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

SOURCE: Tankless water heater (Paloma) Has C2 11 error

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.

SOURCE: My Paloma tankless water heater flashes C2 11 error code

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. Email me with any Q's at Mario@myredr.com Good Luck 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.

SOURCE: Paloma tankless, gas, water heater, error code C7 76

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.

Hi Jorge,

Call Rheem at 1-800-432-8373 and tell them you have a c7 56 error code and they will tell you what is wrong. The c4 and c6 just indicate that the heater has turned off.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

Handie Andie

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


Copy following link for error codes and Rheem-Paloma tankless troubleshoot.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#error
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.

I have a paloma tankles water heater model #ptg-42pvn i am getting an intermitent error code C4,12. what is the problem?


Copy following link for Rheem-Paloma tankless troubleshoot and error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/How-to-install-gas-water-heater.html#install

If unit worked before: Maybe bad PC board. Maybe lack of required yearly maintenance.
Common error codes can be caused by not following maintenance protocol such as cleaning combustion parts, checking gas pressure, checking venting, and air intake, bleeding gas line etc.
Too bad Rheem-Paloma manuals do not show HOW to conduct this maintenance, leaving customer with many unknowns, and no way to oversee that maintenance performed by hired technician is complete, and matches recommended maintenance.
Sell unit on ebay, and install tank-type gas water heater.

Error Im getting is C8 82


Before calling service tech, copy following link for Rheem-Paloma troubleshoot resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
C8 is usually the PC board, or could be failed gas solenoid valve.
82 is gas-type-data-failure = program PCB for proper gas type, or proper altitude above sea level.

If this is new installation, Rheem-paloma might tell you to contact the installer.
If this is older tankless that worked before, then things point to failed PC board. Rheem-paloma may send you new PCB for free if unit still under warranty period for defect parts.

Rheem does not post service manuals, but will send instructions.
Hopefully the success rate for replacing your main PC control board will have better outcome than expected when replacing motherboard on your computer.
Perform regular maintenance to avoid some common error codes.

Error 13 paloma tankless hot water system. no hot water


Before calling service technician, open following links for error codes, Rheem/Paloma chat and tech support, and possible manual:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://www.fixya.com/support/t3444443-paloma_tank_less_water_heater_flashes

Error codes are considered start-point for troubleshooting.
Tankless manuals recommend yearly service including burner cleaning, gas pressure and plumbing check, de-liming etc to prevent problems and so technician is familiar with that specific unit.
