There is a digital, or status, monitor which will display an error code which tells you at a glance what the issue may be with the system.

This allows for a quick and easy repair to have your hot water back running hot once more.

One of the fault codes that you may see flashing on your systems monitor is a Rinnai error code 72.

The fault code 72 indicates that there is a problem with the unit’s micro-processor in relation to the flame sensing device. You can try to clear any Rinnai fault code yourself (if it has happened due to a trip in the system) by turning the hot water tap off and on and also the monitor button off and then on. If the fault code remains then a repair will be required.

One of the reasons that the flame sensor may become faulty is due to a dirt or debris build-up.

This can easily happen depending on where your hot water heater is located. You can avoid this issue by having your hot water heater serviced periodically as according to manufacturer’s instructions (usually once every two years).

If you do come across a Rinnai fault code 72 you will need to employ the services of a fully qualified technician to rectify the problem.

Attempting DIY repairs on a hot water heater if you are unqualified is extremely dangerous especially when you are dealing with gas and high voltage electrical wiring, and in many cases will cause more damage and cost in the long run.

Not to mention you will more than likely void your appliance warranty and could harm any related insurance claims that may be required in the future.
