Noritz tankless water heater code 760
Remote controller communication fault. Code 760 means the same thing on all 5 Noritz series documented here — but the fix, and what it costs, is still worth reading for your exact unit.
What code 760 means on each Noritz series
| Series | What it means | Verdict | Typical cost |
|---|---|---|---|
| EZ Series & NCC199CDV | Remote controller communication fault | Part replacement | $0–$500 |
| NCC199 & NRC111 | Remote controller communication fault | Part replacement | $0–$500 |
| NR50, NR66 & NR71 | Remote controller communication fault | Part replacement | $0–$500 |
| NR98 & NR111 | Remote controller communication fault | Part replacement | $0–$500 |
| NRC Series | Remote controller communication fault | Part replacement | $0–$500 |
Each row opens the full page for that generation. We hold manuals for EZ Series & NCC199CDV, NCC199 & NRC111, NR50, NR66 & NR71, NR98 & NR111 and NRC Series, and each one gets its own reading of code 760 — what Noritz documents, what you can safely check yourself, and what the repair should cost.
What each manual actually says
The table above compares 5 series in four columns, which is enough to route you and not enough to explain anything. This is the Noritz wording behind each row, one entry per manual, so you can see where the 5 readings of code 760 agree and where they part company.
EZ Series & NCC199CDV — Remote controller communication fault
The remote controller and the circuit board have lost contact. Noritz checks the connection between them and looks for damage to the controller or the board. Note that Noritz prints this code without the "(F)" prefix that the rest of the table carries.
NCC199 & NRC111 — Remote controller communication fault
The remote controller and the circuit board have lost contact. Noritz checks the connection between them and looks for damage to either. Noritz notes that this code is not mentioned in the manual's troubleshooting flowchart.
NR50, NR66 & NR71 — Remote controller communication fault
The remote controller and the circuit board have lost contact. Noritz checks the connection between them and looks for damage to either, and notes that this code is not mentioned in the manual's flowchart. It has no flash-count equivalent for the obvious reason: it can only appear when a controller is fitted.
NR98 & NR111 — Remote controller communication fault
The remote controller and the circuit board have lost contact. Noritz checks the connection between them and looks for damage to either, and notes that this code is not mentioned in the manual's troubleshooting flowchart. There is no display window on this range to fall back on — where the NRC661 and NRC711 show a three-digit code on the board itself when the controller is out of contact, these units leave you with nothing to read. That makes a controller fault here more disabling than the same fault on the newer range.
NRC Series — Remote controller communication fault
The remote controller in the house and the circuit board in the heater have lost contact. Noritz checks the connection between them and looks for damage to the controller or the board. This is the one code in the table where the display window shows nothing at all — Noritz prints "No Display" in that column — because the fault is on the controller side.
Does it matter which Noritz you have?
EZ Series & NCC199CDV, NCC199 & NRC111, NR50, NR66 & NR71, NR98 & NR111 and NRC Series all route code 760 the same way: a replacement part, at $0–$500. That makes it one of the Noritz numbers you can act on before working out which unit you own.
What to check first, whatever your series
These checks are on the manufacturer's list for every Noritz series that reports code 760, so they are safe to work through before you have identified your exact unit. They also cost nothing.
- If it stays, book a service call.
That is 1 of the 3 checks documented for code 760. The rest differ by generation, so if none of those explains it, go to your own series above.
Which Noritz do you have?
On the 5 series that report code 760, the model number on the rating label starts EZ, NCC, GQ, N and NRC — match yours against the 43 listed below. You can also use the full model-number decoder.
