Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

A 76 code (C8 is where in the cycle the error occurred) is a remote control communication error. Try this, unplug the unit then remove the remote control wires from the terminals on the heaters control board then plug it back in. Does the unit work OK?
