Hi, I too had the problem, as did a lot of others i noticed from my research in to finding an answer. I decided to pull the heater apart myself as I am a handy mechanical type of person. a long story short, I pulled the main solonoid valve (POV) apart and found a brass piece dislodged from between the rubber diaphram and the plunger, I placed it back into its position, put it all back together and have not had the heater cut once, it is going great. hope this helps. if you are handy you can do it, I can share instructions if you need to regards peebee1

    I have the Paloma PG711-FR as well and am having the error-12 code issue. Peebee1 could you please send me the instructions for the solution you have?

    HI Metalicro,
    It has been some time now since I pulled the heater apart, but basisally put the heater on a bench with plenty of room, removed the screws retainng the covers, exposing the pipework, wires etc. also remove the supply pipe from the heater.
    Taking note of the position of the wires to replace them correctly. There is nothing that you can damage when unscrewing the pipes, taking them off and cleaning them out etc, (blowing through them out with a compressor which is what I did when I was first looking for the problem)
    There are a couple of valves within the mechanics of the heater, I pulled both apart for inspection and a clean, as I said if you carefull of how you pull them apart they can be easily put back together. The POV valve by memory has a top on it retained by small screws, when removing the top it exposed a diaphram and with the problem with my heater, there was a small brass type piece (about the size of a 5 cent piece) shaped to look like a cymbal. This brass piece was dislodged preventing the diaphram from operating correctly hence the 12 error. I placed the brass piece back on top of the diaphram and put the valve back together. (In heinsight I should have put a dab of silcone on the diaphram to retain the brass piece preventing it from dislodging again). I put it all back together and it has not missed a beat since, I am at this moment using the heater 26 may 2011). I did clean out every bit of the Heater when i had it apart, this may have helped I dont know??, anyway it was a solution that worked for me, as from other comments by others who had the same problem and paid silly money to have repairs done, I was not about to have a $1000 heater sit around useless, Good luck, please let me know how you got on. Kind Regards peebee1

My Paloma pg-711fr is turning itself off and error 12 comes up

Copy following link for error codes and Rheem-Paloma tankless troubleshoot.
Add a comment and say if this is new installation.
Call Rheem and hear them tell you to call the tankless installer, or hire local service technician to check your tankless computer that heats water, and catch up on required monthly and yearly maintenance. For example cleaning burner and flame rod, or replacing bad flame rod, or installing correct gas line, or checking gas pressure etc.
Fix any tankless problem yourself, any brand tankless, same day for $385, by replacing 1 part: the whole thing:
Do not install tankless.

Try turning the thermostat uo a small amount and see if this makes a difference. I suspect the control board is bad but I would try adjusting t-stat before I spent money on board or service call. Thank you

Paloma tankless water heater won't stay on during operation.

I have a Paloma model RUTG-74PVP, I had the same problem after less than a year. The unit would operate for about 90 seconds and then shut off with an error code of C13. Paloma kept trying to blame it on "lack of combustable oxygen" ,, my unit is in the attic, so we added more soffit vents and an electric attic fan. We still had the problem and Paloma blamed it on the lack of a condensation trap (so I added one), & then on the 1" dedicated LP Gas line (so I had the propane guy come run a water column test). Finally, 4 months later , Paloma had a service man come down (100 miles away) to see what was wrong (He told them to replace it. They paid for the unit and labor. It ran perfect for about 9 months and then started doing it again. So I called the same representative and asked if they were gonna replace this one too? He said nope, it's no longer under warranty. But he did tell me how to fix it this time. It required taking the the whole unit apart and cleaning a ceramic piece in the very back of the heater. It was hard to get to, and it took about 2 hours of disassembling and reassembling. The good news is Paloma will walk you thru it on the phone and once it's was done, my system worked properly again. The bad news is,, it only lasted for about 9 months. So now I need to do it again. I'm hoping that someone will read this and tell me that there is a filter (like a gas filter) that I can install that is easier to get to.
