Remote is flashing C8 and 76, alternating. I turn the unit off, then back on, and I get hot water for about 10 seconds, then it goes cold and the same error message occurs. Unit is Rheem Main Remote...


Before calling service technician, open following links for Rheem tankless resources including error codes and Rheem chat.
Disconnect wires from remote to see if system stabilizes. Unit will heat to default temperature without remote.

Error codes are considered start-point for troubleshooting.
C8 76 can mean PC board failure.
76 can mean communication failure with remote control

The hot water will not come on intermitently. I


if your on a private well, it sounds as though your loosing enough water pressure to shut the heater off,.(which is right before the water pump comes on),....tankless heaters turn on by sensing water flow, and of course off when flo stops,......water pressure tanks often need to be re-charged with air for pressure to stay even,....does your water pressure fluctuate?
