SOURCE: I have a Rheem tanklees water heater, model

Contact Paloma/Rheem 866-720-2076. Super nice! I just called regarding mine. Having same problem Rheem Paloma sending parts out tomorrow overnite. Try turn it on/ off by moving tiny switch under the unit that tells you the temperature. Run your fingers along the bottom to find it. That is a temporary fix. Below is a website with all the error codes, so you know what is wrong. Good luck and blessings!

Get hot water from your Rheem tankless during a code 76 error

This doesn't always work, but on the Rheem tankless Gas/Propane water heater, if you're experiencing a code 76 error; disconnect the remote control unit (either from the water heater or the remote) by lifting the wires for the remote connection. Typically you'll get a C1-C8 error code, followed by a code 76; if you're getting a straight code 76 and nothing else, this procedure probably won't work.
Code 76 is a total power supply failure on the printed circuit board (PCB) assembly, which is the communication/power supply for the remote control unit. But, if you're getting a supplemental code (C1-C8) this procedure will most likely supply you with hot water until the replacement PCB arrives.

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.
