Hello, Frazell -

If your A. O. Smith water heater is new, it probably came with an owner's manual. Find where you put yours and check the manual to find out what the ECC code means.

From an owner's manual for a particular A. O. Smith Hybrid Heat Pump Water Heater, the code ECC means the heat pump compressor is not functioning.

Hi Joyce,here's a link on your code 5d and what it means. ShopYourWay

The error is a HIGH LIMIT THERMAL ERROR. That means Calcium buildup has appeared in the unit. It is also called scale. To clear the error you have to power it off. That is done by the circuit breakers. You should descale the unit first though.

There is water leakage internally. Possible tank or water inlet or water entering from the combo air inlet/exhaust pipe.

Error code 36 does not show in any resource, including 2008 service manual, or 2012 product manual.
Check that remote control display is illustrating the correct number.
For example there is error code 35.

Error code means that you have electronic gas control valve.

Copy following link to identify gas control valve, read error code meanings for each, and download service manual relevant to each gas control, but not specifically Rheem since rheem does not post service manuals.

The fact that water heater restarts, means that water heater is getting gas, getting sufficient air for combustion, thermister is ok, gas pressure is good, etc.
The fact that you unplug and replug water heater and it works, shows that you have power vent model.
Since water heater worked correctly before, 2 flashes with Rheem power vent model could mean that pressure switch has failed.

code 11 means there is not enough gas

is this a new install?
do you have at least 3/4" gas line to the unit?

a 16 error code is typically caused by scale formation. I'd recommend performing a descale on the heater.

"Pres sw open" means there is insufficient air flow. either the vent if blocked, or the blower turns too slow/ or died.
