did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

I suggest you call tech support. I had a similar problem, and after walking me through a few tests, they determined it was likely a motherboard problem and are sending a new one. At 2 1/2 years, your unit should still be under warranty...

Even though you are not getting an error code, there are may be some diagnostics in the controller that can identify whether it's an electronic (controller/sensor) or a heat exchanger issue. I would contact Rheem tier-2 support.

I have c7 code


it is a communication problem between remote control and tankless unit

Temporary fix:
1 Turn off electricity to tankless and remove cover. Find two terminals that remote control connects to.
2 Disconnect remote control wiring. Turn electricity back ON.
3 Open hot water tap and see if unit works as expected.
4 Without remote, tankless will heat water to default 120 degrees F and will run without the remote.
Contact Rheem they may send you another pcb board.

How reliable is your AC? With the digital r/c connected, every time the heater recovers from power outage it's in the OFF default state. If you can not fix the power issue, disconnect the remote control. The w/h will recover in the ON state.
