My Rinnai tankless water heater would sometime stopped producing hot water and it would not produce any error code. This video will cover the steps you can take to reset your water heater. Hopefully, one of this step will help fix your problem.

The common issue with this type of problem is that the water servo and sensor would not sense the water coming in. Either the sensor is about to give or there could be a clog that is preventing the turbine at the water entry to spin. If it is a clog, you simply need to clean it and you are good to go for a long time. If the problem is with the sensor intermittently stopping to recognize the heater, you will need to reset it and eventually you will need to replace it to fix the problem for good.

My issue begins with a clog but after 5 years, the problem is happening more often so I assume that I will need to replace the sensor really soon. I am looking around and the part that I need is out of stock. Hopefully, they will get this back in stock so I can replace it and share another video on how to replace the sensor.
