Q: Do all the indicators blink after turning on - is this normal?

Yes, this is a perfectly normal behavior of your KRUPS EA897B10 EVIDENCE. Upon startup, the machine automatically runs its preheating and rinsing cycles . During these phases, all recipe buttons blink (in 'breathing' mode) to indicate that a maintenance or preparation cycle is in progress. Just let the machine complete these automatic cycles - it only takes a few seconds. Once the preheating is finished, the indicators will stop blinking and the device will be ready to operate normally. If the indicators continue to blink after several minutes or if a red alert indicator appears with the maintenance icon, refer to the manual for the required maintenance procedures.

Q: How to permanently adjust the amount of coffee beans and water on the KRUPS EA8100?

The KRUPS EA8100 allows you to control the grind size via the grind size adjustment button (turn left for a finer grind, right for a coarser one). This grind size indirectly affects the consumption of beans. Regarding the amount of water , it is adjusted before each preparation using the rotary control button on the control panel. The recommended volumes are: Espresso: 30-70 ml Lungo/regular coffee: 80-220 ml However, the manual does not provide a permanent setting to define a default amount of water or beans . You must adjust the amount of water for each preparation according to your preferences. The machine does have three permanent settings accessible (water hardness, coffee temperature, automatic shut-off timer), but not for the quantities.

Question 1

Why is the KRUPS EA8100 coffee machine not heating and how can I fix it?

Accepted Answer

If your KRUPS EA8100 coffee machine is not heating or not turning on, here are the solutions in order of priority:

1. Check the power and preheating

Press the ON/OFF button to turn on the machine.
Observe the indicator light: it should first blink (preheating in progress, about 3 minutes).
If the light does not blink at all, first check the power outlet and the circuit breaker fuses.

2. Start the initialization cycle (if first use or after long inactivity)

If this is the first time turning it on or if the machine has been unused for a long time, you MUST perform the initialization cycle:

Place a container of at least 0.6 liters under the coffee outlets and steam nozzle.
Press the rinse/maintenance button.
Wait for the indicator light to become steady (about 3 minutes) - this means the circuits are filled and the machine is ready.

3. Check for descaling (common cause)

If the machine is not heating properly or not producing steam, it is likely scaled:

Fill the water tank with lukewarm water up to the “CALC” mark.
Pour in a packet of KRUPS F054 descaler (40 g).
Press the CALC button and follow the 3 phases of the descaling cycle (you will hear beeping sounds).
This operation takes about 20 minutes and fully restores heating capacity.

If after these steps the light still blinks without becoming steady after 3 minutes, or if the machine still does not respond, an electrical fault or internal heating issue may be the cause and will require professional repair.

Question 2

Do all the indicators blink after turning on - is this normal?

Accepted Answer

Yes, this is a perfectly normal behavior of your KRUPS EA897B10 EVIDENCE.

Upon startup, the machine automatically runs its preheating and rinsing cycles. During these phases, all recipe buttons blink (in 'breathing' mode) to indicate that a maintenance or preparation cycle is in progress.

Just let the machine complete these automatic cycles - it only takes a few seconds. Once the preheating is finished, the indicators will stop blinking and the device will be ready to operate normally.

If the indicators continue to blink after several minutes or if a red alert indicator appears with the maintenance icon, refer to the manual for the required maintenance procedures.

Question 3

How to permanently adjust the amount of coffee beans and water on the KRUPS EA8100?

Accepted Answer

The KRUPS EA8100 allows you to control the grind size via the grind size adjustment button (turn left for a finer grind, right for a coarser one). This grind size indirectly affects the consumption of beans.

Regarding the amount of water, it is adjusted before each preparation using the rotary control button on the control panel. The recommended volumes are:

Espresso: 30-70 ml
Lungo/regular coffee: 80-220 ml

However, the manual does not provide a permanent setting to define a default amount of water or beans. You must adjust the amount of water for each preparation according to your preferences. The machine does have three permanent settings accessible (water hardness, coffee temperature, automatic shut-off timer), but not for the quantities.

