Rheem Water Heater Error Code 61

Error code 61 on a Rheem water heater indicates a faulty blower motor condition. The control board has detected that the blower motor, which vents exhaust gases out of the unit, is not operating correctly. The heater shuts down as a safety measure to prevent dangerous combustion byproducts from entering the living space. A qualified technician should be contacted to diagnose and repair the issue.

Yes, this fault should be taken seriously. The blower motor is responsible for safely exhausting combustion gases, including carbon monoxide, out of the home. When the blower is not functioning properly, the heater shuts down to prevent unsafe conditions. Do not attempt to override or ignore this fault code, and ensure the unit remains off until a technician has inspected it.

A reset may temporarily clear the displayed fault, but if the underlying blower motor problem has not been corrected, the code will return once the unit attempts to operate again. Repeatedly resetting the unit without addressing the cause is not recommended, as it does not resolve the safety concern. The fault should be properly diagnosed and repaired before the heater is returned to normal service.

Rheem specifically recommends contacting a dealer or qualified service technician for this fault. Diagnosing code 61 involves testing electrical circuits, checking motor operation, and inspecting vent pathways, tasks that require proper tools and training. Because this fault is tied to combustion venting, improper repairs can create a carbon monoxide hazard. DIY inspection of the external vent termination for visible obstructions is reasonable, but internal repairs should be left to a professional.

Repair costs vary depending on the root cause. A simple wiring fix or vent clearing might fall in the range of $75 to $200 for a service visit. Replacing a blower motor assembly typically costs between $200 and $500 including parts and labor. Control board replacement, if needed, can range from $300 to $600 or more. Getting a diagnosis from a technician first is the best way to understand the specific cost for your situation.
