To Next PageTo Next PageHow to fix ignition error on Noritz NRC71-OD-NG Water Heater?
If you're experiencing an ignition error with your Noritz Water Heater, first check if the gas valve is open. Then, try turning the unit off and on again by either unplugging it from the power source or using the power button on the optional remote controller. Open a hot water fixture, and then restore power to the unit. If the error doesn't reappear, the problem is resolved.
Why won't my Noritz Water Heater fire with low flow and high supply temperature?
If you are supplying a low flow of water to your Noritz Water Heater when the supply water temperature is too high, the unit will not fire because it will overheat the outlet water.
Why is there white smoke from my Noritz NRC71-OD-NG exhaust?
If you notice white smoke coming from the exhaust vent of your Noritz Water Heater on a cold day, don't worry. This is normal, as the white smoke is actually steam.
Why is the hot water from my Noritz NRC71-OD-NG cloudy?
If the hot water from your Noritz Water Heater appears turbid, this is harmless. The turbidity is due to small bubbles that appear as the air in the water is heated and depressurized rapidly to atmospheric pressure.
Why does the water from my Noritz NRC71-OD-NG look blue?
If the water from your Noritz Water Heater appears blue, it may be due to small traces of copper ion in the water. This is not a health concern.
