Je zet het apparaat aan. Als hij is opgestart, kies je een product. Normaal gesproken begint hij dan meteen met bonen malen. Nu blijft het stil (dus niet het aanlopen van het maalgedeelte) na een paar seconden gaat het apparaat gewoon door en hoor je de 'aanstamper' (ik weet niet hoe dit onderdeel heet) naar beneden komen. Op dat moment heeft het apparaat door dat er niet genoeg koffie aanwezig is en breekt hij het proces af.

Vanaf dat moment verschijnt er trouwens ook de melding op het scherm 'bonen vullen' terwijl die er gewoon inzitten.

Is er misschien nog iets wat ik zou kunnen proberen?

I found mentions of the motor not being properly aligned.

The official FAQ states: The motor might not be in the correct position. Check if the water tank is filled and if the drip tray is in place. Turn the appliance OFF and then ON again. Then simultaneously press the button for My-Coffee and the on/off button for more than 2 seconds. The motor will move into the correct position. Insert the brewing unit again and check that it is correctly locked in position.

However, this proposed solution did not reset the motor position in my case.

I found that the locking handle of the brewing unit moves a metal lever.

This metal lever engages a button in the machine.

By carefully pressing this button (i used the handle of a small spoon), the motor reset to the correct position.

Long story short: I don't have a question, and just wanted to post this here for future reference.

edit

I managed to get it working but it’s started again. It grinds, sounds like it producing coffee, but no coffee is produced, water is in the tray and underneath the unit with very wet grounds in the bin. I’ve tried changing the grounds finer and courser. I’ve tried using ready ground coffee it’s doing the same. I’m googled eyed with googling for answers.

Was working perfectly until a few days ago when the 'Air in the system' icon appeared on the display. I checked the manual and pressed the bean button (coffee strength) to purge air from the system.

The pump runs for about a minute and when the process completes, the icon remains illuminated. I followed this same procedure multiple times but the drip tray just fills with clean water.

I read a post somewhere online that said a likely (and common) culprit was a failed drainage valve.

After following the iFixit guide, I thoroughly cleaned the main unit and looked for any failed/ broken parts. Everything looked fine.

I replaced the drainage valve with a new Melitta part, lubricating all of the valve gaskets and the white plastic actuator in the back of the brewing unit area with a light coat of silicone grease. The actuator was installed using the markings on the cover as advised in the guide. No cables were disconnected or damaged.

Upon reassembly and after a factory reset, the same issue persists.

I've also followed the iFixit guide to dismantle and thoroughly clean the brewing unit and see if a gasket had failed or if there was a blockage. There wasn't - everything looked fine.

Can anyone help?

ADDITIONAL INFO:

Unit is regularly cleaned with Melitta products and has been descaled with Durgol descaler.

With the brewing module side cover off, the startup/ shutdown procedures seems to still move the parts of the brewing module.

Spoke to the Melitta engineer at Coffee Classics (UK) and he's suggested that I replace the flow meter.

The engineer has speculated that if replacing the flow meter doesn't resolve the issue, it could be the logic board which would make the unit uneconomical to repair.

Success! It was the flow meter. Now drinking my favourite brew again.

After shipping my coffee machine Melitta Caffeo Barista in a plane, it stopped working. I turned it on and I realize the rinsing program was not pouring water on the front but rather realising steam from the top and dropping water from the bottom of the machine. I have opened the machine and realize that the water is leaking on a pipe X-connection in the top of the coffee machine. I have a video and picture of it attached. Any help with how to fix it it is really appreciated!

Thanks!

Recently, the machine has been repeatedly indicating that I should refill beans, but this is filled with beans. I changed the beans and wiped out the container, grinder inside of machine but the problem persists.

Or when Refill beans is on the screen and we press the button to do coffee it did it few times

We tried to soak the brewing block just in water for a,few,hours, we can get 1-2 cups of coffee after that and the issue starts again.

What is interesting when we put in a ground coffee it works without any problems.

What could be the cause?

I would be very grateful about tips: what seems to be problem or who can fix it?

Is this controlled by a micro switch?

I am troubleshooting a professional coffee machine (Melitta C35) control board based on the Freescale ColdFire MCF5232CVM100 (BGA package). The system is currently stuck at the initial "Please wait" screen and does not proceed to the main menu.

Hardware Details & Measurements:

·         MCU: MCF5232CVM100 (ColdFire V2 Core).

·         Flash: cFeon EN29LV160 (TSOP-48).

·         Power Rails:

o    VDD (Core): Measured 1.6V on the micro-capacitors surrounding the MCF5232.

o    VDDIO/Periphery: Stable 3.3V found across the board.

o    Analog/Other: 5V rail is present.

·         RTC Battery: Measured 3.29V (stable).

·         Debug Interfaces: The board provides a standard 26-pin ColdFire BDM header AND a 10-pin (2x5) Mini-BDM connector.

·         Service Port: External 9-pin RS-232 (DCE, Female).

Symptoms:

1.    On power-up, the display initializes and shows "Please wait".

2.    The board has a Reset button that toggles the 3.3V line, but the MCU remains in the same "Please wait" state after reset.

3.    I measured -5.6V on the TX pin of the RS-232 port, which indicates that the line driver is powered and the UART is likely initialized by the bootloader.

Questions for the community:

1.    Given that the display shows "Please wait", is it safe to assume the MCU has successfully initialized the FlexBus and started executing code from the external Flash?

2.    What are the typical reasons for a ColdFire V2 to hang at this stage? Could it be a checksum mismatch in the Flash or a timeout waiting for a peripheral (I2C/SPI)?

3.    Does the presence of both 10-pin and 26-pin BDM headers imply any specific debugging priority? Is one more suitable for a USBDM interface to dump the cFeon Flash?

4.    Are there any known "trap" states or Double Bus Fault indicators I can check via the BDM pins without a full debugger?

Thank you, Alex
