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.

that is the water inlet temperature sensor fault.. check and clean scale from sensor or have it replace by a qualified technician

I have a code showing C7 13 the heater runs for about 2 to 3 mins then shuts off. Any suggestions?

I do not have a solution for you, however mine does th same thing. Did you ever find a solution?

check to make sure circuit breaker is big enough to handle your unit if not get correct size

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.
