Rinnai Hot Water Fault or Error Code 71

Rinnai Continuous Flow Hot Water Heater Fault or Error Code 71 Troubleshooting Guide

If you have one of Australia’s favourite continuous flow hot water heaters installed from the leading hot water manufacturers from Rinnai then you will notice that your Infinity hot water system features a self-diagnostic tool.

If there is a fault with your hot water heater a code will flash on the digital or status monitor allowing the fault to quickly and easily be diagnosed and repaired.

One of the error codes that you may come across is the Rinnai fault code 71. Fault code 71 indicates that there is a failure in relation to the systems micro-processor.

The micro-processor monitors and adjusts the output water temperature along with the water flow rate as required.

A Rinnai error code 71 on your tankless hot water heater will require a service call as this needs to be repaired by a fully qualified professional.

With all Rinnai fault codes you can try to eliminate the error code yourself by simply pushing the units on/off button to off and then on and also by turning the hot water tap off and then on.

This may clear the code if it was showing in error for any reason. But if the Rinnai fault code remains or returns then your Infinity continuous flow hot water system will require a repair as soon as possible.

Rinnai error code 71 repair

The Rinnai fault code 71 will be required to be investigated by a qualified technician due to the tankless hot water systems cover plate needing to be removed, exposing high voltage wiring.

The systems wiring harnesses will be checked for any bad connections from the gas valve solenoids back to the PC board.

Your attending technician will also check for any moisture within the system in relation to the combustion box and gas valve and will investigate that there are no leaks present regarding the heat exchanger.

If any issues are found in relation to these items any problem parts will be replaced as required. If the Rinnai error code 71 remains then either the gas control valve or the PC board will be replaced.
