Rtg74pvn2 rheem tankless water heater gas problem


1) You want the truth: Forget tankless.
There are many tankless water heaters with insoluble problems.
And endless problems.
Rheem knows it.

2) Do you really expect your home computer to work flawless after replacing motherboard?
Get your money back from Rheem, or get a full replacement.

3) OR fix water heater yourself today: Install tank-type gas water heater for $350 from local box store.
FYI: Do not buy Rheem, Richmond, Ruud, GE as these units from Rheem have problems that require service technicians.
Instead buy Whirlpool, American, State, Craftmaster, Reliance, Kenmore, as these units from AO Smith have fewer problems and can be repaired by homeowner using simple part replacement.

Rheem Integrity 20 not always lighting. Showing code C2 11


Before calling service technician, open following links for Rheem/Paloma troubleshoot resources including error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/No-Error-Code.pdf

C2 11 is no ignition.
Clean combustion parts yearly as recommended in manual is first step.
Other causes can be loose wiring, bas gas valve, dirty air intake, bad venting, bad sensors etc.
Test these parts using service manual. Call Rheem since Rheem does not post service manuals.

Can you tell me why my heater turns off when I turn on my washer and the kitchen sink and its not just when Im washing its also when I shower.. and the error code is C76 or Double 00


No I don't know why it turns off and gives error code 76.
Those two things seem unrelated.
Before calling service technician, open following link for Rheem troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 76 for possible remote control solution:
