    @gsl24, as @Premos wrote below, the sensor collects impulses from the magnets in the wheel and on this basis the electronics calculates when to stop the engine. Sensors are only a sensor and do not save any data about the number of steps, everything is saved on the power board. Therefore, after replacing the sensor, nothing will change, because the electronics will spin the engine according to the number of impulses stored in the memory.

    Where exactly can this rubber be glued? I will ask for a photo of the best.

    You can try to make a distance where the upper microswitch is in contact with the infusor. However, this type of failure means a problem with the drive itself and most likely the machine will break down after some time so that the drive will work but the brewing group will not move up and down. It is necessary to replace the drive, i.e. the main screw and its nut or the nut itself.

    I do not know where this microswitch is and where I should put the distance. Another issue is that the machine has a mileage of 5,000 coffees, does it make sense to repair it? The model is the same as in the title of the post Delonghi Dinamica.

    You would have to unscrew the entire housing and display mount. It's not as easy as you haven't done it before.

    What could be the costs and is it worth repairing? The machine has 5000 coffees, I don't know if that's a lot or not

    @piotrkoodziej7 Thanks for sending the instructions, however, the reset procedure is to take place in service mode, what is normal on a turned off coffee machine? I'm not sure if I'm doing it right because there is no confirmation of correct execution.

    Exactly,
    The machine continues to display "attach..."

    The encoder reset procedure should be performed from the above-sent instruction (last but one page). From what I remember, the diagnostic mode is entered on the machine connected to the network, but turned off and with the tray extended (it does not have to be removed). Then we hold the buttons shown in the manual, i.e. the four corner ones, not counting the row of buttons at the very top. SELECT TEST MODE should appear on the display. After this message appears, we put the drip tray in place and then select the test we are interested in using the buttons. In our case, it is the encoder reset, i.e. the espresso icon (first under the settings icon (gears)). From what I remember, the brewer does its up and down cycle there, etc., after which no information about the end of the procedure actually pops up. The manual says to turn on the device after such a procedure and let it perform the first rinse and turn it off.

    As for the recurring problem - I suggest disassembling the brewing unit and getting acquainted with the condition of the o-rings on the piston (yesterday I had a case that they slightly swelled and inhibited the piston from sliding out and sometimes this millimeter was missing and the problem returned.

    I replaced the Halka module and sensor and it helped. Of course, first the sensor.

    Hello, I have a similar problem in DeLonghi 22.110 - how do I enter the service mode - 3 having the switch + 1 cup + 2 cups, the machine does not enter the service mode.

    Hello, I have a De'Longhi ECAM 350.55B coffee machine. After 2 months of using the coffee machine, a message appeared to carry out descaling. I did everything as described in the user manual, after descaling the coffee machine worked properly for about a week. After this time, the message "attach the infuser" popped up. I do everything as in the instructions, but the message does not disappear, the machine does not work. What to do?
    Was it due to electronics or something else?

    I have a similar problem on the primadonna de luxe model. After taking the camera out to clean it keeps popping up the message mount the camera. Inside everything is clean and rather seemingly no play. If you can I would ask for instructions on how to do an encoder reset. Thanks

    You pull out the grounds drawer.
    Rinse - coffee strength - menu - drink menu (simultaneously)
    You insert the drawer and press small espresso.

    Due to great interest, I am providing instructions on how to properly perform this reset below.

    Enter test mode:

    The coffee machine is plugged in but turned off.
    - slide out the trays.
    - press the buttons simultaneously:
    Rinsing; aroma; drink menu and MyMenu.
    After correctly performing the above, the text TEST MODE should appear on the display. then slide the trays into place.
    Now just press the espresso button to select encoder reset.

    After everything, turn on the coffee machine using the button at the top. And let it rinse, then disconnect it from the power supply (remove the plug from the socket)

    *The machine must be clean inside for the reset to be correct.
    **After booting into reset mode, the subtitles will be in English. After restarting, everything will return to normal.

    Hi,
    Can you send some photo or more detailed instructions where you glued the piece of inner tube you mentioned.
    At my place it triggers a brewer error once in a while and I would like to react in advance.
    Thanks in advance

Topic summary

The discussion addresses the "attach the infuser" error on the De'Longhi ECAM 350.55B coffee machine occurring after descaling. The issue often relates to the brewing unit's position detection, primarily involving the Hall sensor and microswitches that monitor the brewer's movement. Replacing the Hall sensor alone does not resolve the problem because the machine's motherboard stores encoder step data, requiring a specific encoder reset procedure to synchronize the new sensor data. The reset is performed by entering a diagnostic test mode with the machine off but plugged in, trays removed, and pressing a combination of buttons (Rinsing, Aroma, Drink Menu, MyMenu) until "TEST MODE" appears, then reinserting trays and selecting the espresso icon to initiate the encoder reset. Mechanical causes include play or dirt in the brewing unit carriage, misaligned or unscrewed microswitches, or obstruction by coffee grounds preventing proper microswitch activation. A practical temporary fix involves gluing a small rubber spacer (e.g., from a bicycle inner tube) to the piston element that presses the upper microswitch to ensure contact, though this may indicate underlying drive wear requiring replacement of the main screw and nut. Users report that after reset and mechanical adjustments, the error can be cleared, but recurring faults may indicate progressive mechanical failure. Additional maintenance tips include cleaning the brewing unit, thermoblock strainer, and lubricating moving parts. Similar issues and reset procedures are noted for related De'Longhi models such as ECAM 23.450, Dinamica Plus, and Primadonna series. The discussion also highlights the importance of careful assembly, as overtightening the infuser can cause the error. Service manuals and reset instructions are shared via links and images to assist users in performing the encoder reset and troubleshooting the sensor and mechanical components.
