What Does Noritz Error Code 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.

Common Causes

  • Worn-out fan motor due to age and usage
  • Blockage in the ventilation system causing the motor to overheat and fail
  • Electrical issues, such as a blown fuse or faulty wiring, preventing the motor from receiving power
  • Incorrect installation or previous damage to the fan motor

Diagnostic Steps

If... Check Expected
You hear no sound coming from the fan motor when the system is running Measure the voltage at the fan motor's electrical terminals using a multimeter. Ensure the motor is disconnected from the power source before performing this test. 0 volts (open circuit) or voltage matching the system's power supply (short circuit)
The fan motor runs but doesn't spin Inspect the motor's shaft for any obstructions or signs of binding. Also, check the ventilation system for any blockages that could be preventing the motor from spinning. Motor shaft spins freely and ventilation system is clear
