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

Read your manual for troubleshooting, advisories and required maintenance.
Tankless are maintenance heavy.
1L means tankless heat exchanger has lime build-up.
De-lime tankless unit.
U-tube has videos for de-liming tankless, but there is more to consider:

De-liming is yearly maintenance requirement.
Tankless are prone to lime build-up
Regular de-liming will not restore full efficiency to tankless unit.
Tankless cannot be exposed to water with more than 11 grains hardness.
Temperatures over 135 can cause minerals in water to harden on metal surfaces of any water heater.

Also clean Tankless water filter each month, and clean and maintain burner and combustion chamber yearly.
The cost of maintenance and cost of expected repairs and cost of parts plus cost of original installation will never pay back the $1-8 monthly savings on gas bill. All costs are energy.
Make sure there is qualified service technician in area before buying tankless.

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.

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.

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:

Contact your plumber to service the Paloma by flushing out the lime.
Also search u-tube for flushing lime out of tankless.
