Krups Espresso Error Codes & Warning Lights Guide (EA81, EA82, EA84)

How Krups Communicates Errors

Krups espresso machines don't use a list of numbered error codes. The EA81 (e.g. EA8108) talks through lights, the EA82 (EA8250) through messages on its LCD display, and the EA84 (EA8442) through a colour touch screen. The only numbered message in the manuals we read is the EA82's "Error code XX". Krups doesn't define the numbers. Its instruction is to unplug for 20 seconds, remove the Claris cartridge and switch back on, then call Krups if it returns.

Fix 1: CALC: Run the Descaling Programme (Works About 30% of the Time)

The machine asks for descaling when enough scale has built up. That depends on your water hardness and the number of steam and hot-water cycles.

1. Remove the Claris cartridge from the tank if one is fitted.
2. Use Krups F054 descaler (one 40 g sachet) and a container of at least 0.6 L.
3. EA81: start with the button, then fill the tank with warm water to the CALC line and dissolve the sachet. It runs three phases (about 8, 6 and 6 minutes), emptying the container and refilling the tank between them. The CALC light goes out at the end.
4. EA82: Services → Descaling (about 22 minutes). EA84: the maintenance menu (about 20 minutes). Follow the screen.

CALC won't clear? Finish every phase. On the EA81, unplugging or a power cut restarts the programme from the beginning. The EA81 only lets you start descaling once it asks for it.

Time: 20-22 minutes
Cost: Krups F054 descaler
Success Rate: About 30%
Difficulty: Easy

Fix 2: CLEAN and the Long Rinse (Works About 25% of the Time)

CLEAN asks for the automatic cleaning programme with a Krups XS3000 tablet. The EA81 asks about every 300 coffees, and the EA82 and EA84 about every 360. Krups says to run it when asked to keep the guarantee, and to use only XS3000 tablets.

• EA81 (about 13 minutes): empty the grounds collector and drip tray, refill the tank, and put a 0.6 L container under the outlets. Drop a tablet into the cleaning duct under the maintenance hatch and start. After the first phase (about 10 minutes), empty the container and press again for the final rinse (about 3 minutes).
• EA82 (about 20 minutes) and EA84 (about 13 minutes): from the message or the Services/maintenance menu.

CLEAN and CALC flashing together on the EA81 asks for a long rinse (about 2 minutes). Refill the tank, put a 0.6 L container under the outlets and steam nozzle, and start it.

Time: 2-20 minutes
Cost: Krups XS3000 tablet
Success Rate: About 25%
Difficulty: Easy

Fix 3: Grounds Warning, or "Empty the Two Trays" (Works About 20% of the Time)

• Empty the grounds collector completely, and the drip tray. The EA81 and EA82 collectors hold about 9 coffees.
• Wait before refitting: 6 seconds on the EA82, 8 seconds on the EA84. If you're too quick, the warning stays on. The EA84 also has a coffee drawer: refit that first, then the collector.
• EA81: wipe the area where the drawer sits, and push the collector firmly home.
• EA84: "Empty the two trays" appears every 12 coffees, even if you've emptied them in between. That's normal.
• You can't make coffee while the grounds warning is on or flashing.

Time: 2 minutes
Cost: Free
Success Rate: About 20%
Difficulty: Easy

Fix 4: Water Warning (Works About 15% of the Time)

• Fill the tank with fresh cold water, never hot water or milk, and push it in firmly.
• EA81: the light also means a coffee cycle stopped for lack of water. Fill the tank and it continues.
• Tank full but the warning stays (EA82, EA84): check the tank is seated and the float at the bottom moves freely.
• Claris cartridge message (EA82): replace it about every 50 litres or 2 months, via Services → Water filter.

Time: 1 minute
Cost: Free
Success Rate: About 15%
Difficulty: Easy

Fix 5: Fault Light or "Error Code": the Restart Procedure (Works About 10% of the Time)

• EA81, light flashing constantly (operating fault), or EA84, "the machine indicates a fault, the software is frozen": switch off and unplug, remove the filter cartridge, wait one minute, and restart.
• EA82, "Error code XX": unplug for 20 seconds, remove the Claris cartridge if fitted, and switch back on.
• No coffee came out: the machine detected a problem during preparation and restarted itself. It's ready for a new cycle.
• If the fault returns, contact Krups consumer service: 1-866-668-0325 in the U.S., 1-800-418-3325 in Canada.

Time: 2 minutes
Cost: Free
Success Rate: About 10%
Difficulty: Easy

XP6020 and Dolce Gusto Lights

XP6020 (pump espresso):

• TEMPERATURE light flashing normally means heating. Only START/STOP works until it stops.
• Flashing fast with the pump stopped means the tank is nearly empty. Set the control to PENDING, switch off, refill and reseat the tank, switch on, and run hot water through the spout for about 20 seconds.
• Flashing fast at switch-on means the control isn't at PENDING.
• Dim light means standby after 30 minutes.

Dolce Gusto Mini Me:

• Red blinking means heating (about 40 seconds). Steady green means ready.
• Orange means descale.
• Red and green flashing rapidly means no liquid: no water, or a blocked capsule.
• Red flashing fast means switch off and check for a blocked capsule. Unplug for 20 minutes, then switch on. If it's still red, call the hotline.

FAQ

What does a flashing light mean on my Krups EA8108?

A slow flash means a task is in progress. A double flash means a two-coffee cycle. A light flashing constantly means an operating fault: switch off, unplug, remove the filter cartridge, wait a minute and restart. The CLEAN and CALC lights ask for cleaning and descaling.

What does "Error code" mean on a Krups EA82?

Krups doesn't publish meanings for the numbers. The manual says to unplug for 20 seconds, remove the Claris cartridge, switch back on, and contact the service center if it persists.

How do I turn off the CALC light on my Krups?

Run the full descaling programme with Krups F054 descaler and finish every phase. The light goes out at the end.

Why does my Krups keep asking me to empty the trays?

The EA84 asks every 12 coffees, whatever you've emptied in between. On any model, wait 6-8 seconds before refitting the collector, or the warning stays on.

What does rinse mean on my Krups?

A rinse clears the circuits, for example after the machine has been unused for a few days. On the EA81, CLEAN and CALC flashing together means it wants a long rinse (about 2 minutes). The EA84 may also run a short automatic rinse when you switch it off.
