My control unit keeps alternating between 120 and IL. Cannot find code IL


Before calling service technican, copy following links for general troubleshoot resources and error codes, and manusls, and Rheem contact information:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Rheem-CondensingTankless-maintenance-2012.pdf

Error IL usually means delime the unit.
http://waterheatertimer.org/pdf/Rheem-De-lime-tankless.pdf
Read your product manual for yearly/monthly maintenance schedule.
Tankless are maintenance heavy and must be delimed each year.
Deliming using white vinegar take about 1 hour, and will not restore full efficiency to unit.
Tankless have the habit of forming lime deposits inside the heat exchanger, even with softened water.
Tankless cannot be exposed to more than 11 grains hardness in water.
Don't buy a tankless next time.
Read the manual first.

My rheem was flashing IL . I flushed with 2 gallons of vinegar for 45 minutes. however when I restarted it still is flashing IL. Does something in the remote need to be reset?


Before calling service technician, open following link for Rheem tankless troubleshoot resources, including on-line chat
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Rheem technical service bulletin for de-liming:
http://waterheatertimer.org/pdf/Rheem-De-lime-tankless.pdf

De-liming Manual says:
10. Turn on the water shutoff valves, run a hot water tap to
purge any air from the water lines and check the system
for any leaks.
11. Turn on gas, electricity, and remote control thermostat
and set the desired temperature.
12. Run hot water from several locations to check the operation
and performance of the water heater.
If you have difficulties please contact the Technical Service
Department at 1-800-432-8373 or your local service agent.

I am getting a IL code on my display


IL code is: water heater has lime deposits.
Tankless should be de-limed each year using white vinegar..
Search U-tube for "de-lime tankless heater" to see how to do this yourself, or call service technician.
There are special fittings that can be added to tank at the hot-n-cold ports that let you easily de-lime your water heater each year.

Typical manual shows error IL on page 33:
http://waterheatertimer.org/pdf/Rheem-RTG74IndoorOutdoor_owners.pdf

Typical manual also shows regular maintenance on page 29.
The word maintenance is used throughout the manual.

Research shows that regular de-liming will not restore full efficiency to tankless water heaters:

Thermostat flashes IL ? Model PTG-53PVN


http://www.palomatankless.com/owners/homeowner+trouble.lasso#28-11
The Controller displays error code "1L."
There is a build-up of lime in your Paloma.
Contact your plumber to service the Paloma by flushing out the lime.
Also search u-tube for flushing lime out of tankless.
