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.

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.

Rheem wants customers to call trained service technician since error codes are start-place for troubleshooting, and problems can be combination of issues.
Risk of CO poisoning from improper vent, or clogged drain line causing damage to heat exchanger, and risk of homeowner working on complicated gas-burning appliances are reasons why Rheem instruction manuals recommend yearly maintenance by trained technician.
That maintenance would typically cover most common error code issues, and homeowner could gather tips and information from service tech.
