Step-by-Step Instructions

1. Shut Off Gas and Water Supply

Begin by turning off the gas supply to the water heater. This is typically a valve located near the bottom of the unit. Next, turn off the water supply by closing the cold water inlet valve.

2. Disconnect Power

If your water heater is electric, disconnect it from the power source by turning off the circuit breaker or removing the fuse.

3. Remove Access Panel

Locate the access panel on the front of the water heater. Using a screwdriver, remove the screws holding the panel in place and carefully lift it off.

4. Locate the Thermostat

Once the access panel is removed, you will see the thermostat. It is typically a small, round device with a dial or digital display.

5. Reset the Thermostat

For Dial Thermostats: Turn the dial counterclockwise to the lowest temperature setting and then back clockwise to the desired temperature.

For Digital Thermostats: Press the “Reset” button or follow the manufacturer’s instructions for resetting the thermostat.

6. Reinstall Access Panel

Place the access panel back on the water heater and secure it with screws.

7. Turn On Gas and Water Supply

Turn on the gas supply valve and then open the cold water inlet valve.

8. Check for Leaks

Once the water heater is turned on, check for any leaks around the thermostat or other connections. If you notice any leaks, tighten the connections or call a plumber.
