quick tips

  • Only adjust the grinder while it is actually grinding

    The EA8108 has a mechanical grind-adjustment dial inside the bean hopper. Turn it to the left for a finer grind and to the right for a coarser grind. A finer setting generally produces a stronger, creamier espresso, while a coarser setting can help if coffee is dispensing too slowly.

    Crucially, only move the adjustment while the grinder is running. Never force the dial while the grinder is stationary. Make small changes and brew again before deciding whether another adjustment is needed.

  • Use the correct button and volume combination for stronger coffee

    The EA8108 has separate standard coffee and strong coffee buttons, while the rotary control determines the amount of water delivered.

    The machine is designed for approximately 30–70 ml espresso and 80–220 ml coffee/lungo. If you want a larger drink but still want it strong, avoid simply increasing the water volume excessively. The manual specifically suggests making a larger strong coffee as two smaller brewing cycles—for example, two 70 ml cycles for a 140 ml drink.

  • If coffee starts running very slowly, check the grind before assuming the pump has failed

    An EA8108 producing coffee only in a trickle may simply be grinding too finely. Move the grinder slightly towards a coarser setting while it is grinding and test again.

    Also run a coffee-circuit rinse. On this machine, a normal coffee rinse sends approximately 40 ml through the coffee circuit and can be started using the rinse/maintenance control when the machine isn't requesting CLEAN or CALC maintenance.

  • Purge the steam nozzle immediately after frothing milk

    Milk is frothed directly with the removable steam nozzle rather than through an integrated milk carafe. After frothing, place a container underneath and run steam for around 10 seconds to clear milk remaining inside the nozzle.

    This matters on the EA8108 because dried milk can block both the steam outlet and the small air inlet holes, resulting in weak steam or poor foam.

  • Don't ignore the grounds-container light after refitting the container

    The grounds container has to be completely emptied when removed. Importantly, the EA8108 can continue displaying its warning if the container isn't pushed fully home or if it is put back in less than four seconds after removal.

    If you've emptied the container but the warning remains, remove it again, wait at least four seconds and reinstall it properly. The grounds container holds approximately nine coffees.

  • CLEAN and CALC are different maintenance requests

    A flashing CLEAN light means the coffee system is requesting its automatic cleaning programme. A flashing CALC light means the machine requires descaling.

    When CLEAN and CALC flash together, the EA8108 is requesting its separate long-rinse programme. Don't treat every maintenance light as a request to descale—the light combination tells you which programme the machine requires.

FAQ's

  • Why is my Krups Essential EA8108 coffee weak?

    First select the strong-coffee button rather than standard coffee and reduce the programmed water volume if the drink is too diluted.

    If extraction is still weak, adjust the grinder one step finer while it is actually grinding. Avoid oily, caramelised or flavoured beans because the EA8108 manual specifically advises against them.

    For a large strong coffee, use two smaller brewing cycles rather than pushing excessive water through one coffee puck.

  • Why is my EA8108 steam nozzle not frothing milk properly?

    Start with recently opened pasteurised or UHT milk. If steam is present but the milk doesn't foam properly, remove the steam nozzle and clean it with water, a little non-abrasive washing-up liquid and a brush.

    Check the small air inlet holes carefully. If dried milk has blocked them, clear them using the supplied needle. The removable steam nozzle should not be put in the dishwasher.

    After every milk drink, running steam for around 10 seconds helps prevent milk drying inside the nozzle.

  • Why won't my EA8108 make coffee when a warning light is showing?

    Look at which indicator is illuminated. The machine can prevent coffee preparation if the water tank needs filling or the grounds-container/drip-tray warning is active.

    Check that the water tank is filled and correctly seated. Empty and correctly refit the grounds container and drip tray. If CLEAN or CALC is flashing, the machine is requesting its corresponding maintenance programme.

    The EA8108 doesn't rely on conventional numbered error codes; its combination of illuminated and flashing LEDs is its diagnostic system.

Warning Lights & Fault Indicators

  • Grounds/drip-tray light

    Empty the coffee-grounds collector and drip tray. If the light stays on after you've done this, check that the grounds container is properly fitted and wasn't reinstalled within four seconds of removal.

  • Grounds/drip-tray light

    Empty the coffee-grounds collector and drip tray. If the light stays on after you've done this, check that the grounds container is properly fitted and wasn't reinstalled within four seconds of removal.

  • Water-tank light

    Fill the water tank and check that it is correctly positioned. The same warning can appear when a coffee cycle has been interrupted because the machine ran out of water.

  • CLEAN flashing

    The automatic coffee-system cleaning programme is required.

  • CLEAN illuminated continuously during maintenance

    The cleaning programme is currently running.

  • CALC flashing

    The descaling programme is required.

  • CALC illuminated during maintenance

    A descaling cycle is underway.

