If you own an RV, you know how important hot water is for daily comfort. The Suburban Advantage RV tank water heater is a popular choice for many campers because it offers reliability and solid performance. But, like any appliance, it can sometimes stop working or need a reset. Whether your water heater suddenly stops producing hot water, or you see an error light, knowing how to reset it can save you time and hassle. This guide will show you the clear steps to reset your Suburban Advantage RV tank water heater, explain why resets are sometimes needed, and offer tips to keep your heater running smoothly.
Understanding The Suburban Advantage Rv Tank Water Heater
Before jumping into the reset process, it helps to understand how your Suburban water heater works. Suburban heaters usually have a 6-gallon or 10-gallon tank and offer both gas and electric heating modes. There are safety features built in, like ECO (energy cut-off) and T-Stat (thermostat), to prevent overheating or unsafe operation.
You’ll usually find the water heater’s access panel on the outside of your RV. The reset button and wiring are inside, protected from the weather. When the heater senses a problem, it may shut down or display an error. Common signs include:
- No hot water when you turn on the tap
- A red fault light on your RV’s control panel
- Clicking sounds but no ignition
Knowing these basics makes it easier to diagnose problems and reset your unit when needed.
When Should You Reset Your Suburban Rv Water Heater?
Resetting isn’t something you do every day. In fact, if you find yourself needing to reset often, there may be a deeper issue. Here are the most common reasons you’ll need to reset:
- Overheating: If the water gets too hot, the ECO kicks in and shuts the system down.
- Power Issues: After a power surge or when switching between shore power and generator.
- Propane Problems: If there’s a brief interruption in propane, the heater might lock out.
- Faulty Thermostat: Sometimes the thermostat triggers a false shutoff.
- After Maintenance: Resetting is often required after replacing parts or draining the tank for winterizing.
A reset clears these faults and gives your water heater a fresh start.

