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

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 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.

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

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 tankless ptg42 water heater error code c4/13


4 error message, the 4th (last) error code is #13, not enough oxygen.

Check the location of the heater, if it is fine the ODS sensor (actually is a thermal couple) is bad.

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.

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.