  • CLEAN + CALC flashing:

    The machine is requesting a long rinse.

  • CLEAN + CALC illuminated

    The long-rinse programme is underway.

  • Warning lights flashing simultaneously

    The manual identifies simultaneous flashing as an operating fault/anomaly rather than a normal maintenance request. If normal checks, correct tank/container positioning and restarting do not clear it, the machine may require further diagnosis.

  • Red lights flashing one after another

    This occurs while the machine is shutting itself down and isn't normally a fault.

  • How to Clean the Milk / Steam System

    The EA8108 doesn't have an automatic integrated milk system. Milk is textured using its removable steam nozzle, so keeping this assembly clean is particularly important.

    After frothing milk:

    1. Remove the milk from beneath the nozzle.
    2. Put an empty container underneath.
    3. Run steam again for approximately 10 seconds to purge residual milk.
    4. Allow the nozzle to cool before handling it.
    5. Remove the steam nozzle.

    6. Wash it using water, a small amount of non-abrasive washing-up liquid and a brush.
    7. Rinse and dry it thoroughly.
    8. Inspect the air inlet holes for dried milk.
    9. Use the supplied cleaning needle if an inlet is blocked.
    10. Refit the nozzle securely.

    Don't put the steam nozzle in a dishwasher.

    The EA8108 limits individual steam-production cycles to approximately two minutes.

  • How to Adjust the EA8108 Grinder

    Open the bean-hopper lid and locate the grind adjustment control.

    Turn left → finer grind

    This can increase extraction resistance and produce a stronger, creamier espresso.

    Turn right → coarser grind

    This allows water to pass through the coffee more easily and can help if dispensing has become excessively slow.

    The critical EA8108 rule is:

    Only adjust the dial while the grinder is operating.

    Don't force the adjustment when the grinder is stationary.

    For fault finding, change it gradually rather than moving immediately from one extreme to the other. Brew another coffee and assess the flow before making another change.

  • How to Clean the Coffee System

    The EA8108 automatically requests its full cleaning programme by flashing the CLEAN indicator. The manual states that this is typically requested after roughly 300 coffee/espresso preparations.

    You'll need a cleaning tablet and a container holding at least 600 ml.

    When CLEAN flashes:

    1. Start the cleaning programme using the maintenance control.
    2. CLEAN becomes steady while the relevant action lights flash.
    3. Remove, empty and clean the grounds container.
    4. Empty and clean the drip tray.
    5. Fill and reinstall the water tank.
    6. Put a container of at least 600 ml beneath the coffee outlets.
    7. Open the maintenance hatch.
    8. Insert the XS3000 cleaning tablet into the cleaning chute.
    9. Start the cycle.
    10. Allow the machine to complete the automatic cleaning and rinsing sequence.

    The cleaning stage takes approximately 13 minutes and includes several separate water deliveries.

    Once completed, the CLEAN light goes out.

  • How to Descale the EA8108

    A flashing CALC light indicates that the machine has calculated that descaling is required. The interval therefore depends partly on water hardness rather than simply a fixed number of months.

    The complete programme takes approximately 20 minutes and requires a container of at least 600 ml.

    If a Claris Aqua Filter F088 is fitted, remove it before descaling.

    The EA8108 programme has three main stages: an initial descaling phase of approximately 8 minutes, followed by a rinse of around 6 minutes, then a final rinse of around 6 minutes.

    The machine uses its lights and audible beeps to tell you when to empty the waste container, rinse/refill the water tank and continue to the next stage.

    Don't interrupt the programme. The manual notes that disconnecting the machine during descaling can cause the programme to restart from the beginning.

  • How to Use or Change the Water Filter

    The EA8108 can be used with the Claris Aqua Filter System F088 cartridge.

    The cartridge fits inside the water tank. When replacing it, remove the tank, take out the old cartridge and fit the replacement securely in its position at the bottom of the reservoir.

    After fitting a new cartridge, the water circuit needs to be correctly primed/rinsed before normal coffee preparation.

    Remember to remove the filter cartridge before running the EA8108 descaling programme.

  • Krups Essential EA8108 Specifications

    The EA8108 is a compact automatic bean-to-cup espresso machine using the Compact Thermoblock System, a 15-bar pump and an integrated metal-burr coffee grinder. It prepares ristretto at approximately 20–30 ml, espresso at 30–70 ml, and coffee/lungo at 80–220 ml, with a two-cup function that performs two complete brewing cycles. Coffee strength can be selected using the standard or strong coffee controls, while drink volume is set using the rotary volume selector. Milk drinks are prepared manually using the removable steam nozzle. Maintenance is communicated through dedicated water, grounds/drip-tray, CLEAN and CALC indicator lights rather than a text display or numbered error-code system.
