Rinnai Continuous Flow Hot Water Heater Fault or Error Code 58 Troubleshooting Guide
Is there a fault with your Rinnai hot water heater? Do you suddenly have no hot water? Your Rinnai continuous flow hot water system will display a flashing code on the hot water temperature controller as a self-diagnostic tool to allow for a prompt repair.
One of the Rinnai hot water error codes that may be displayed is fault code 58.
What does a Rinnai fault code 58 signify?
If an error code 58 is flashing on your digital monitor this indicates a scale build-up inside the secondary heat exchanger which, in turn, is causing a fault with the secondary heat exchanger sensor within the unit.
Some of the Rinnai tankless hot water heater models have a secondary heat exchanger installed.
The purpose of a secondary heat exchanger is to pre-heat your water using heat from the exhaust gases. These hot water heater models are extremely energy efficient.
Can I troubleshoot a Rinnai hot water error code 58 myself?
Unless the fault code 58 is showing in error, you will need to book the services of a fully qualified professional to rectify the Rinnai error code 58.
If you turn the hot water tap on and off as well as pushing the on/off button on your status monitor this may clear the fault code 58, if it was showing in error. If the code remains, or is removed but then returns again, then a service call will be required to resolve the issue.
