Bradford White Electric Water Heater Not Heating
On this page (5 sections)
The Short Answer: Most Bradford White residential electric tanks have two elements, each with its own thermostat, plus a high-temperature limit on the upper thermostat. No hot water at all points to the breaker, the high limit, or the upper circuit. A short burst of hot that runs out points to the lower circuit. Check the breaker yourself. The rest is behind the electrical covers.
How a two-element tank heats
On a standard dual-element electric tank, the upper thermostat heats the top of the tank first. When the top is hot, it hands power to the lower thermostat and element. Only one element runs at a time. This is why the symptom tells you a lot:
| What you notice | Likely area | Urgency |
|---|---|---|
| No hot water at all, tank cool | Breaker, tripped high limit, upper element or upper thermostat | Soon. Check the breaker first |
| Hot for a few minutes, then cold, and slow to recover | Lower element or lower thermostat | Soon |
| Water lukewarm everywhere, tank seems hot | Mixing valve or crossover in the plumbing | See Bradford White not hot enough |
| No heat right after the tank was drained or newly installed | Element burned out because it was powered while empty | Leave the power off until checked |
| Breaker trips again straight away | Short in an element or the wiring | Leave it off and call an electrician |
| Water or rust at the element covers | Gasket or tank leak | See electric water heater leaking from bottom element |
What you can check
- The breaker. Most tanks use a double-pole breaker. If it has tripped, switch it fully off and then on, once. If it trips again, leave it off. That points to a short circuit, not a setting.
- Recent events. Was the tank drained, flushed or replaced recently? Was the power switched on before water was flowing from a hot tap? An element powered while dry fails almost at once. See water heater turned on without water.
- Whether every tap is affected. If one fixture is cold and others are hot, the problem is that fixture’s valve, not the heater.
- The rating plate. Note the model, serial number, voltage and wattage for the technician.
The high-limit reset button is on the upper thermostat, behind the access cover and insulation, next to live terminals. Resetting it means removing an electrical cover, so leave it to the electrician or plumber. A high limit trips because something overheated, such as a stuck thermostat or a grounded element. Pressing it again without finding the cause isn’t a repair. See why you keep having to reset your water heater.
What the technician will test
With power isolated and confirmed off, the technician checks each element for an open circuit or a short to the tank. They confirm each thermostat switches as the tank heats and cools, and look for scorched wires or terminals. They then confirm that both legs of 240-volt power reach the heater. Elements and thermostats are routine replacements. If one thermostat is discolored or melted, they’ll look for a loose connection that caused it. See what causes a water heater thermostat to burn up.
Repair or replace?
A failed element, thermostat or high limit is a part replacement. Consider replacement when the tank itself is leaking. It’s also worth considering when the heater is near the end of its expected life and has needed repeated element replacements, which often points to heavy sediment.
Frequently Asked Questions
Q: Why did both elements fail at the same time? A: Usually because the tank was powered while empty or only partly full, or because a single upper fault stopped all heating. If the upper element or thermostat fails, power never passes to the lower element. Testing shows which one actually failed.
Q: Does a Bradford White electric have a status light like some other brands? A: Standard Bradford White electric tanks don’t have the flashing diagnostic light some other brands use. Diagnosis is done with a meter by a qualified person. Heat-pump models such as AeroTherm have a display with their own codes.
Q: Should I turn the thermostat up? A: Not to diagnose a fault. If the tank used to reach your setting and no longer does, a part has failed. Raising the setting also increases the risk of scalding.
