Eine ECAM 44.360 gibt es nicht.

 

[Ano]

Eine ECAM 44.360 gibt es nicht.

Muss ein ECAM 44.660 sein wahrscheinlich...

 

[Richard-53]

ECAM 44.660.Das vermute ich auch sollte aber korrigiert werde für alle die später danach suchen.

You say you have replaced the original board. What 52... number does it have?
And what is the number of the new board?
Thanks!
Furthermore, please start with uploading the firmware you have on your boards - if they have not been uploaded yet here ;-)

Hello.
Also, man bring me a coffeemaschine with changed powerboard. He have caffeemaschine in service, maschine have problem in PSU, so technik change old power board by new one.
After 50 cup of coffee grinder stop working.
Now i think, that can be any Bug in code in MCU, because i record any other firmware and I try if Power board working, everything work well.
Problematic board have code:
5213221081
Sorryy, its model Ecam 44.660
I can upload firware from this board if its need.

 

[Ano]

I can upload firware from this board if its need.

That would be nice
Plus some pictures of the power board if possible.

 

[JozefG]

That would be nice
Plus some pictures of the power board if possible.

But i dont know if its OK, because i have there problem with the grinder

The firmware ("Program Data") cannot go corrupted as far as I know. As it is 'read only' to the machine.
So the only problem can be in the "EEPROM Data", or in the hardware of the machine or the displayunit.
So you can upload it with confidence ;-)

Therefore I asked if the original board has the same number as the replacement board: there could be a problem with software incompatibility in theory. However, if that was the case you should be able to make another 50 cups of coffee after erasing the EEPROM Data memory. So I don't think you have a software problem but a hardware problem in your machine.

Yes, its very interesting.
Because when I give to this powerboard another program hardware work well….
Very interesting…

here is a dump file for delonghi ecam 44.660

here is a dump file for delonghi ecam 44.660

Very nice! A last question, triac TY9 is that a T43570 with R44=82Ohm, or is it a T40570 with R44=270 Ohm?
Thanks!

...coffeemaschine with changed powerboard.
.................Now i think, that can be any Bug in code in MCU................
..............Problematic board .........

...a series of mistakes, and wrong conclusions...
The replaced electronic board is fully functional, no errors in the software, it just looks for the specific hardware, and when it gets the wrong information, it accumulates errors and stops working. When you are sure that the hardware version of the new electronic board matches the hardware version of the old electronic board, then you can afford to change the firmware with the one written for this coffee machine.
I don't like these FRANKENSTEIN. They will also confuse the next technician who will repair the machine.

Hi. Is there 270ohm and T43570 Triac. Triac is drive from MCU by Inverter HC14 also there is ok T43570 with 35mA gate current. When MCU drive direct from own pin there is use T40570 with 5mA gate current.
This triac is designed for cup heater, but this maschine havnt it.

Hello, i understand all what you want to say.
I am working as electronic designer as electronic hardware, and software too.
This can be right any bug in code.
Because, i call with man who bring me maschine, and he say, that he bring maschine to service with the same problem before. They only change power board for new one with the same code. Next they give him maschine as repaired. As I wrote prewious, he made 50cup of coffee and mistake/defect with grinder is back.
Also this is the reason, because I think that this power board with code 5213221081 have software bug.
I want to try 5213218051 wich is older as 5213221081 and this is reason why I ask to this forum about it.

If I flash different firmware for whatever reason on a customer's machine, I remove the original sticker from the pcb. And put on my own sticker stating the DeLonghi number + SW version that I put on it. To avoid confusion.
(why do I flash with a different software version? If the MCU is fried and I only have an earlier or later SW version, and no dump of the original version)

 

[Ano]

Hi. Is there 270ohm and T43570 Triac.

Are you sure? I've never seen this combination on a DeLonghi pcb. It's always EITHER a T43570 with R44=82Ohm, OR a T40570 with R44=270 Ohm. Maybe you can post a zoomed in picture of this part of the pcb? Thanks a lot in advance!

... have software bug ...

We can continue the dialogue ... but I have a big request. Do not use " software bug"
it's an excuse for those who can't deal with a hardware problem. You don't think that Delonghi will release a version with such a stupid error ... to block the machine after 50 coffees ...

... I am working as electronic designer as electronic hardware, and software too. ...

I am very impressed with you... And I've had some success writing programmer for controllers... but that's off topic.
Тhere are some hardware differences in the different versions of the electronic boards, which at first glance are the same, and the differences are difficult to notice. There are electronic boards with the same hardware version, and with different resistor-jumper configurations. There is a reason and I'm sure it's not in the software. Find which board with which number corresponds to your machine and start from there ... don't pay too much attention to who put what and what they replaced, overwrote, flashed ... basically they killed the machine, Your task is to make it like it was before as bought from the store.

Hi @JozefG , could you please check it / post a picture? Thanks!

Hallo,

bei meiner Maschine DeLonghi Magnifica ESAM 03.120.S EX-1 blinkten die 4 Warnleuchten nacheinander, nachdem ich im Testmodus wo dagegengekracht bin. Der Testmodus funktionierte allerdings noch. Ich hab die Platine mit Code 5213211641.
Mir wurde gesagt, der PIC wäre neu zu flashen.

Gesagt getan: Mit dem hex file von #13 hier (esam03-120s_sw1_1_delonghicode_5213213691) lief die maschine wieder normal - obwohl der code nicht ganz exakt übereinstimmt.

Den Fehlerhaften dump hab ich vor dem programmieren ausgelesen und als Anhang hochgeladen. Achtung, der code wird vermutlich zu einer defekten Maschine bzw. zu dem oben genannten Zustand führen...

Flashen mit eine andere Version wuerde ich nicht anraten. Loeschen von EEPROM Data von deine eigene Dump ist genug, dann soll die Maschine auch wieder funktionieren.
