Noritz NR98 & NR111 Code 32
Outlet thermistor fault. The outgoing water sensor is out of range, with the same three checks: resistance, open or short circuit, connection. This is the sensor the unit uses to hold your set temperature, and the one code 16 measures first. On the commercial ASME models in this range the outlet reading also gates code 21, the pressure switch, which does not exist on the residential units. Tell the technician which model you have before they start on a sensor.

Part replacementThe verdict
Replace a part
A failing outlet sensor shows up as water that swings rather than as no hot water. Cheap part, service call to fit it, worth doing promptly because the failure mode is unpleasant in a shower.
Typical cost: $120–$450
