De'Longhi ECAM 350.55B - Infuser Attachment Issue & Solution After Descaling Process

Hello, I have a De'Longhi ECAM 350.55B coffee machine. After 2 months of using the 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?

And you hear that the brewer surprises in its place?

Everything happens just like the recorded video, https://youtu.be/8JXKxzrjqsk

If there is a guarantee, I will send it to the service, from the top and bottom switches I would suggest to start checking.

It looks more like a hall sensor to me.
The brewer stops at the top and bottom, does not try to push it by force.
However, the verification will not be easy .. I would suggest trying to replace the hall sensor. If this does not help, then the problem may be in the lift magnets.

Hello
I have the same problem and I intend to order a hall sensor. After the exchange I will write if it helped

I gave the machine for guarantees and so far there is no problem

Does anyone have a specific solution to the problem? I replaced the ompkr at home and read that a reset is needed later, but I don't know how to do it. Someone help? I suspect that it could be similar for you

Perhaps someone will find it useful.
I had a similar problem with the machine showing the general alarm message. The machine did not rinse, did not make coffee, did not turn off properly. The problem appeared right after making two coffees and turning off the machine.

I have cleaned the entire brewing unit, including taking it apart and lubricating it. Most of the dirt was under the strainer.

I unscrewed and cleaned the thermoblock strainer. This can be done from inside the machine. It was very dirty.

The last step (crucial in my case) is running hot water twice as a whole process.

If there is a problem with removing the brewing unit, you need to rotate the toothed wheel from the motor with your finger.

The fault occurred after 1.5 years of use.

Hello, has any of you found a solution to this fault "Install the infuser"? Replaced the hall sensor, unfortunately no improvement.
Please help

is the problem solved?

Unfortunately not. From what I was able to find out, after replacing the sensor, you should restart the board. There is no information anywhere on how to do this.

Replacing the Hall sensor helped so much that the brewer stops as it should. Install the brewing unit is displayed. Probably electronics.

Most often, the problem occurs when there is play in the brewing unit's carriage or it is dirty, then it misreads impulses from the hall. It is best to replace the upper and lower switches and reset the encoder

After two weeks, the return will see the same again with these backlash.

Manually, it is difficult to assess these clearances, and the sensor will have a few pulses missing and an error will be crashed. The encoder reset itself without replacing the switches should do the trick, but it's better to replace because the contacts may be overheated and not always catch

Hello friend. I have the same problem - suggest how to RESET ENCODER - I will be very grateful.

Thanks a lot. I will write if it helped.

Thanks to my friend *djszaman* - on topic.

Hello and welcome,

I see that the topic is new, so I will ask for help,

For me, the elevator goes up and starts buzzing loudly but it looks like it is reaching the very end on an open housing, but the motor is still pushing,
If I remove and press this microswitch, the elevator sets up correctly and goes down

I can't fix it

Hi

Will you share your knowledge about it
How to do it?

There are 2 options. Since the button works and the machine reacts to its pressing, maybe its handle just needs to be tightened. Or something has come under the brewing cart where there is a screw on top and preventing it from reaching the end. They are mostly crushed coffee beans.

@Dj Shaman

Hi, thanks for taking a moment. If I don't press this button, it creaks to the max, but eventually it will go down and then it crashes the "attach the camera" error. So how to do this whole encoder reset? Maybe it will help...

Tom

@gsl24 encoder reset is to restore the number of steps on the hall sensor. In your case, the brewing unit is clearly not pressing the microswitch. Only after removing the cause, you can possibly perform a reset so that the coffee machine saves new data

Hi,

You were right,

However, it was not the upper microswitch that unscrewed and the infusor itself did not reach the microswitch, after gluing the 1.5 mm thick rubber, the infusor presses the microswitch and the elevator goes down. The coffee is brewed correctly without leaking. I'm just worried that the brewer will fail after some time. Now how to do a reset so that everything works perfectly?


Regards,
Tom

You still haven't removed the cause, he should commute without gluing himself.
As I wrote earlier, grains could come up or there is still an option that the propeller unscrewed and moved it back a bit, but it's more of a mess than cleaning the propeller itself. Reset here will not change anything and maybe even spoil it, I can send you instructions on how to do it, but you will do it at your own risk, because something is clearly wrong with this drive.
I sent instructions in DM

The patent with a piece of rubber from a bicycle tube worked for me (I have a Delonghi ECAM 23.460). After replacing the Hall sensor, all gaskets, gear screws, removing all play, this message continued to pop up. I cut a small circle out of a bicycle tube and glued it to the piston element of the thermoblock that pushes the upper microswitch. After two days of digging and actually major renovation, it turned out that only a piece of rubber did the trick

@Premos replacing the hall itself without reset will not do anything, data on the number of steps is saved on the motherboard, so after replacing it had to be reset.
That's why it didn't work after this general overhaul. Most likely, it was enough to just do a reset without digging and replacing anything.

Hello and welcome,

Can we expand on the hall sensor?
How exactly does it determine the destinations of the brew unit?

Is a similar sensor a popular sensor mounted e.g. in the flap of the coffee machine door in Saeco / Philips to detect whether something is or is not in a certain place?

Therefore, I believe that it marks the place of "rest" of the brewer in the "lying" position.
Any deviation from the correct position would indicate a shift of the magnet itself.

Remember that we have two positions "standing" and "lying". This should distinguish when what is the fault. Whether it's "laying down" or "getting up".


These are my thoughts on it.

Could you please send me the encoder reset procedure? I will be grateful.

The sensor is screwed parallel to the gear pulley, in which there are four strong neodymium magnets (they demagnetized my magnetic screwdriver). A coil is clearly visible on the Hall sensor, which is excited by the magnets of the rotating pulley. I am not a service technician but an ordinary layman, but in my opinion the sensor only measures the number and speed of rotation of the pulley.

From my experience, I think that's what he said djshaman it was enough to do a reset and everything would work, i.e. the system would learn to push the piston a fraction of a millimeter higher to turn on the upper microswitch. The rubber band is still working
