I called Noritz error code 16 is a overheat problem. Noritz say's to flush your coil with vinegar or CLR.
Use a small pump to recirculate the CLR or vinegar through the system for 45 minutes and flush with fresh water. This worked for me.

Check your water pressure and the diagnostic codes on the controller to see if there is computer failure or another problem with the unit. send me an e mail i might be able to help im a nortiz certified service tech [email protected]

The trick with these hot water heaters is to keep the filter screen clean and flush the system with CLR periodically. Code 11 is ignition error. Is your gas valve turned on?

This means the thermal fuse has broken and needs replacement. The thermal fuse is a white cord which wraps around the heat exchanger. It typically breaks if the unit is excessively dirty and sooted. Before the fuse is replaced you should make sure the unit is cleaned with compressed air and descaled.

Hi,
The problem may be the flame sensor or the control.....
Check that the flame sensor is clean and also that there is a good ground from the burner to the control....make sure that the wiring to the unit is correct polarity, and then the ground is hooked properly also...
Is it flashing a code and if so, check what the code means....
