Question about Rheem EcoSense by 4.2 GPM Tankless Water Heater LP Gas

1 Answer

Rheem tankless water heater gives error code, flashes 80. Also what do I use to seal the exterior of the vent? Should the vent outside smell like gas?

I just purchased a rheem water heater and it often times turns off when trying to start up or I will get an error code and it flashes 80. Sometimes it will reset itself but not always. Please help me.

Check to make sure that your flue pipes are together if the have not been put together properly it will not start, it has to pull in cold air while exhaust is forced out,, if it isn't right it will pul exahust thru the cold air intake and shut sown or not start at all,, you might want to call who ever installed it,they are supposed to warraty it for 1 year on labor at a min, to be able to install them thru the company,, rheem,, they are supposed to be quilaifeid and have a card that states they took the class to have the knowledge to do so.

I have a Richmond tankless water heater and it has L1 error code...can somebody help me with this?


Might be able to help. Except L1 does not show on any error code file.
Copy following link for Rheem Richmond Ecosense etc computer water heater troubleshoot resources
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Are you sure the error is not IL? Delime tankless.
Or UL flashes and indicates reset.
Or CL flashes and indicates fault history is cleared.
Or error 11 combustion failure? Call for service.
Or P1? Low water pressure, clean water filter check for leaks and crossover caused by bad single-handled faucet cartridge.
I recommend calling Rheem to find local technician who is qualified to work on tankless computers. Tankless are not ordinary water heaters, and they require continual maintenance to avoid common error codes, especially as unit gets 2-3 years old, after warranty has expired.
The required maintenance and expense of repairs, and general fact that people cannot make their own repairs, make tankless computers a bad choice for heating water.
If unit is 4-5 years old, it might be best to install tank-type heater for $385 from Lowes and cut losses.

The computer code 14 comes up on the computer what does that mean.


Before calling Rheem or service technician, open following link for troubleshoot resources including error codes, Rheem chat, typical required maintenance manual, and possible product manual:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Error codes are start point for troubleshoot.
http://waterheatertimer.org/pdf/ErrorcodeTroubleshooting.pdf
Error 14 is 'overheat wrap fault.'
This can include venting problem, failed heat exchanger, bad safety circuit, gas problem.
Rheem does not have a service manual posted for this specific problem.

Additional information: Tankless water heaters consume large amounts of gas during combustion. The combustion burns away hydrogen and the remaining poisonous byproduct is vented into the atmosphere at each home day and night.
Byproduct includes acidic water vapor that condenses along the vent pipe and drips back down vent.
Each tankless vent pipe has a drain line that directs acidic water into household drain.
If this drain line becomes clogged, or if vent was not installed correctly, then water drips down into heat exchanger and can erode or crack exchanger.
The typical maintenance manual above shows steps that can solve many tankless problems before they happen.

I have a poloma model/ pt62-42pvn its flashing error code c4 76 i have had no hot water for six days now need help


1) Before calling service technician who can test parts, open following link for Rheem resources including error codes, Rheem chat and phone number, possible manual:
If local technician cannot solve problem, Rheem can probably recommend a person.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

2) Error codes are start-point for troubleshooting.

3) Multiple error codes can indicate PC board failure.
If your computer motherboard fails, most people feel the computer is compromised even after motherboard replacement.

4) Error code C7-76 is communication error with remote, and can include bad remote, bad wire to remote, loose wire, or bad PC board.
http://waterheatertimer.org/pdf/Rheem-error-code-C7-76.pdf

5) Error C4-13 can include part failure, vent problem, oxygen depletion, and can also include PC board failure.
http://waterheatertimer.org/pdf/Error-code-13.pdf

6) Tankless routine maintenance manual:
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

7) Some posts about tankless concede that qualified technician was unable to repair unit.
Solve most tankless problems yourself, same day, for about $350.

Rheem tankless water heater eco180-dvn has flash error code 13. Any solution? Called Rheem, only said venting problem, wouldn't provide the next step. Thank you.


Rheem wants customers to call trained service technician since error codes are start-place for troubleshooting, and problems can be combination of issues.
Risk of CO poisoning from improper vent, or clogged drain line causing damage to heat exchanger, and risk of homeowner working on complicated gas-burning appliances are reasons why Rheem instruction manuals recommend yearly maintenance by trained technician.
That maintenance would typically cover most common error code issues, and homeowner could gather tips and information from service tech.
