Question about Rheem Tankless Water Heater Main Remote Control

I have a Rheem RTG-74 tankless water heater with the remote control (UMC-117). The remote has shut off and won't turn back on. I've checked the circuit breaker and it's fine. Any suggestions?

2 yr old ecco sense UMC 117 unit flashes 38 beeps and wont give hot water


1) Copy following link for Rheem tankless troubleshoot, including ecosense.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

2) Probably needs new circuit board.

3) Product manual usually give list of required yearly maintenance.
Perform the maintenance, just like changing oil on car, and then service technician is familiar with your water heater and can count on your money each year around Christmas.

4) For independence, reliability, cost, and convenience, don't buy tankless water heater, or any other expensive/complicated water heater that requires yearly maintenance, and generally cannot be repaired by homeowner.

Thermostat model UMC 117 keeps coding C7 why?


Generally, C7 is communication problem with remote
Error codes are considered start point for troubleshoot.
Causes can be: Bad remote, bad wire to remote, loose wire connection at remote, loose wire connection at unit, bad PC board.
In no particular order:
Check wire connections.
Disconnect remote and let water heater control temperature at default 120 degrees F, and if no further problem develops, then that might eliminate PC board as source of problem.
Replace wire to remote.
Replace remote.
Call service technician to diagnose problem.
Contact Rheem about PC board and other options.

Before calling service technician, open following links for troubleshooting resources:

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

Why is the controller UMC-117 keeps blinking c8?


C-8 error codes could mean anything from the fan not starting, a bad control board, or a blown capacitor. Best bet would be to call Rheem customer service and they'll ship part or suggest licensed contractor to troubleshoot and replace what's necessary.

Some older questions have information that is useful, and varied

Open typical manual to review required regular maintenance for tankless on page 29
The word maintenance is used throughout manual, indicating that tankless are a yearly budget nuisance

All costs are money.
You can also add simple tank-type water heater that can be turned on when tankless is on the blink.

My umc-117 flashes 76 then -0 what causes it to do that?


76 is the controller error, check your wiring to it to make sure it is connected well , if it's not that the controller is shot , from there it could be the one of the control boards
