I got this from day one. It's not a dirty part. Support have me the run around. Over 100 pictures of the exhaust and intake set up. More pictures at each level of support. After 80 hours of phone time with support I have up. A few months later I got a random person at rheem and he sent flame rods to me. I replaced them and it worked. For about a month. Then 13 again. I've had it apart so many times to check for a blockage because that's what they tell me. I seen a few people claim it's the gas control valve being plugged up and to take it apart to get any debris out. That's the last thing I have yet to try.

My outdoor Rheem tankless was flashing a code 13 so I why’ll I was in front of it I pulled the relief valve also known as TMP valve and noticed that after a second or two I smelt gas coming from the vent I am mediately knew that it did not light so I tested the coil and it was not giving any spark so it was not igniting sometimes a code 13 it’s something simple that doesn’t require a lot of looking or testing just simply knowing how the unit works is a big help

SOURCE: Paloma tank less water heater flashes code C4 13

I had the same problem with my Paloma a year and a half after installation...contacted Rheem customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.

How to repair code 13 for tankless water heater


Code 13 is probably Rheem, Richmond, Ruud, Paloma etc tankless.
Copy following link for troubleshoot resources:

Error 13 is oxygen depletion sensor
Imperfect combustion.
For example if tankless does not have required maintenance, then burner can get dirty and clogged.
This will cause unburned natural gas to rise inside hot flue pipe causing risk of explosion and fire, or in case of propane gas that is heavier than air, the gas will build up inside combustion chamber and cause explosion and fire.

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.
