What Does Rinnai Error Code 61 Mean?
If your Rinnai water heater displays error code 61, it means the fan motor has failed. The fan motor is responsible for circulating air around the heat exchanger, helping your water heater operate efficiently and safely. When the fan motor fails, the unit shuts down to prevent overheating and potential damage. This error code is specific to Rinnai water heaters and is not typically found in other brands.
Common Causes
- Most common cause: Worn out fan motor due to age or excessive use
- Second cause: Electrical issue, such as a blown fuse or faulty wiring
- Third cause: Obstruction in the venting system, preventing proper airflow
- Fourth cause: Incorrect fan motor installation or previous repair
