More information is needed.
Water heater is not identified.
Add a comment with more information from label on side of tank.

If you have gas water heater, then open following links to identify gas valve, and download error code diagnostic and possible service manual:

For power vent water heater with Honeywell gas valve: three flashes indicate pressure switch or blower temperature switch not working.
Typical causes appear on page 13 on manual: can be bad blower, bad switch, blocked vent, exhaust temperature too high.

Rheem RTG53DVP code 82


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

Error codes are considered start-point for troubleshooting, and give service technician direction for isolating problem.
Error 82 appears as 'gas type data failure' > 'Program PC board for proper gas type.'

Gas type is choice between LP gas and NG natural gas.
Gas type programming is controlled with dip switch setting.
I do not have service manual for product, and would not suggest changing dip switches without specific information beforehand.

Rheem-Tankless-water-heater I am showing a C2 then 11 flashing on my thermostate. what is wrong.


Before calling service technician, open following links for common error codes, Rheem chat, and possible manual.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/ErrorcodeTroubleshooting.pdf
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Error codes are start point for troubleshoot.
C2 11 is 'no ignition' or 'gas shut off vale is not open'
Gas shut off valve handle must sit parallel with gas line.
This kind of error code can be air in gas line, improper grounding at electrical outlet, bad igniter, shorted solenoid, loose connections, etc.
Most tankless manuals recommend yearly service, and that type of work usually covers cause for most common error codes: for example checking gas pressure, gas line, air in gas line, clean and check burner and combustion parts and igniter, inspect that vent condensate is properly draining and vent has good draft, clean water filter, clean air intake, check for loose wires, delime heat exchanger, test outlet with circuit analyzer etc.

C2 11 code


Before calling service technician, open following link for Rheem error codes and troubleshooting resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code C2 11 is 'no ignition'
Ensure you have gas to the appliance.
Ensure gas type and pressure are correct.
Bleed all air from gas lines.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Ensure igniter is operational.
Check igniter wiring harness for damage.

There is no service bulletin covering how to perform these actions.
Rheem will ask that you call qualified service technician, who can give you tips and tricks for keeping the unit working, including opportunity for yearly service that will eliminate the expected $1-8 monthly savings from owning tankless.
Read manual for yearly maintenance needed to keep unit working at prime efficiency.

Have Error code FO, no hot water. Press reset and water gets warm for few seconds then goes off again.


1) BOSCH website shows error codes.
FO does not appear:
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

2) I do not see FO error code listed on Internet search
Other FO questions at fixya seem to have no answer:
http://www.fixya.com/tags/error_f0_bosch

3) At this point, I would suggest calling a service technician.
While waiting for service, read manual cover to cover several times.

4) Your manual is valuable resource, and shows the word 'maintenance' and 'troubleshoot' frequently.
Tankless are maintenance heavy, and should be de-limed each year.
U-tube search "delime tankless water heater."

5) Also explore Bosch website for your manual and other valuable information.

6) When service tech arrives, ask that person for tips and tricks about your unit that will help you maintain your water heater.

7) All costs are energy. Install DIY tank-type gas water heater and avoid the whole headache.

RTG 74-PVN-2 Rheem tankless water heater. Works fine for a month or so at a time, then I get C2 - 13 error code. Did I hear this model was recalled?


Before calling service technician, open following link for Rheem troubleshoot resources including error codes and typical manuals.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Recall website:
http://www.tankless-recall.com/tanklessSearch.aspx
Error code C2 13 call Rheem.

Read manual cover-to-cover to make sure your tankless water heater receives yearly maintenance required for unit to continue working.
Tankless are maintenance heavy which can quickly eliminate any promised energy savings unless you de-lime and troubleshoot and read tips-and-tricks others have written and glean information from service technician who visits your house. Mostly glean how much tankless repairs and parts cost vrs buying whole new tank-type gas water heater at local box store, since all costs are energy.
