Question about Water Water Heaters
12 - Flame Failure or Poor Ground
1. Immediate code 12 is usually a defective gas valve, power supply problem, or defective fan motor wiring harness.
2. If code 12 occurs after a few seconds it indicates that proper operation was established, but then stopped unexpectedly.
3. Verify that fuel is being supplied to the unit.
4. Check for proper electrical ground. Unit must use a grounded power supply.
5. Check for flue blockage on inlet or exhaust.

did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

error code 21 is malfunction of air intake filter switch. You need to check and make sure the air filter door is properly seated and that the front panel is properly installed

I just had the same problem and I fixed it in about an hour or 2.
First shut off the gas,water and power(unplug it)
Take off the cover
There are about 20 screws above the electrical circuit board.
You have to remove all of those screws to remove plate that is covering the burner assembly.
The burner assembly has these 3 pins that look like number 7's
these are covered with build up and gas can't flow right.
That's why you get the c211 error not enough gas.
Take a wire brush and gently remove any build up,
I also cleaned the thermocoupler which is next to the burners.
It looks like a metal pin with a couple of wires coming out of it this was also very dirty.
I took a can of air and basically freshened it up
It works perfect now.

All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

If you look on the left hand side of the burner control module you'll see 4 capacitors - the capacitors have most likely failed...pretty sure anything code 76 is P/S failure. It may also be covered for manufactures defects. If the cap is blown..the top will be slightly raised as apposed to flat like the other nearby caps - they are called top blow capacitors...the damage should be evident.
