What does Rinnai Tankless Water Heater Error Code 10 mean?

An Error Code 10 on your Rinnai Tankless Water Heater usually means there’s a problem with the venting system. There may be debris blocking the vents or there could be an issue with how the vents were installed.

There are a few things you can do yourself to see if a simple solution will fix your Error Code 10 problem. If these options don’t work, it’s time to call a professional Rinnai tankless water heater expert at Full Stack Plumbing.

What to Do if Error Code 10 Shows Up on Your Rinnai Water Heater Readout

A morning of suddenly cold showers may send you running to check your Rinnai water heater. Your unit’s computer screen may show an error code, communicating to you that there’s a problem.

If an Error Code 10 appears, it could just be a glitch in the pc board (circuit board). You can try turning the water heater off for a short time and then back on. This might reset the readout back to normal and allow the hot water to flow again.

You should also check your ventilation system for any obvious obstructions. Bugs and other debris can sometimes be located and removed to restore the full operation of your tankless water heater.

Once you’ve tried these options with no success, you should call the skilled Rinnai water heater professionals at Full Stack Plumbing. Going any further with self-repairs can void your manufacturer’s warranty. And if you don’t have plumbing experience, you could do more damage or even get yourself hurt.

Rinnai Tankless Water Heater Error Code 10 Issues

Your Full Stack Plumbing expert checks several potential issues for you.

An Error 10 Code often flashes when there’s something wrong with the ventilation system running from a Rinnai tankless water heater. But there are other reasons you might see this error message.

These are a few of the most common issues that can cause a tankless water heater to shut down:

Ventilation System Blockage – Debris can build in vent/intake pipes. Build-up can also affect a burner manifold.
Venting Improper Installation – Venting ducts may not fit together the right way. Sealant may have been used improperly.
Circuit Board Malfunction — A problem with the circuit board that runs the water heater could be faulty. A dip switch may be left on the wrong setting.
Improper Manifold Settings – Manifolds can regulate the amount of gas or water that flows in or out of your tankless unit. A problem can lead to a system shutdown and an error code.
