Hi,
I have a 2.5 year old Navien NPE-240A with an external recirculation device underneath my master bath sink (furthest fixture from the water heater), which would pretty much instantly provide hot water. I could hear the water recirculating every so often.
About a year ago, the recirculation stopped working so I had the installer come out and he couldn't figure it out so he had the Navien rep come to my house to try to figure it out. It was determined that the unit under my sink was not working properly so they replaced it and all was well.
About 3-4 months ago the same thing happened, so I bought the part online and installed it. Unfortunately it didn't solve the problem. I had a plumber come out who could not diagnose the issue, so I called Navien tech support who told me to check the dip switches, the Int & Ext valve and some of the settings. I did that and all seems ok.
What could be causing my recirculation to not be working properly? I'm stumped. Thanks for any advice.
