Rheem Water Heater Error Code 32: How to Fix It

Q: What causes Rheem error code 32?

Error code 32 is caused by a faulty outlet thermistor sensor that monitors hot water temperature. Common causes include thermistor failure due to age, corrosion from moisture exposure, loose wiring connections, or damage from overheating.

Q: Can I still use my water heater with error code 32?

While the water heater may continue to operate with error code 32, it's not recommended. Without proper temperature monitoring, the unit may overheat, provide inconsistent water temperatures, or shut down unexpectedly for safety reasons.

Q: How much does it cost to fix Rheem error code 32?

A replacement thermistor typically costs $15-40, making this an affordable DIY repair. Professional repair costs range from $150-300 including parts and labor, depending on your location and service provider.

Q: How often should thermistors be replaced?

Thermistors typically last 5-10 years under normal conditions. However, exposure to extreme temperatures, moisture, or electrical surges can cause premature failure. Regular maintenance and prompt repair of other issues can extend thermistor life.

Q: Will error code 32 reset itself?

Error code 32 will not reset itself as it indicates a hardware failure. The error will persist until the faulty thermistor is replaced and proper temperature readings are restored.

Abstract

Rheem water heater error code 32 indicates a faulty outlet thermistor, which is the temperature sensor that monitors hot water temperature at the tank outlet. This sensor helps regulate water heating cycles and protects against overheating. When it fails, your water heater can't accurately monitor outlet temperature, leading to inconsistent heating or safety shutdowns.
