Noritz NRCP 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. It is a fault in the mechanism that varies how much gas reaches the burner.

Noritz gives one remedy, a power cycle, and no second option. If it comes back, this is gas modulation hardware and not something to keep restarting past — an appliance that cannot control its gas rate accurately is one that should not be running.
