Rheem Water Heater Error Code 12
Error code 12 indicates a problem with the temperature sensor in your Rheem water heater. This issue leads to incorrect temperature readings, which can cause your water heater to stop functioning properly.
What Does Error Code 12 Indicate?
Error code 12 specifically points to a faulty temperature sensor. The temperature sensor monitors the water temperature within the tank. When it fails, the heater cannot accurately adjust or maintain the desired temperature. As a result, you’re likely to experience fluctuating hot water availability or completely cold water when you need it.
Possible Causes of Error Code 12
Several factors can cause error code 12:
- Faulty Temperature Sensor: The sensor itself may be damaged or malfunctioning.
- Wiring Issues: Damaged wires or poor connections can lead to incorrect readings from the temperature sensor.
- Sediment Buildup: Excessive sediment can interfere with the sensor’s function, impacting temperature readings.
- Age of the Unit: Older units may have worn-out components, increasing the likelihood of sensor failure.
- Electrical Problems: Issues within the electrical system, such as voltage fluctuations, can affect sensor performance.
Recognizing and addressing these causes promptly can help restore your water heater’s efficiency, preventing further inconvenience and repair costs.
