Everything You Need to Know About Resetting Your Water Heater

Waking up to a lack of hot water is a jarring and unpleasant start to anyone’s day. But before you bid your morning routine farewell, wait. There’s actually a simple solution that’s likely right at your fingertips: resetting your water heater. Let's dive in.

Understanding Water Heater Reset

Why Water Heaters Need to Be Reset

Water heaters, like any other electrical appliance in your home, are not immune to issues. Power surges, system overloads, or a malfunctioning thermostat can trip the high limit switch, commonly known as the reset button. This is a safety mechanism designed to prevent overheating, but it can leave you in the cold.

Signs Your Water Heater Needs a Reset

Your water heater might be signaling for a reset if:

  • The water goes cold suddenly and unexpectedly.
  • Water temperature is inconsistent, swinging from hot to scalding without adjustments.
  • Your unit’s panel displays error codes (for models equipped with digital diagnostics).


Types of Water Heaters and Reset Procedures

Electric Water Heater Reset

For electric models, ensure the power supply to the heater is off before attempting any work, for safety. Then, locate the reset button, often hidden behind an insulation pad and a panel. Press the button firmly; if it clicks, you’ve successfully reset the circuit. Restore power and listen for the heating element to kick in.

Gas Water Heater Reset

For gas models, start by turning off the gas supply and waiting a few minutes to ensure there’s no residual gas in the lines. Relight the pilot light following the manufacturer’s instructions, then restart the gas supply and adjust the thermostat to your desired setting.

Safety Precautions Before Resetting

Importance of Safety First

Before you attempt to reset your water heater, it’s critical to ensure that your environment is safe. For gas water heaters, be alert for the smell of rotten eggs, a hissing sound near the gas lines, or dead vegetation around the gas line outside—these can all be signs of a gas leak. If you have an electric water heater, some signs of an electrical issue might include a tripped circuit breaker, a burning smell from the heater area, or visible frayed wires. These conditions can be hazardous and should get immediate attention from a professional.

When to Call a Professional

If you encounter any of these warning signs or if your water heater repeatedly requires resetting, it’s a signal that a deeper issue may be at play. In such cases, reaching out to a seasoned plumbing service like Black Lake Plumbing isn’t just a matter of convenience—it can be imperative for your safety.

How Long Should You Have to Wait For Hot Water?

Patience is key after a reset. It typically takes 30-60 minutes for the water to heat up, but this can vary based on tank size and unit efficiency. If hot water doesn’t return within this timeframe, consider checking for a tripped circuit breaker, malfunctioning heating elements, or incorrect thermostat settings.

Maintenance to Prevent Future Resets

Regular Water Heater Check-ups

Annual inspections can preempt the need for resets. Look out for sediment buildup, faulty heating elements, and wear on electrical connections.

When to Upgrade or Replace

Water heaters typically have a lifespan of 8-12 years. Some of the best indicators that it’s time for an upgrade include:

  • Frequent Repairs: Needing multiple fixes in a short period.
  • Rust and Corrosion: Visible rust on the tank or in your water.
  • Inefficiency: Rising energy bills with normal usage.
  • Leaks: Persistent moisture or pooling water around the base of your unit.


Understanding Error Codes and Alerts

Modern water heaters come equipped with diagnostic tools that provide error codes. Familiarizing yourself with these codes can assist in troubleshooting and help you decide whether you want to try and address the issue, or if professional service is the way to go.

Knowing how to reset your water heater is a valuable skill, saving you from unnecessary professional calls and ensuring your comfort. Remember, safety comes first, and when in doubt, professional help is just a call away.
