Noritz NRCP Eco TOUGH Code Er67
Gas modulation assembly fault. Noritz calls this AGM abnormality, and the wiring tables in the same manual identify the AGM as a stepper-motor assembly with position feedback on the gas side. The remedy is to try the main power switch off and on, and Noritz states the conclusion if that fails: still the same error code means AGM failure. Manual reset.

One free attempt, and then Noritz names the part outright. An appliance that cannot control its gas rate accurately is not one to keep restarting past, so treat a returning Er67 as a stop.
Typical cost: $0–$1,000

What you can safely check
Before anything else: if you smell gas, stop here, leave, and call your gas utility.
- Cut the power for a minute and restore it — Noritz's only listed remedy.
- If Er67 returns, leave the unit off and call a licensed professional. Noritz's own conclusion at that point is AGM failure.
