Rinnai Error Code 51

Rinnai Error Code 51 Causes

Are you having an issue with your tankless hot water heater? Is your Rinnai system flashing error code 51 and not producing adequate hot water? Sounds like you need a professional hot water plumber on the job!

When your Rinnai hot water unit shows error code 51, it means that there is an issue with the system’s inlet water temperature sensor. An issue with your inlet sensor can mean that your hot water heater produces fluctuating hot water because your unit is unable to regulate and control internal water temperature.

Rinnai Error Code 51 First Steps

When your Rinnai hot water system is displaying error code 51, your immediate steps should be to as follows:

• Firstly, turn your unit off
• Wait one minute
• Next, turn it back on again
• This will reset the unit’s self-diagnostic tool and preclude the possibility of your error code being, in fact, an error itself

If Your Rinnai Error Code 51 Persists

If your unit is still displaying the error code, follow the below steps to ensure that your unit is safe and will not blow up.

• Firstly, turn off the hot water supply
• Turn off the hot water heater’s power supply
• Turn off the gas and water supply valve to ensure there are no leakages
• Contact a qualified technician
