SOURCE: tankless water heater error code 11

I had the same code 11 with my Richmond tankless hot water heater.
The problem was with exhaust gasses getting sucked back into the intake tube. This robbed the combustion chamber of oxygen causing it to shut down. A simple adjustment to make sure those gasses could not mix at the intake/exhaust port fixed it.

SOURCE: Error code 13, replace

Before calling service technician, open following link for troubleshoot resources:
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

The same error code and problem on one person's tankless unit can have different solution than another tankless unit.
This is because tankless require perfect operation of parts and sensors while being affected by incomming water and gas issues, and venting, plus plumbing factors.
Replacing one part is not always the fix, since that part interrelates with so many other parts, each affected by the operation of the other, and operation of the chip and integrity of wiring and wiring connections.

Read manual for yearly maintenance requirements, and calculate those costs when figuring anticipated $1-8 monthly energy savings from owning tankless.
Check that your region has reasonably-priced, qualified service technician for your brand before buying tankless. And check part list and cost of parts before buying any water heater because these factors weigh-in after a few years of operation.

Repair most tankless problems yourself, same day, any brand, for around $330.

Indoor tankless 74-pvn. power went off and has returned. get error code 24 when try to power on


Open following links for Rheem troubleshooting resources, including Rheem chat, error codes, and possible manual.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Error codes are considered start-point for troubleshoot.
Error code 24 is malfunction of operational switch: press max or min button on PC board to reset, -or- replace PC board.
Max-min button is sometimes located above dip switches, and can be 1 button that is rotated with screwdriver or 2 separate buttons. Look at wiring diagram in manual that came with product.

I am getting a C2 11 code on my eco sense tankless water heater. There is also a flashing 24, any ideas? Thanks


Multiple error codes can mean PC board failure.
C2 11 is no ignition.
Error 24 is malfunction of operational switch: "press max or mim button on PC board, or replace PC board." On some models, max and mim button can be located just above dip switches, and rotates with screwdriver. See diagram in manual.

Error code e2 on Rheem tankless water heater


e2 is not shown among common error codes:
Error e2 might be: Brownout condition or too low of voltage to thermostat. Double check wiring and check for 24 vac between R and C. E2 will clear 15 sec after proper voltage is restored.

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

Model number and serial number are required for Rheem contact, and then they tell you what error code means without saying how to fix it, and then tell you to call service technician.

Tankless water heater manuals each say to have qualified technician perform yearly service. Most causes for common error codes are covered by yearly service.

Yearly service is fairly standard in the HVAC and water heater industry with advancement of high-tech 'energy' saving appliances. Of course all costs are energy, and the service call probably costs more that the 'energy' saved by energy-saving appliance. But with high tech stuff like tankless, it is good to have a reliable service guy who knows your machine.
