My Rinnai hot water service is showing an ‘error 41’ code what does this mean?

A Rinnai error code 41 indicates that there is a fault occurring within the freeze protection sensor, only installed on outdoor Rinnai hot water systems. The freeze protection sensor is an electrical device that is needed to control the water temperature within your hot water unit.

How can I fix an ‘error 41’ code on my Rinnai hot water unit?

Fixing a faulty freeze protection sensor is quite difficult and usually requires assistance from a trained technician. However, there are a number of troubleshooting steps you can work through at home to identify and possibly even rectify the problem.

Firstly, check there are no loose or damaged wires leading to or from the sensor which may be interfering with its function.

Secondly, check the freeze sensor is not covered by insulation and is externally exposed, as this can cause incorrect functioning of the device.

Finally, if the freeze sensor can be removed from the unit, resistance readings will need to be checked to ensure that are set at the correct range.

If these troubleshooting steps seem too complicated, don’t stress, just call Metropolitan Plumbing on 1300 367 333 and we’ll get to the bottom of your hot water problems in no time.
