If your hot water stopped working suddenly, the first thing to check is the reset button. Many homeowners don’t even know it exists, but a quick press can bring the heater back to life. Below we’ll walk through when the reset button is useful, how to press it safely, and what to do if it trips again.
The reset button is a safety feature built into most electric water heaters. It trips when the heating element gets too hot or when there’s a short circuit. Common reasons it pops include a faulty thermostat, a build‑up of limescale, or a loose connection.
Typical signs that the button has tripped are:
If you notice any of these, turn off the power at the breaker, wait a minute, then try the reset.
1. Turn off the electricity. Find the circuit breaker that powers the water heater and flip it to the OFF position. This protects you from shock.
2. Locate the reset button. It’s a small red or black button on the thermostat housing, usually behind a removable panel on the top or side of the heater.
3. Press the button firmly. You should feel a click. If the button pops out immediately, something inside is still overheating.
4. Turn the power back on. Switch the breaker back to ON and wait a few minutes for the element to heat up.
5. Test the hot water. Open a hot tap and see if water reaches the desired temperature. If it does, you’re done.
If the button trips again within a few minutes, the heater likely has a deeper problem. In that case, call a qualified technician – trying to keep resetting can damage the unit.
While you’re waiting for a professional, you can do a few simple checks:
Regular maintenance helps prevent reset trips. Flushing the tank once a year removes limescale that builds up on the heating element. Also, test the temperature setting; keep it around 120°F (49°C) to avoid excess heat.
Remember, the reset button is a safety tool, not a permanent fix. If you find yourself pressing it often, schedule a service visit. A professional can check the thermostat, replace a worn element, or repair any electrical faults.
Bottom line: a quick reset can save you a cold shower, but repeated trips mean it’s time to call in the experts. Keep the breaker handy, follow the steps, and you’ll know exactly what to do the next time your water heater quits.
