Hi- I have a Navien Tankless Water Heater NR-240a. I have been having periodic problems with it the last month or so. Had no hot water, got error code 012 - cleaned water filter screens and it corrected. It did it again a few days later, had it flushed professionally and it corrected. It did it again within a week - cleaned water filter screens and it corrected.
Now, this a.m., got error 38 flow sensor (which has changed to error 012 again). Does anyone know how to get to the Navien flow sensor to inspect/clean it? I understand that it can get dirt/grit/slime on its "propeller".
Thank you in advance.
