Customer Question
my rinnai v75ip has...
my rinnai v75ip has not been producing water at the correct temp, no matter how long I leave it on. I made sure all the dipswitches were correctly positioned, but hit a code 14 when accidentally moving dipswitch 5 on instead of 4 (in bank 2). Now I am unable to move the water temp above 120 (even though dipswitch 5 in bank one is on) and the water seems to be hammering a little--never did that before.