Question 4

How to descale the KRUPS EVIDENCE EA897B automatic coffee machine?

Accepted Answer

Regular descaling of your KRUPS EVIDENCE EA897B automatic coffee machine is essential to eliminate limescale and ensure optimal operation. The machine will automatically notify you with an alert (LED), but you can also manually start the program at any time.

Necessary accessories: You need a KRUPS descaling sachet No. 3 specially formulated for this machine and a container with a minimum capacity of 600 ml placed under the coffee spouts to collect the liquid.

Descaling procedure:

Turn on your machine and press the T button (maintenance button) located on the control panel
Select the “Descaling” option on the LCD screen
Fill the water tank with fresh water and pour the contents of the KRUPS descaling sachet No. 3 into the tank
Position the container (minimum 600 ml) under the coffee spouts to collect the liquid
Confirm the start of the program. The descaling cycle lasts about 20 minutes - let it run without interruption
Once the program is complete, completely empty the water tank
Fill the water tank with clean water and run several rinse cycles to eliminate any residue of descaler
Clean the drip tray and the coffee grounds container

Descaling frequency: KRUPS recommends descaling your EVIDENCE EA897B three times a year. However, the frequency may vary depending on the hardness of your local water. Hard water requires more frequent descaling (up to once a month), while soft water may only need quarterly descaling. If the machine prompts you for descaling, please heed this alert to preserve the longevity of your device and the quality of your beverages.

Question 5

How to adjust the coffee strength on the KRUPS EA8100 automatic coffee machine to get a lighter coffee?

Accepted Answer

On your KRUPS EA8100 coffee machine, the main setting to achieve a lighter coffee is the grind size adjustment. This button allows you to adjust the grind size of the coffee, which directly influences the strength and taste of your drink.

To get a lighter coffee, turn the grind size adjustment button to the right. A coarser grind (less fine) reduces the extraction of compounds and produces a milder and clearer coffee. Note: this setting should only be varied during grinding, and never force the button.

Additionally, you can increase the water volume of your preparation. The larger the water volume, the more diluted and lighter the coffee will be. You can modify this amount according to your preference for each type of drink (espresso, long coffee, etc.).

Another customization lever concerns the strength of the brew. Depending on your needs, you can decrease this intensity to reduce the amount of ground coffee used, which also contributes to a lighter coffee.

For the best results, we recommend combining these adjustments and performing a few test brews. After a few trials, you will find the ideal setting that matches your taste preferences. The quality of the water used (fresh, without a chlorine taste) also plays an important role in the final result.

Question 6

What does the flashing of the water tank and coffee grounds indicators mean on the KRUPS EA 8118 automatic coffee maker?

Accepted Answer

On your KRUPS EA 8118 automatic coffee maker, the flashing of the water tank indicator (indicator O) and the coffee grounds indicator (indicator N) corresponds to specific maintenance signals that require immediate actions to ensure proper functioning.

Water tank filling indicator (single flash): This signal indicates that the water tank is empty, missing, or improperly positioned. Remove the tank and fill it completely with fresh water, then reinsert it firmly until you hear a click. Ensure it is properly engaged in the machine. If the indicator continues to flash despite a full and correctly positioned tank, the sensor may be dirty - clean the contacts and try again. In some cases, the coffee cycle may have been interrupted due to lack of water during preparation; simply fill the tank for the machine to resume automatically.

Grounds container emptying indicator (single flash): This signal indicates that the coffee grounds container is full (maximum capacity of 9 coffees) or that the drip tray is full. Remove and completely empty the grounds container, then firmly replace it. Also, remove the drip tray below, empty it, and put it back. Important note: the indicator will remain lit if the container is not properly pushed in or if it was replaced before 4 seconds - wait a few seconds before reinserting the container.

Double flash or simultaneous flashing of both indicators: In some cases, both indicators may flash together, which means you need to empty the grounds container AND the drip tray at the same time. Perform both emptying and cleaning operations as described above. If you have requested a double coffee (quick double press on the coffee button), the flashing of the water indicator may indicate that the machine is performing a cycle of 2 coffees - this is normal and temporary.

