C4wilson Posted August 25, 2014 Report Share Posted August 25, 2014 Trying to troubleshoot why i get the "RH NF" error (no flow or low flow to heater). Looking for any advice. I've tried cleaning the filters. No change, removed the filters temporarily and still go the error. Opened the PVC out of the heater and let out some air (I actually heard a bit come out) and then water came out. But still get the error. Any other suggestions? Thanks.
