Learn about Rinnai Error Code 32, its meaning, causes, and solutions for water flow sensor faults.
Rinnai Error Code 32 indicates a fault with the water flow sensor, which may affect system performance. It is essential to diagnose the issue promptly to ensure proper operation.
To troubleshoot Error Code 32, check the water flow sensor for blockages or damage. Ensure all connections are secure and consider resetting the system if necessary.
The Rinnai unit triggers Error 32 when the water flow sensor detects an abnormal condition that prevents it from accurately measuring water flow. This could occur due to a high resistance in the sensor circuit, indicating potential issues with insulation resistance (RISO) or ground faults. The inverter may also trigger this fault if it detects that the sensor is not operating within the specified voltage range, which could be caused by wiring issues or power supply interruptions. The system relies on precise flow measurements to function correctly, and any discrepancies can lead to operational failures.
When encountering Rinnai Error 32, users may observe specific LED patterns on the unit indicating a fault. The display may show a flashing light or an error notification through the monitoring app. Additionally, there may be a noticeable drop in hot water supply, and the unit may fail to activate when hot water is requested.
Always consult a licensed electrician or certified solar installer when performing diagnostic or repair work on electrical systems to ensure safety and compliance with local codes.
To avoid future occurrences of Error 32, regularly inspect and maintain the water flow sensor and associated wiring. Ensure that the system is free from debris and that water flow is unobstructed. Schedule routine check-ups with a certified technician to keep firmware updated and to ensure the electrical connections remain secure and corrosion-free.
