the difference between the gas and electric switches. Here’s a quick comparison:
| Feature | Electric Switch | Gas Switch |
|---|---|---|
| Location | Interior panel, cabinet, or exterior heater | Usually interior panel |
| Power Source | Shore power or generator | Propane |
| Heat-up Time | Slower (20–40 min) | Faster (15–25 min) |
| Common Use | When plugged in at campground | When boondocking/off-grid |
Many RVers use both modes together for faster recovery, but you must know where both switches are.
The Hidden Switch: Exterior Panel Trap
One of the most common surprises for new RVers is that the electric water heater switch may be outside, behind the water heater access panel. This is often not mentioned by the dealer. Why do manufacturers do this?
- Prevents accidental use: You must really intend to use electric heating.
- Protects the element: Less likely to burn out due to mistakes.
- Meets safety codes: Some regions require the switch outside.
If your water heater isn’t working on electric, always check the exterior panel for a hidden switch. Even if you flip the interior switch, the electric element won’t turn on if the exterior switch is off.

Troubleshooting: Can’t Find Or Use The Switch
If you’ve looked everywhere and can’t find the electric water heater switch, try these steps:
- Check your owner’s manual. It should have diagrams or photos.
- Look inside every cabinet near the kitchen, bathroom, and entryway.
- Open the exterior water heater access door. Look for a small rocker switch—sometimes covered with a rubber or plastic flap.
- Search for a touchscreen or digital control panel. In luxury RVs, the switch may be hidden in the main system menu.
- Ask your dealer or check owner forums. Other owners of your RV model often post helpful photos or tips.
Sometimes, the switch is mislabeled or the label has worn off. If in doubt, trace the wiring from the water heater to the nearest switch.
What To Do If The Switch Fails
Switches can wear out or break, especially with heavy use. If the electric water heater switch doesn’t work:
- Test with a multimeter. Check for power at the switch and at the water heater.
- Inspect for loose wires or corrosion. Moisture inside cabinets or exterior panels can cause problems.
- Replace the switch. Most are standard 12V or 120V rocker switches, available at RV supply stores.
- Check for blown fuses or tripped breakers. The water heater circuit may be protected by a fuse or breaker in the main electrical panel.
If you’re not comfortable with electrical repairs, call a certified RV technician.
Upgrading Or Adding A Remote Switch
Some RVers find the exterior switch inconvenient and want an interior remote switch for easier access. This upgrade is possible but requires some basic wiring skills. Here’s what to consider:
- Buy a compatible switch kit. Kits are available for most water heater brands.
- Turn off all power before working.
- Run wires from the water heater to your chosen switch location. Use proper connectors and protect wires from damage.
- Label the new switch clearly to avoid confusion.
- Test carefully before closing up any panels.
This upgrade can make using your water heater much more convenient, especially in cold or wet weather.
Common Myths And Mistakes About Rv Electric Water Heater Switches
Many RVers (especially new owners) believe myths about water heater switches. Here are a few:
- Myth: “If I turn on both gas and electric, it will damage the heater.”
*Fact:* Most modern RV water heaters are designed for dual use. It actually heats water faster.
- Myth: “The electric switch is always inside the RV.”
*Fact:* Many are outside, sometimes hidden behind a panel.
- Myth: “Leaving the switch on all the time is safe.”
*Fact:* This wastes power and can shorten element life.
- Mistake: Turning on the switch before filling the tank.
*Result:* Burned-out heating element, expensive repair.
Safety Tips For Using The Electric Water Heater Switch
Staying safe is as important as staying comfortable. Here are practical safety tips:
- Always fill the tank first. Turn on a hot water faucet and let it run until water flows smoothly.
- Turn off when not in use. Especially before travel or storage.
- Check for leaks. Water near the switch or heater can be dangerous.
- Don’t overload circuits. If you’re running ACs, microwaves, and the water heater, you might trip a breaker.
- Teach all users. Anyone using the RV should know where the switch is and how to use it.
Saving Energy With Smart Switch Use
Electric water heaters draw a lot of power, often 1,200 to 1,500 watts. Used carelessly, they can quickly drain your RV’s batteries or overload your shore connection.
- Turn on the switch only when you need hot water.
- Use the “vacation” or “eco” mode if your heater has one.
- Consider adding a timer to the switch circuit for automatic shut-off.
Many RVers find they only need to heat water once or twice per day, not 24/7.

What If My Rv Has A Touchscreen Control System?
Some new RVs come with touchscreen panels (like the Lippert OneControl or Firefly). In these systems, the electric water heater switch is usually found in the “Water” or “Utilities” menu. If you can’t find it:
- Check the manual or online tutorials.
- Look for an icon showing a water heater or a lightning bolt.
- Remember, some touch panels require you to “wake up” the screen before the switch appears.
If the system is not working or the switch is “greyed out,” check the main circuit breakers and fuses.
Water Heater Switches And Rv Winterization
When winterizing your RV, you must turn off and drain the water heater. Don’t forget:
- Switch off the electric (and gas) switch.
- Let the heater cool before draining.
- Bypass the heater if adding RV antifreeze.
Missing these steps can result in burst tanks or damaged switches when spring comes.
Real-world Scenarios: How Switch Location Impacts Your Trip
Imagine arriving at a campground after a long drive. You hook up to shore power, flip the gas switch for hot water, but nothing happens on electric. After 30 minutes of cold showers, you realize the electric switch is outside, behind a locked panel.
If you had checked before leaving home, you’d have saved time and stress.
Or, you’re boondocking and accidentally leave the electric switch on. Your batteries drain overnight, and you wake up to a dead RV. Knowing how and when to use the switch is just as important as knowing where it is.
Comparing Popular Water Heater Brands
Different RV water heater brands use different switch layouts and wiring. Here’s a look at three popular brands:
| Brand | Switch Location | Notable Features |
|---|---|---|
| Suburban | Exterior panel (most models) | Manual reset, safety switch |
| Atwood/Dometic | Interior panel or kitchen cabinet | Some have dual-element controls |
| Girard (tankless) | Digital wall panel | Touchscreen control, no tank |
Always check your brand’s manual for the latest information.
