KRUPS EA81* EA8105 EA810507 Reset

Hello and thank you for the post with the reset!

My EA8109 without display got a new drainage valve a few weeks ago, after the reset instructions everything worked again.

Now I have the problem since yesterday that the upper piston stays up. It no longer moves down. Not even with a little "pressure". Am I doing something wrong with the reset, or is the pressure cylinder broken?

If I press down a few mm by hand, the piston returns to its original position at the end of the procedure.

KRUPS EA81* Reset with or without cleaning slide. Pomace container and water container LED flashing. Trying to change the grinder setting, grinder grinding time, grinding quantity, coffee powder quantity according to a procedure described in the forums usually makes the machine unusable. The grounds container and water container LEDs flash after restarting, no more button input possible, machine does not heat up. In a forum, an unknown forum user has described a possible RESET for all those affected. I expressly emphasize that I am not the inventor of this procedure, the credit goes to an unknown person. I am merely transferring the procedure into a readable form and adding a few more steps. I have tried it on a machine WITHOUT a cleaning slide. It works! 1. Disconnect the machine from the power supply (unplug) 2. Remove the water tank, grounds container and cleaning slide (if present) 3. Set the flow regulator to 20 ml 4. Press and hold the "strong coffee" button on the far right and plug in 5. All LEDs light up, water tank filled, grounds container, reset cleaning slide (if present) 6. Adjust the flow regulator until all LEDs have gone out (approximately middle position) 7. Place the container under the coffee spout and steam nozzle, now press the "weak coffee" button 8. Water is pumped through the coffee spout and steam nozzle, the brewing piston moves to the upper edge of the brewing chamber. The process is repeated twice. Then all red LEDs have gone out 9. Press the "weak coffee" button again 10. The machine lowers the brewing piston twice, the last time the brewing piston remains in its lowest position. When "all LEDs are flashing" 11. Unplug the machine and wait at least 5 seconds 12. Plug in the mains plug, the brewing piston returns to its original position. Machine is working again.

But, at step 3: set the dial to amount of water NOT to 20ml (minimum), but to 220ml (maximum).
Then, at step 6: turn the dial all the way down to 20ml (minimum), and then back to 220ml (maximum).

If you follow the original instruction, after the reset, the amount of water at the dial of 20ml will be much BIGGER than 20ml.

Actually, in my case, it doesn't matter where I put the dial initially, it always gives me 40ml of coffee at the 20ml setting.
I think, this is because when I fixed the water counter, which has 2 magnets, I have accidently reversed polarity of one of them, and now only 1 magnet is used, thus the double of the volume.
This is still in theory.
I will check it out whenever I'm really pissed about drinking espresso instead of ristretto.

Too everyone with a EA81x WITH DISPLAY with a "missing waste container" bricked machine after trying to follow reset instructions read on: The way to fix this is simple, and yet was impossible to find anywhere. Unplug the machine. Remove water tank and waste container. Press the ⚙ button while plugging it back in the wall socket to enter the service menu. Insert waste container back in. Press start and the should be displayed d69 and the icon to unplug the machine flashing. Unplug the machine again. Insert the water tank and plug the machine back ~ You should now be able to turn on the machine and use it normally.

Thanks
IT WORKS.

Hello, when I switch on my EA8105, a cycle starts immediately in which the piston moves a few times, the pusher wants to push the (non-existent) coffee grounds into the grounds container, but then a flashing LED indicates that the container is full. So I take the (empty) container out and put it back in and everything starts all over again. Full message, even though the container is empty.

What strikes me is that after the pusher for the coffee grounds has moved over the cylinder, there is no clicking noise. My first assumption was a mechanical problem, but I can't see anything visually (machine disassembled).
When trying to reset according to the instructions, everything works up to point 10, namely that the piston does not stop in the lowest position, but in the highest position. From point 12, when I plug the plug back in, the reset process is not completed, but the machine is stuck again in the cycle described at the beginning.

Does anyone have any idea why this could be?

Great !!! Everything is running normally again. Many thanks for this advice.
