What does 61 mean?

The error code 61 on your Noritz water heater indicates a fan motor failure. The fan motor is responsible for circulating air over the heat exchanger to maintain safe operating temperatures. When the fan motor fails, the system automatically shuts down to prevent overheating and potential safety hazards. This error is common in Noritz water heaters due to their high-quality, long-lasting components, but eventually, wear and tear can cause the motor to fail.
