How to fix Rinnai RL94 Tankless Water Heater - Error Code 10, again...

A follow-up to my 2018 video on how to fix my Rinnai RL94i that was producing an Error Code 10 while abruptly turning off heat during showers. I have since had to clean my exhaust fan cage three times now and this video is the latest time. Dead bugs sucked into the fan intake are the culprit most of the time, just like in this case. Just enough debris to overheat the heating chamber and make your shower cold. Hope this video saves your marriage like it did mine 🤣 Previous video at    • Rinnai Water Heater stops heating - Diagno...
