Rinnai Error Code 31

Rinnai Error Code 31 Troubleshooting

You may be wondering what a Rinnai error code 31 means?

The Rinnai hot water error code 31 signifies that there is a problem in relation to the gas burner thermocouple. The thermocouple is an important safety sensor within the gas tankless hot water heater which measures temperature. The purpose of the burner thermocouple is to prevent explosions and the dangerous release of natural gas. If there is a fault in relation to the burner thermocouple your hot water pilot light may not light at all or the burner won’t stay lit, which will result in no hot water for you.

Rinnai Error Code 31 Repairs

A Rinnai hot water fault code 31 will require a service call to resolve the issue. At Jim’s Plumbing, our plumbing professionals understand all Rinnai fault codes and how to quickly provide a resolution for the issues at an affordable cost to you, with quality workmanship guaranteed.

When it comes to a Rinnai error code 31, your attending plumber from Jim’s will check the fire manifold and gas pressures of your tankless hot water heater. The dip switches will be verified for proper position settings.

If all seems to be in correct order, the next step will be to replace the burner thermocouple which will rectify the code 31.

So quick!

Jayden was sent to fix my washing machine taps. He was polite and friendly, and explained what needed to be done. It was a bit more expensive than I expected, but from my call for service to the job being completed was only two hours. I would definitely recommend!
Laura M., VIC 5 stars rating

Laurence did a super efficient job
