Identifying the Gas Valve

Locate the gas valve on your Rheem water heater. It is typically a brass or black knob or lever connected to the gas line. The valve may have a pilot light or an igniter nearby.

Resetting the Gas Valve

1. Manual Reset Button

Some Rheem water heaters have a manual reset button on the gas valve. Simply press and hold the button until you hear a click. This will reset the valve and allow gas to flow again.

If your water heater has a pilot light, it may have gone out. To reset it, follow these steps:

• Locate the pilot light assembly and turn the gas valve to the “Pilot” position.
• Hold a lighter or match to the pilot light hole and ignite the flame.
• Keep the gas valve in the “Pilot” position for about 30 seconds, then slowly turn it to the “On” position.

3. Igniter Reset

If your water heater has an igniter, it may have malfunctioned. To reset it:

• Remove the igniter from the water heater.
• Check the igniter for any dirt or debris and clean it if necessary.

4. Replace the Gas Valve

If the above steps do not resolve the issue, you may need to replace the gas valve. This is a more complex repair that requires the assistance of a qualified technician.

Troubleshooting Tips

• If you cannot ignite the pilot light, check for a clogged gas line or a faulty thermocouple.
