Error Code 76 signifies a “Communication Fault with Remote Controller” on your Rheem Continuous Flow Water Heater. This means the main unit and remote controller are not communicating properly, potentially disrupting operation or temperature control.
Initially, reset the communication by turning off the power at the isolation switch, wait several minutes, and switch power back on. If communication is not restored, the wiring or remote control may require professional servicing. Contact Hilton Plumbing for safe and effective repair.
