Learn about Rinnai Error Code 65, its meaning, causes, and solutions for water flow control valve issues.
Rinnai Error Code 65 typically indicates a problem with the water flow control valve. This can lead to issues with water heating efficiency.
To troubleshoot Error Code 65, check the water flow control valve for blockages or malfunctions. Ensure that all connections are secure and functioning properly.
Error 65 is triggered when the inverter detects a fault with the water flow control valve. This can occur due to inadequate flow rate, which the system interprets as a potential safety hazard. The inverter uses input signals from flow sensors to determine whether the water is flowing correctly. If these signals fall outside acceptable parameters, such as during low flow conditions or if the valve is stuck, the inverter will shut down the heater to prevent damage or unsafe operation. This is part of the system's built-in safety protocols, which also monitor for electrical integrity and component function.
Upon experiencing Error 65, users may notice that the water heater fails to operate, accompanied by a blinking LED indicator on the unit's display panel. Additionally, monitoring apps may send alerts indicating a fault in water flow, and the unit may not respond to commands for heating water.
Always ensure that any diagnostic or repair work is performed by a licensed electrician or certified solar installer to comply with safety standards and local regulations.
To avoid future occurrences of Error 65, regularly maintain the water heater by checking for blockages in the water supply lines, ensuring that the water flow control valve is functioning correctly, and performing routine inspections of electrical connections. Additionally, consider scheduling annual maintenance with a certified technician to ensure all components are in optimal condition.
