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.

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:

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:
