How much the answer changes between series
This is the part that catches people out. Code Er44 does not lead to the same job on every Noritz series: a replacement part and clear it yourself are both documented answers to this number, depending on the generation. Buying a part because a page for a different series said so is how this fault gets expensive.
The cost is documented the same way across all 2 series: $0–$900, depending on which of the manufacturer's causes turns out to be yours.
