RHEEM EEMAX & ECOSMART Flow Sensor Assembly FSA NFSML
Restore instant hot water with the OEM-style flow sensor your tankless heater depends on.
The EcoSmart FSA NFSML Flow Sensor Assembly is the genuine replacement flow sensor designed to bring your EcoSmart ECO 8 and ECO 11 electric tankless water heater back to peak performance. This sensor is crucial for your tankless water heater — it detects water flow and triggers the unit to activate, delivering hot water on demand. When your water heater stops heating or produces inconsistent temperatures, a worn flow sensor is often the culprit.
Wide Compatibility
Compatible with EcoSmart ECO 8 and ECO 11 tankless hot water heaters, as well as Eemax HomeAdvantage HA008240, HA011240, and HA013240; Eemax EEM24008, EEM24011, and EEM24013; Rheem RTEX-08, RTEX-11, and RTEX-13; and Richmond RMTEX-08, RMTEX-11, and RMTEX-13.
Key Features
- Replacement Part Number: FSA NFSML
- Instant Activation — The precision-engineered circuit board automatically senses water flow and activates the water heater’s heating element within seconds.
- Easy DIY Installation — Installs in minutes; equipped with a small propeller that must spin freely counter-clockwise to activate the heater.
- Quality Construction — Made from high-quality copper with a 15.35″ cable, 24AWG wiring, and cable temperature resistance up to 80°C.
- Durable & Long-Lasting — Built with high-quality materials for longevity and reliable performance, reducing the need for frequent replacements.
When to Replace Your Flow Sensor
When your water heater is no longer heating, or the temperature runs too low or too high, replacing the FSA NFSML flow sensor will keep your tankless water heater running properly and smoothly.
