How to Use the Water Heater Reset Button
If your hot water suddenly stops, the first thing to check is the reset button on the heater. Many people overlook it, but a quick press can bring heat back in minutes. Below we’ll explain what the button does, how to use it safely, and the signs that you need a professional.
What the Reset Button Actually Does
The reset button is a safety switch built into most electric water heaters. It trips when the heater gets too hot or when there’s an electrical fault. When it trips, the heater stops heating to protect itself from damage or fire. Pressing the button tells the unit that the problem is cleared and lets it try to heat again.
Step‑by‑Step Guide to Resetting
1. Turn off the power. Locate the circuit breaker for the water heater and flip it to ‘off’. This prevents any shock while you work.
2. Find the reset button. It’s usually a small red or black button on the side of the heater, near the thermostat. You may need to remove a plastic cover.
3. Press and hold. Push the button firmly for a couple of seconds. You should feel a click; that means the switch has reset.
4. Turn the power back on. Switch the breaker back to ‘on’ and wait a few minutes for the heater to start heating.
5. Check the hot water. Turn on a tap and see if warm water returns. If it does, you’re done. If not, the heater may have a deeper issue.
Remember, never force the button or use tools to pry it. If it won’t stay in, there’s likely a persistent fault that needs a qualified technician.
When to Call a Professional
Even if the reset works, the underlying cause might still be there. Call an expert if you notice any of these signs:
- Repeated trips of the reset button within a short time.
- Strange noises like popping or hissing from the tank.
- Water that’s discolored, smells bad, or leaks around the heater.
- Visible rust, corrosion, or a burnt odor near the wiring.
These clues often point to a bad heating element, a faulty thermostat, or a wiring issue. A pro can safely test the components, replace parts, and make sure the heater runs efficiently.
Preventive Tips to Keep the Reset Button From Tripping
Regular maintenance helps avoid future trips. Here are a few simple habits:
- Drain and flush the tank once a year to remove sediment that can overheat the element.
- Check the temperature setting; 120°F (49°C) is enough for most homes and reduces stress on the heater.
- Inspect the power connections for loose wires or signs of wear.
- Make sure the area around the heater stays dry and well‑ventilated.
By keeping the heater clean and set at a moderate temperature, you reduce the chance of the safety switch engaging.
