Your Bradford White water heater is a reliable workhorse, silently providing hot water day in and day out. But when it suddenly stops, a cold shower is a rude awakening. Often, the fix is simpler than you think: resetting the unit. This guide walks you through the exact steps, from locating that elusive button to knowing when it’s time to call for backup.
Before you start, having the right tools can make the job smoother. For many basic diagnostics and resets, a non-contact voltage tester and a simple multimeter are invaluable. Some homeowners and professionals also find value in a dedicated diagnostic tool like the EWH-00 Water Heater analyzer, which can help pinpoint electrical issues beyond a simple reset.
How Your Bradford White Water Heater’s Reset System Works
Think of the reset system as your water heater’s built-in circuit breaker. Its primary job is safety. When something goes wrong, it shuts off power to prevent damage or hazardous conditions. There are typically two key safety components involved in a trip.
The first is the high limit switch, often called the ECO (Energy Cut Off). This is the main reset button you’ll be looking for. It trips if the water temperature gets dangerously high, usually due to a faulty thermostat. The second is the operating thermostat itself, which may have its own smaller reset button. A trip here often points to a heating element issue in electric models.
Locating the Reset Button on Different Models
Where you find the button depends entirely on whether you have a gas or electric Bradford White unit. This is a key detail many guides gloss over.
- Gas Water Heaters: The reset system is part of the gas control valve. You’ll find a red button, often labeled “RESET,” on the valve assembly behind the lower access panel on the unit’s jacket.
- Electric Water Heaters: You have two access panelsone upper and one lower. Each covers a thermostat and heating element. The high limit switch reset button (usually red) is located on the upper thermostat. The lower thermostat may have a smaller reset button as well.
Pro Tip: Your specific series matters. For example, locating the panel on an MI series might differ slightly from a Defender series. Always check the manual for your model number first.
Step-by-Step Guide to the Bradford White Reset Procedure
Safety is non-negotiable. Before touching anything, turn off the power to the water heater at your home’s main circuit breaker panel. For gas models, turn the gas control knob to “PILOT” or “OFF.” Let the unit sit for at least 5 minutes to cool down.
For Electric Bradford White Water Heaters
- Power Down: Confirm the circuit breaker is OFF.
- Access the Panel: Remove the screw(s) securing the upper access panel and insulation block. Be careful not to tear the insulation.
- Find the Button: Locate the red reset button on the upper thermostat.
- Press the Button: Firmly press the button. You should feel or hear a faint click.
- Reassemble & Power: Replace the insulation and panel. Restore power at the breaker.
- Check Lower Thermostat: If the unit doesn’t fire up, repeat the process for the lower thermostat’s reset button.
For Gas Bradford White Water Heaters
- Gas & Power Off: Set the gas control knob to “PILOT.” Turn off any electronic ignition power source.
- Access the Valve: Remove the lower access panel to expose the gas control valve.
- Press the Reset: Find the red button on the valve and press it firmly.
- Relight the Pilot: Follow the lighting instructions printed on the label. This usually involves holding down the knob in “PILOT,” lighting it, then holding for 60 seconds before releasing.
- Turn On: Turn the knob to “ON.” Replace the access panel.

Troubleshooting Common Reset Issues
What if the reset button won’t stay in or trips again immediately? This signals an underlying problem the reset can’t fix.
- Bradford White water heater reset button not working: If the button won’t press or feels “dead,” the high limit switch itself may be faulty and need replacement.
- Why does my Bradford White water heater keep tripping? Chronic tripping points to a recurring fault. For electric heaters, a bad heating element or a sediment-shorted thermostat are common culprits. For gas, a failing gas control valve or a severely sediment-clogged tank causing overheating is likely.
- Diagnostic Lights: Some newer Bradford White models have LED diagnostic lights on the gas valve. A series of flashes is a fault codea goldmine for troubleshooting. Refer to your manual to decode it.

LP vs. Natural Gas Models
Here’s a critical missing entity: the fuel type. The reset procedure is identical for LP (propane) and Natural Gas models. However, the gas control valve is calibrated specifically for one fuel. Never interchange them. Using the wrong fuel creates a dangerous, sooty flame and can trip safety limits.
| Symptom | Likely Cause (Electric) | Likely Cause (Gas) |
|---|---|---|
| Reset trips immediately | Failed heating element, faulty thermostat | Failing gas control valve, severe sediment |
| No hot water, reset not tripped | Breaker tripped, wiring issue, failed thermostat | Pilot light out, thermocouple failure |
| Water not hot enough | One element failed, thermostat set too low | Undersized unit, gas pressure issue, sediment |
Safety First: When to Put the Tools Down
You can handle a basic Bradford White reset. But know your limits. Call a licensed professional immediately if you:
- Smell gas (rotten eggs) at any point. Leave the area and call the gas company.
- See water leaking from the tank itself (not from a pipe connection). This often means tank failure.
- Are uncomfortable relighting a pilot light or working with electrical components.
- Have performed the reset successfully, but the unit trips again within a day or two.
A professional has the tools to test components like the thermostat and high limit switch for proper function, which is safer and more accurate than guesswork. To understand why professionals often recommend the brand, see our analysis of how good Bradford White water heaters really are.
Preventative Maintenance to Avoid Future Resets
The best reset is the one you never have to perform. Regular maintenance is key.
For All Water Heaters
- Annual Flushing: Draining a few gallons from the tank removes sediment. This is the #1 cause of overheating and component failure.
- Temperature Check: Ensure your thermostat isn’t set above 120F (49C). Higher temps strain the system and increase high limit switch trips.
- Anode Rod Inspection: Check the sacrificial anode rod every 3-5 years. A depleted rod leads to rapid tank corrosion.
For Gas Models Specifically
- Keep the air intake and area around the unit clear of dust and debris.
- Listen for unusual noises during operation, like rumbling or whistling.
For Electric Models Specifically
- Periodically check that the circuit breaker connections are tight.
- Listen for sizzling or popping sounds from the elements, which indicate heavy sediment buildup.
A tripped Bradford White is usually a call for help, not a death sentence. Start with the simple reset. Listen to what the unit is telling you with repeated trips. Most importantly, respect the safety systems built into your appliance. They’re there for a reason. With this guide, you’re equipped to answer that call for help confidently, safely, and with the knowledge to decide when it’s a DIY fix and when it’s time for expert intervention.
