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.

    Contact Paloma/Rheem customer (800-432-8373) support and notify them IF you are getting a code "76" error. Rheem has recently extended the warranty on the "Burner Control Assm."; which is your problem. The C4-C8 portion of the error code, is where the unit stops the ignition process...burner fails to light, or gives you intermittent hot water. In either case, contact customer support .

    If this helps, please indicate so.

    Even though the original post by JZKlipper is over 2 years ago, and his comment is from a year ago, I called this morning his information still holds true for May of 2011. My capacitors are clearly raised on the top. This is funnily enough, the 4th item at home that have had blown caps, that I have replaced myself. This control board I have left for Rheem to repair though as it is till in warranty.

  • rpatterson35 Sep 08, 2011

    I just called Paloma and as soon as I said code 76, he said we'll send you a new control board and replacement instructions. It's a controller error that needs to be fixed by replacing the PCB. I looked at the four capacitors (green with silver top) and two of them had a yellowish-white crust on top of them.

    Yep, I'm looking at them right now. They are blown and leaking. I was not expecting the whole board to be coated in a glue, however! I'll call and see if I can get a replacement free. If not, I may have to hack it from the other side. I'll post a photo.

My Paloma tankless water heater had a code of C7 - 76. I called the service center at 866-720-2076 and they stated this code showed a communication error between the Water Heater and the thermostat; they stated it was still under warrantee and they would replace it for free. Also, I found out there was a recall related to the door properly shutting. To make it work while waiting for the repair, I would turn off the thermostat, wait 2-3 minutes, and turn it back on. Usually it would work for enough time to shower.

    I have the same code the only diff is that they are sending a contractor to replace the board instead of just sending me the board.

  • calmike54 Jun 02, 2011

    Thank you for your posting. It was of great help. I called the service center and they are mailing out the board and having a contractor install it.

It's the remote controller remove it(the remote controller wires) and see if it kicks on and works fine, if not you have more problems! it would probably be the printed circuit board

I just talked to Rheem at 800-432-8373. They are sending out a circuit board and "As a courtesy, a technician to install it". They were very helpful. I certainly would recommend trying them first.

I second what rpatterson said. Soon as I mentioned that code, he said it was the pcb board and they are over-nighting the new board and will have it installed free of charge! Talk about service! Also, it if I turn the unit off and back on, I typically can get a shower in before it stops working again.

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.
Fix any tankless problem yourself, any brand tankless, same day for $385, by replacing 1 part: the whole thing:

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.

My Boch 24ES Highflow Hotwater is showing Code 14 and only runs for i minute then shuts off


Code 14.
What water heater do you have?
Question posted under tankless Bosch, but these error codes start with a letter.
Rheem/Richmond etc Tankless has error code 14
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Paloma-Tankless-Error-Codes.pdf
Call tankless service technician.
Ask technician how much it costs to have recommended yearly service.

Or install whole new tank-type gas water heater yourself for $350 from local box store, and avoid the entire headache, then sell tankless online for parts.

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.

PALOMA PTG-74PVN-1 Code C8 12 my water heater


C8 is the last stop in the point of burner ignition and a total of eight error codes. Error code 12 is a supplemental code that means your LP gas supply is too low...have your LP tank service and try again.

My new tankless WH stopped working. It gives hot water for about 15 sec, then starts flashing C7 12 or C2 11. How can I fix this, We had it for a month now & it worked before.


11 The Gas Shutoff Valve is not opened
completely.

12 Gas Service has been interrupted.
LP Gas is running low. (LP models only)

I think C7 is where the startup sequence ended...and then you get the error code

If less than a month old...contact your customer support
