Richmond tankless water heater will not clear error code

Why is it always Rheem problems?
Every water heater problem at fixya is Rheem.
And Rheem doesn't post any service manuals, like the other two big manufacturers, AO Smith-American, and Bradford White.

Rheem 2012 manual says if error 13 still displays, then contact installer or service technician. Mo Money buddy.
This is about oxygen sensor, poor combustion, bad venting, inadequate air supply, failed sensors, etc.
Get more fresh air to unit and see if that solves problem. The call service technician, and get out wallet.
Copy following link for Rheem-richmond tankless troubleshoot.

Maintain water heater according to instructions in manual to avoid common error codes. Of course this means you have to service the unit each month, and each year, without guarantee the thing will work correctly.

I want to send this back. I have had it for a year. Free tech support is a joke. 6 hours on the phone in one day and hung up on 4 times. Has anyone had any success getting a lemon law return success or is...

There should be a class action lawsuit.
Fixya is filled with unanswered questions about tankless water heaters
Manufacturers have protected themselves by limiting their warranty to installations done by people trained in that specific brand.
And then if you have a problem, the manufacturer refers you back to the installer.
If you install tankless yourself, there is no warranty if I understand the industry correctly.

Tankless promoters have not been crystal clear about the pitfalls.
The government has touted tankless as 'energy star' when that claim is dubious at best.
The internet is absolutely filled with promotion articles that claim high value of the product, without frank discussion of the pitfalls.
The savings and claims made by promoters has become a bit more tame over the past year or two, which implies that lawsuits are pending.
But if you read tankless promotion, they make dual and contradictory claims each time: They say the tankless will save energy, and provide endless hot water.
That is impossible with the barest of math because tankless use more energy per gallon of water heated, so if you consume endless hot water, the claim of energy savings is completely false.
Moreover, many promotions claim longer life for tankless units, yet the product is besieged with complaints, and the warranty papers do not reflect the promotion words.
I don't know what persuaded you to buy a tankless.
I believe there has been collusion and misrepresentation of the product.
Call some lawyers, but I suspect the industry is protected.

You cannot contact people asking questions, but you can certainly see the number of unanswered tankless questions each day.
