Nice video! I had a question about my Navien tankless. In the last month the system would not provide hot water and the flame indicator on the front panel would turn off. This happens intermittently and rebooting the system will fix it temporarily until it happens again. Any idea why this may be happening?
What's the last time you had a professionally serviced? I think I would want to know that before I give any advice because there could be so many reasons why. Also how old is the unit?
