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: 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.

Error code C4 76


Error 76 is communication fault with remote control, or bad PCB board.

Call Rheem, and they will recommend service technician.

Make sure your unit is serviced yearly to prevent common error codes. Which defeats the robust $100 expected yearly savings from owning a tankless water heater.

My tankless indoor water heater has an error code C4 76


Error code 76 indicates a communication error with the electronic board and the unit. Call Paloma/Rheem with the serial number and model number of your unit and they will, in most cases, send you a new board with instructions on how to easily replace the board.

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.