Special case - Container absent or improperly positioned: If the flashing persists, check that the grounds container and the drip tray are properly engaged and securely clipped in place. Improper installation blocks the operation of the machine and the indicators will remain active until corrected.

If after these checks the indicators continue to flash abnormally, contact KRUPS customer service, as this may indicate a malfunction of the sensor or a more significant maintenance issue with the machine.

Question 7

How to effectively clean the KRUPS EA8100 automatic coffee machine?

Accepted Answer

To keep your KRUPS EA8100 automatic coffee machine in excellent condition, regular cleaning of the removable parts is essential. After each use or daily, remove and empty the coffee grounds container to prevent overflow, then clean it under running water. The drip tray is equipped with floaters that indicate when to empty it: remove it, empty it, and clean it with clear water as well. Also remove and clean the coffee drawer to eliminate any residue of coffee beans and powder that may accumulate.

The steam nozzle, if you prepare cappuccinos or lattes, requires special care. This nozzle is detachable for deep cleaning: wash it in warm water with a little non-abrasive dish soap using a brush. Rinse it thoroughly, dry it, and especially check that the air intake holes are not blocked by milk residue. Use the provided needle to unclog them if necessary. Never wash the steam nozzle in the dishwasher. To prevent milk from drying on the auto-cappuccino accessory, clean it immediately after use by running a steam cycle with the pot filled with warm water. You can also use the KRUPS liquid cleaner available as an accessory for this task.

Automatic cleaning program: Your device will alert you to the required cleaning (approximately every 300 coffee or espresso preparations) by the flashing of the “CLEAN” indicator light. This program lasts about 13 minutes and is essential to maintain the warranty. Use only KRUPS cleaning tablets (XS3000) available from KRUPS Customer Service. Before starting the cycle, remove and empty the coffee grounds container, the coffee drawer, and the drip tray. Replace these items and fill the tank to the brim with water. Place a container of at least 0.6 liters under the coffee outlets. Open the maintenance hatch, insert the cleaning tablet into the designated slot, and then start the program. The first phase lasts about 10 minutes; when a beep sounds every 10 seconds, empty the container and the drip tray, then restart the program for the final phase (about 3 minutes). The cycle is complete when the “CLEAN” light turns off.

Descaling program: The device will alert you to the required descaling by the flashing of the “CALC” indicator. Before descaling, remove the Claris Aqua Filter cartridge (F088) if your machine is equipped with one. The program lasts about 20 minutes. Fill the water tank with warm water up to the “CALC” mark and add a packet of KRUPS descaler (40 g, reference F054). Place a container of at least 0.6 liters under the coffee outlets and the steam nozzle to collect the used water. Start the program: the first phase lasts about 8 minutes. When a beep sounds, empty the container and replace it for the next phase. Restart the program for the final phase (about 6 minutes). The cycle is complete when the “CALC” light turns off. Then fill the tank with clear water and run one or more rinse cycles by pressing the steam button to eliminate any traces of descaler.

For regular rinsing of the circuits, use the coffee circuit rinsing function accessible at any time: place a container under the coffee outlets and briefly press the rinse/maintenance button to purge the circuit. You can also use the long rinse function (about 2 minutes) by simultaneously pressing the “CLEAN” and “CALC” buttons. Please note that after cleaning or descaling, a little steam and hot water may naturally come out of the steam nozzle during the first coffee preparation (self-priming): this is normal. During cleaning and descaling cycles, which operate in discontinuous mode, do not place your hands under the water outlets. By following these procedures with the recommended KRUPS products, you ensure a machine in perfect condition, excellent coffee quality, and compliance with the 2-year warranty.

Question 8

How to solve the problem of the cup filling to the brim when preparing an espresso with the KRUPS EA8100 machine?

Accepted Answer

If your KRUPS EA8100 machine fills the cup to the brim when preparing an espresso, the problem usually comes from an incorrect water volume setting or a blockage in the coffee distribution group. Here’s how to effectively resolve it.

