It indicates that the circuit breaker shorted .The component in question is a thermal circuit breaker, of the sort which does not reset. Once activated, it is destroyed,

The failure is easy to verify. If blown, there will be powdery white residue on the inside of the bottom plastic cover near the part. Also, an ohmeter will show an open circuit across the contacts. (Unplug the unit before measuring!)

Screws to remove the bottom cover are three tamper resistant torx screws.

If unable to find an exact replacement, use a thermal fuse in the same power and temperature range (10 Amps, 300 degrees C trip).to solve the issue.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

Is the power switch on the side turned on? Is the outlet it is plugged into functional? Try plugging something else in there.

    You are going to have to dissemble the unit and check the heater for continuity with an ohm meter. If you get a 0 reading the heater is defective. There is also a thermal sensor that you need to check with the ohm meter. Likewise if it reads 0 it is defective. Once you open the unit up be very careful with the seals and do not damage them or the coffee maker will leak when reassembled.

De-scaled by using vinegar as suggested now every cup tastes like vinegar

Keep filling your water reservoir with water and running it through, until it clears up, it might take a few fill ups of your water reservoir to get the vinegar taste out.

How do I get the boiler on my rowenta steam generator to fill? I was given this model.

You should only use distiller water in the steamer. Never ever use tap water! This is what caused lime and scale build up.
Since it's to late, you have nothing to loose by trying this to descale the unit:

Put up to one cup of white vinegar into the reservoir. Fill 3/4 of the way with water. Turn unit on and let it heat up, but DO NOT RUN STEAM THROUGH THE LINE. Once heated up, turn unit off and let it set for hours. Drain and rinse well. Then run a water only batch through the steam cycle. There are companies that sell special de scaling solutions. But hopefully, the vinegar will work.

How do I flush this unit

1) Copy following link for steps showing how to run white vinegar through Rheem tanklessx heat exchanger to partially remove scale that coats heat exchanger and reduces unit efficiency and causes error code IL:

2) Tankless are prone to scale inside heat exchanger and require yearly deliming to mitigate effects. Do the required yearly maintenance to avoid common error codes.

3) Expected cost of maintenance and repair is more expensive than estimated $1-8 monthly energy-bill savings from owning tankless.

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:

Error IL usually means delime the unit.
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.

Service error #21

I believe that is a water sensor error...your machine may be coated with lime preventing the machine from sensing water...generally if your unit is plumbed for water the boiler would need to be removed and de-limed...if you have a "pour over" unit...then try pouring white vineger mixed with water...50/50...into the normal fill port...let it sit for an hour or two and drain or flush...the vinegar is a safe way of dissolving the lime...phillip

Flashes il

Before calling service technician, open following link for Rheem tankless resources including error codes and possible manual.

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 lost my manual. How do I de-scale? Does this not allow you to brew a cup until it has been de-scaled?

To begin, you will need the following:
  • 48 ounces of undiluted white vinegar
  • Large ceramic mug (do not use a paper cup)
  • Access to an empty sink

PREPARE Step 1: Empty the water in the Water Reservoir. Step 2: Disable "Auto Off" features.
FILL AND CLEAN Step 1: Pour approximately 48 ounces of the vinegar into the Water Reservoir. Step 2: Place a large mug on the Drip Tray Plate and run a brew cycle. DO NOT USE A K-CUP, just press the BREW Button. Pour the contents of the large mug into the sink. Step 3: Repeat the brew process without a K-Cup until "ADD WATER" is indicated. Step 4: Now let the Brewer stand for at least 4 hours while still on. Step 5: Discard any residual vinegar and rinse the Water Reservoir thoroughly.
RINSE Step 1: Ensure the Water Reservoir is filled with fresh water. Step 2: Place a large mug on the Drip Tray Plate and water brew cycle. Pour the contents of the large mug into the sink. Step 3: Repeat brew process until "ADD WATER" is indicated. Step 4: You may need to perform additional water brew cycles if you notice any residual taste. NOTE: If "DE-SCALE" is still displayed after completing the procedure, repeat the de-scaling procedure above.

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:

I want to know how to drain the water and get the lime out of the tank

Unplug, cool down, remove carafe and basket, turn unit horizontally over sink. It will drain faster if you remove the screw on "distributor" (nozzle). OR do not drain. Just add the plastic pitcher full of a 50% white vinegar solution, let heat then turn off for 1 hour. Drain OR add 4-5 pitchers of cold water to rinse.
