What Does Richmond Error Code 16 Mean?
Error code 16 on your Richmond tankless water heater indicates a problem with the outlet temperature sensor. This sensor monitors the temperature of the water as it leaves the unit. The control board uses this information to regulate the burner and maintain the desired water temperature. If the sensor is faulty, sending incorrect readings, or if the wiring is damaged, the control board will display this error and shut down the unit as a safety measure. This prevents the water from overheating or the unit from operating inefficiently. Basically, the unit doesn't know how hot the water is, so it stops running to be safe. This error can also sometimes appear if the unit itself is overheating for other reasons, even if the sensor is still good. A technician will need to diagnose the root cause to get your hot water back.
Common Causes of Richmond Code 16
- Faulty outlet temperature sensor
- Loose or corroded wiring connections to the outlet temperature sensor