Tools And Safety Precautions
You don’t need many tools to reset your water heater, but a few basics will help:
- Phillips or flathead screwdriver
- Work gloves
- Flashlight (if you are working in low light)
- Towel (for drips or condensation)
Important safety tip: Always turn off the power and propane supply before opening the water heater panel. Working on a live unit can be dangerous. Wait for the system to cool down to avoid burns.
Step-by-step: How To Reset A Suburban Advantage Rv Tank Water Heater
Resetting your Suburban heater is straightforward if you follow these steps. Here’s what you need to do:
1. Turn Off All Power And Propane
- Switch off the water heater at your RV’s main control panel.
- Set the propane supply to “off.”
- If you have an electric model, unplug your RV from shore power.
2. Locate The Water Heater Access Panel
- Go outside your RV and find the rectangular metal panel, usually labeled “Water Heater.”
- Use your screwdriver to open the panel.
- You’ll see the wiring, controls, and reset buttons inside.
3. Identify The Reset Buttons
Suburban models have two small reset buttons, usually covered with rubber:
- ECO (Energy Cut-Off) reset: Often marked with a red button.
- T-Stat (Thermostat) reset: Usually black.
Both are next to each other on a small control board.
4. Press The Reset Buttons
- Press the red ECO reset button firmly until you feel a click.
- Press the black T-Stat reset button the same way.
- You may need to use your fingernail or a non-metal tool to push them in.
5. Close The Access Panel
- Make sure you don’t pinch any wires.
- Tighten the screws securely to keep out water and dirt.
6. Restore Power And Propane
- Turn the propane back on.
- Switch the electric or gas water heater control inside your RV to “on.”
- Plug your RV back in if needed.
7. Test The Heater
- Wait 10-15 minutes for the tank to warm up.
- Turn on the hot water tap inside your RV.
- Check for hot water and listen for the burner or electric element.
If you hear the unit start and hot water returns, your reset was successful.
Table: Reset Button Locations By Model
Different Suburban Advantage models sometimes have slightly different layouts. Here’s a quick reference:
| Model | Reset Button Color | Location |
|---|---|---|
| SW6DE | Red & Black | Lower control board, under access panel |
| SW10DE | Red & Black | Middle right, behind foam insulation |
| SW12DEL | Red & Black | Upper left, next to wiring harness |
If you have trouble finding the buttons, check your owner’s manual for an exact diagram.
What If The Reset Doesn’t Work?
Sometimes, a reset won’t fix the problem. Here’s what you should check next:
- Power supply: Use a multimeter to make sure you’re getting 12V DC and 120V AC as needed.
- Propane flow: Confirm your tank isn’t empty and the gas valve is open.
- Bypass valve: Sometimes the water bypass is set wrong after winterizing.
- Burner tube origniter: Look for spider webs or soot that can block ignition.
If you’re not comfortable working with electricity or gas, contact a certified RV technician.
Common Mistakes To Avoid
Many RVers make simple mistakes when resetting their water heater:
- Forgetting to turn off power or gas before opening the panel (dangerous! ).
- Not pressing both reset buttons (some models require both).
- Not waiting long enough for the tank to heat up after the reset.
- Overlooking a tripped breaker or blown fuse in the RV’s main panel.
Catching these mistakes early can save you from frustration and possible damage to your heater.
Preventing Future Lockouts And Resets
A well-maintained water heater shouldn’t need frequent resets. Here’s how you can prevent lockouts:
- Flush the tank regularly: Sediment builds up and causes overheating.
- Check anode rod yearly: Replace if worn down.
- Inspect wiring: Look for loose or corroded connections.
- Keep propane lines clean: Dirt and insects can clog them.
- Winterize properly: Always drain the tank if storing your RV in cold weather.
Regular care makes resets much less likely.
Troubleshooting: Error Codes And What They Mean
Some Suburban water heaters have LED indicators or error codes. Knowing what these mean helps you decide if a reset is enough, or if you need repairs.
| Error Code/Indicator | Meaning | Action Needed |
|---|---|---|
| Red Light On | Lockout (failed ignition) | Reset water heater, check propane |
| No Light, No Heat | Power issue | Check fuse, reset breaker |
| Flashing Light | Thermostat or ECO tripped | Reset buttons, check for overheating |
If the code returns after a reset, deeper troubleshooting is needed.
How Long Does It Take For The Water To Heat After A Reset?
After a reset, the time it takes for hot water to return depends on your tank size and the energy source:
- 6-gallon tank (gas): About 20-30 minutes
- 10-gallon tank (electric): About 45-60 minutes
For best results, limit water use during this heating period. If you use a lot of hot water right away, you’ll get a burst of cold before the tank can recover.

Real-world Example: Resetting On The Road
Let’s say you’re camping in a remote spot and the hot water suddenly stops. You check the control panel and see a red light. You remember the reset process:
- Turn off power and propane.
- Open the access panel with your multi-tool.
- Press both reset buttons.
- Close the panel, restore power, and test.
In less than 10 minutes, you’re back in business. This simple process can save your camping trip.
Table: Gas Vs. Electric Heating Recovery Times
Many RVers wonder how gas and electric heating compare after a reset. Here’s a quick look:
| Tank Size | Gas Recovery Time | Electric Recovery Time |
|---|---|---|
| 6 gallons | 20-30 min | 45-60 min |
| 10 gallons | 30-45 min | 60-90 min |
Gas is usually faster. If you need hot water quickly, choose the gas mode.

When To Call A Professional
Most resets are easy, but certain problems require a technician:
- Frequent lockouts (more than once a month)
- Signs of leaks or corrosion
- Smell of gas near the heater
- Soot or black marks near the vent
Don’t risk safety. If you’re unsure, get help from a qualified RV service center.
Extra Tips For Reliable Hot Water
- Insulate your water lines in cold weather to prevent freezing.
- Don’t run the heater dry—always make sure there’s water in the tank before turning it on.
- Keep a spare anode rod in your RV tool kit.
- Label your access panel inside the door for quick resets in the future.
Many beginners forget to refill the tank after winterizing. Running the heater dry can damage the unit and void the warranty.
