I don't see a service manual posted on internet.
Without a service manual showing ohm-readings for testing different parts, you are left guessing which part is problem.
Most water heater manuals today recommend yearly service to catch up on most causes for failure including air in fuel line, dirty or corroded burner parts, defective sensor, loose connection, etc.

SOURCE: how do I check the

1) Anode rod is located on top of water heater.
It is 1-1/6" hex head.
It might be under a plastic plug, or you might have to take off metal top of tank.
Sometimes you cannot remove anode rod because it is rusted too badly.
I have used impact wrench sometimes and been unable to budge them.

2) Open following links for anode illustrations and resources:

3) Rusty water implies that anode is bad.
But water released by TP valve implies overheating, or bad TP valve.

4) Replace TP valve.

5) Check your burner and combustion parts for orange-or-yellow flame and sooting on parts that implies the water heater needs to be cleaned. You do not want overheated combustion chamber to cause ECO event that might require new gas control thermostat.
Gas should burn with clear blue flame.

6) Overheating tank can also imply that gas control valve thermostat is not working correctly and may soon fail. This would be evidenced if water is very hot and new TP valve doesn't stop hot water release.

Look real close in area of where the back of it should be inside for a panel with screws, or one that will lift up. You may have to remove a few screws but access should be possible.