Adjust the water volume for espresso

The amount of water for an espresso should be between 30 and 70 ml depending on your preferences. To adjust this volume, use the coffee volume rotary knob located on the control panel during preparation. Press and hold the espresso button: the coffee flow will begin. Release as soon as the amount of coffee in the cup is to your liking. This setting will be saved for future espressos. Do not exceed 70 ml for an espresso, as this would prevent overflow.

Adjust the height of the coffee outlets

Check that the coffee outlets are not set too high for the size of your cup. If they are too high, the coffee may splash and overflow from the cup. You can lower or raise the coffee outlets according to the size of your cup for better pouring control. Place a cup under the outlets and check the flow before starting the preparation.

Empty the grounds collector

A full or improperly positioned grounds collector can disrupt the coffee flow and cause overflow. The machine alerts you when the collector reaches its capacity of 9 coffees. Remove and completely empty the coffee grounds collector. Ensure it is properly clicked into place until you hear a click; otherwise, it may misalign and block the flow.

Clean the distribution group

If the problem persists after these adjustments, coffee residue or scale may be blocking the distribution group. Start an automatic cleaning cycle of the machine: open the maintenance hatch, insert a KRUPS cleaning tablet (XS3000) into the cleaning chute, then press the CLEAN button. The machine will perform a cycle of about 13 minutes that will fully clean the internal circuits. If descaling is necessary (the machine will alert you with the CALC indicator), also proceed with a complete descaling using a KRUPS descaling product, which takes about 20 minutes.

Check the grind size

A very fine grind can slow down the flow and create abnormal buildup. If after all these cleanings the problem persists, try adjusting the grind size setting to a slightly coarser grind. Gently turn the grind size adjustment knob without forcing it, then test a new espresso. This action will allow the coffee to flow more freely into the cup.

Question 9

3. Flashing water reservoir light

This light generally indicates that the water reservoir is empty or improperly positioned:

Check that the reservoir is filled with fresh water.
Ensure that it is correctly inserted into the machine.

4. Flashing coffee light

This light may indicate a problem related to the coffee grounds or the brewing group:

Empty the coffee grounds container if it is full.
Clean the brewing group to avoid blockages.

General tips

After checking the above points, restart the machine to see if the problem is resolved.
If the light continues to flash despite these actions, it may be a more complex technical issue requiring specialized assistance.

Question 10

Why does my KRUPS EA8100 coffee machine not have a screen and how does this affect its use?

Accepted Answer

The KRUPS EA8100 is designed without a visible display screen: this is a design choice that simplifies the interface by replacing a digital display with an intuitive system of indicator lights and physical buttons. This approach makes the machine more compact and straightforward to use.

The machine uses a system of indicator lights to communicate its status:

Power Indicator: Steady when the machine is ready to operate, blinks during preheating
CLEAN Indicator: Blinks after about 300 preparations to signal that cleaning is necessary
CALC Indicator: Blinks to indicate that descaling is necessary (depending on water hardness)
Fill Water Tank Indicator: Lights up when the water level is insufficient
Empty Grounds Indicator: Indicates that the coffee grounds container is full

The absence of a screen does not affect the machine's capabilities as all settings are made through combinations of buttons or by using the grind fineness adjustment rotary knob (to be turned only during operation, to the left for finer, to the right for coarser). Advanced settings such as water hardness or temperature are accessible by pressing certain buttons with the machine unplugged.

For maintenance procedures without a screen: Press the corresponding button to start cleaning (CLEAN) or descaling (CALC) — the indicator changes from blinking to steady, confirming the program activation. The machine emits beeping sounds (notably a beep every 10 seconds at the end of descaling) to guide you. For cleaning, press once; for descaling, the tank must be filled with lukewarm water up to the CALC line marked on the side.

Daily use is simple: press the power button, wait for the preheating indicator to stabilize, then select your drink (espresso, normal, or long) by pressing the dedicated buttons. The machine signals you with the indicators when to empty the grounds container or fill the water tank, allowing for intuitive use without relying on a digital display.
