Rheem, Richmond, Ruud, and Paloma are all the same manufacturer. After about 9 months, my tankless RTG-74PVN started giving me error code 11 and cold water!. I fixed it by cleaning the burner, as shown in this video:

I recently had a similar problem with my N-132M-ASME heater. The unit would come on, then shut down and flash Error Code 21. According to the owners manual, that code indicates the unit is not getting enough air. I tried vacuuming the unit, blowing it our with air and checking to be sure the exhaust lines were clear. Nothing helped. A service technician came out and recommended I descale the unit and clean the burner. I did this but the problem did not go away. He also suggested I replace the Burner Sensor. It's not an expensive part, around $20. I ordered the part and have not had a problem since I installed it. Hope this helps.

Check manuel for code

Sorry to read about your problem, I hope this helps you out.

your error code, is you have clogged burners, and they will have to be cleaned,
THIS IS A GAS PRODUCT, INCORRECT REPAIR CAN CAUSE A EXPLOSION, AND DEATH CAN OCCUR. IF YOU DO HAVE THE PROPER TOOLS SUCH AS MANOMETER AND LEAK DETECTORS, I SUGGEST YOU CONTACT A SERVICE COMPANY

I have the same problem since i bought this stupid water heater, it sucks. I had there service men come out and all they did was clean the burner sensor. Few months later i had the same problem. Then I called customer service and they tried saying that it was the exhaust what was causing the problem. What i found out is that the flame SENSOR and not the BURNER is the problem. Remove the burner and clean/scratch of particles of the tip of the flame sensor, it may look like its clean but you just have to scratch the head off clean with a small metal brush. Then reinstall the burner back and you will be fine, but just for a few months. Then you will have to do the same all over again. Hope this will solve your problem temporally.

I had this problem with the C2 11 error code. My unit is 1.5 years old. I called Paloma and they emailed me an 11 page document to clean the burners. I am not an HVAC but I got the feeling that's who the instructions were for. Very difficult but you can do it if you're handy. You basically take apart 1/2 the unit, be carfull not to lose any screws and label all the little brackets that come off. It took me 2-3 hours to get to the burners. I used a can of air (for keyboards-electronics) to blow on the burners and clear any build up. After putting it back together (carefull to make sure the 3 gas tubes make a seal when re-installed) the unit works. I did this today so I'm not sure the unit will still work in a week/month. I am dreading having to do this every year to keep the unit running.

check the error blink code again as 56 is not a valid error code for the WD62525
Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

it looks like a blockage somewhere in the system, does it have a exhaust vent check its clear and also check the burner if its clear.
