Hallo.

Zunächst einmal verzeihen, wenn ich die deutsche Sprache ist nicht angemessen, da ich Spanisch am und schreiben verwende ich den Google Übersetzer zu tun. Ich hoffe, wir verstehen.

Ich nehme diesen Thread Für mein Problem, wenn nicht gleich, ist ähnlich.

http://www.saeco-support-forum.de/v...ande-rote-led-dauerlicht-platinenschaden.html

Zuerst möchte ich alle Beiträge, die Sie machen weiter danke Mit diesen Maschinen große Kaffee.

Macht mehr als ein Jahr und berät mich auf ein Problem, das ich in den Topf hatte, ist das Modell SP18 Wien, und hatte mit der Platine zu ändern. Jetzt fühle ich mich ein ähnliches Problem. Ich denke, in diesem Fall von dem, was ich lese in diesem Beitrag, könnte die IC werden, und auch, dass meine Kraft hat R14 verbrannt.

Ich fing an, die Kaffeemühle zu verpassen. Beim Versuch, einen Kaffee anstatt der ersten Stufe der Kaffee mahlen, wenn Sie ging direkt auf den Deckel der Kaffeesatz und folgte der Rest des Prozesses zu tun, aber zumindest funktionierte es.

Zuerst dachte ich, es war die Mikro-Schalter, der unter dem Elektromagneten, dass der Deckel des Kaffeesatz öffnet ist, aber nach der Prüfung war es in Ordnung.

Dann, als ich sah, stieg Schaltung R14 verbrannt war, wie war der alte Kreis hatte ihn verändert, sah ich, dass der Widerstand bei 1 kOhm und ich änderte es, aber wenn ich schaltete das Gerät, das 2 Sekunden stand er und behielt nur Grünes Licht für Netzschalter. Er war zurückgekommen, um den R14 zu brennen.

Ich habe in diesem Beitrag, wenn es der IC nicht passiert, lesen, aber wollte es genau, wenn das wahr ist weiß, wird nicht eine neue (die man durch dieses Update verkauft) um, und es wäre aus einem anderen Grund sein, oder die setzen und zu brennen.

Gibt es eine Möglichkeit, es zu testen?.

Vielen Dank im Voraus, vor allem für ihre Geduld bei der Lektüre dieses und versuchen zu verstehen.

Greetings. Javier

P. S. Ich habe mechanischen und elektronischen Kenntnisse.

Dank für die Beantwortung. Mein Englisch ist genauso schlimm wie Deutsch, aber ich werde es versuchen. Ich schreibe es in beide Richtungen.

Auch ich brauche in Spanisch schreiben, versuche ich zu verstehen.

Das grüne Licht bleibt an, nachdem Sie bewegen Sie den Kaffee-Gruppe für zwei Sekunden und gestoppt und verriegelt bleiben.

Greetings.


Thanks for answering. My English is just as bad as German, but I'll try. I will write it both ways.

Nor need I write in Spanish, I try to understand.

The green light stays on after you start moving the coffee group for two seconds and stay stopped and locked.

Greetings.

I write in English.

Hello.

I guess this thread for my problem, if not identical, is similar.

http://www.saeco-support-forum.de/v...ande-rote-led-dauerlicht-platinenschaden.html

First I would like to thank all contributors that make these machines continue to function and produce a great coffee.

More than a year since I visited this forum and advised me with a problem I had in the machine, model SP18 Vienna, and had to change the circuit board. Now I have a similar problem. I think in this case from what I read in this article could be the IC as well have burned the resistance R14.

He started to not work the coffee grinder. When I wanted to make a coffee, instead of the first stage was to grind the coffee, if you went straight to open the lid and ground coffee and continued with the rest of the process to end, but at least it worked.

At first I thought it was the micro-switch located on the solenoid that opens the lid of the coffee grounds, but later found it was fine.

Then I saw that had burned R14 resistance of the circuit. Since I had an old circuit, I saw that the impedance was 1000 ohms and changed, but when I turn on, two seconds and was stopped only green light switch. He had returned to burn the R14 and not working at all.

I have read in this post that the problem comes from the IC, but I want to be sure if I buy and damage the IC again by another circumstance.

Is there any way to test?.

Thanks in advance, especially for their patience in reading this and try to understand.

Greetings. Javier

Hi,

R14 ist part of a microswitch ciruit ....... X_8720.HWD_Vienna-Markup_aa_
The circuit line from JP14 to the resistor R14 runs pretty close to the high voltage lines of the grinder.
If the resistor R14 ist broken, there probably has been a high voltage cross over from the grinder. The result ist a burned resistor R14 und most often a broken microprocessor.
Look for burned spots in the vicinity of the big 4Ohm7-resistor and the noise suppressor coils L1 and L2.

Harry

Thanks for the reply. I will check what you've told me, to see if I find something.

Hello.

I've been watching, even with a magnifying glass, and I have not found anything capable of being burned, or electronic component or circuit court, except the R14. L4 and L5 coils are continuous, and the 4ohm7 also okay.

Is there any way to check the electric motor of the grinder? I know that going to 230 V. DC, and I've seen have a plastic covered component, but do not know if such a filter capacitor or diode. ¿I can connect 230 v. network directly, or am I crazy?.

Thanks for everything.

P. S. By the way, I just saw that commented on the coils L1 and L2, where are they? Or are the L4 and L5?

Hi,

Yes there is. You need about 200 VDC to connect th grinder to this voltage source.
If you have the proper spare sparts, rebuild the Saeco circuit on a test board ...... X_Circuit-Grinder-Markup_aa_
You are right, the suppressor coils on the M5AV1-8 carry the abbreviations L4 and L5.

Ok.

I've done the circuit. My question is, if the symbols leaving 4ohm7 resistance and (-) rectifier diodes, are the coils L4 and L5. Is it this?.

 

[hmilbradt]

Hi,

That's rights. These symbols show L5 und L4 on a M5AV1-8 Vienna board.

Thank you for answering so fast. I'll try tomorrow morning, when no one, for when I plug in and fire home.

If it works the electric motor of the grinder, then where do I follow? or directly I.C. is a problem and must be changed?. If R14 is burned by a short, not again spoil the IC or the short is in the I.C.?

Sorry so many questions and thanks for the answers.

Well, I checked the electric motor of the grinder and it works perfectly.

I am now, as they say here, more lost than an octopus in a parking lot.

What do I have to do or check now?.

Hi,

The resistor R14 is broken because it received a high voltage that even reached the ADC-Pin7 of the microprocessor. There is a high possibility that the port-electronics of this ADC-Pin7 inside the CPU are faulty.
Look for a replacement CPU .....

Ok.

But then we go back to what led me to write this post, and sorry to insist, how do I know that changing the IC (CPU) and the resistance R14, it will not happen again, and again will burn if you get high voltage, as this problem is not solved?

Not to be rude to so many questions and insistence and above is compounded by language, but what makes you get high voltage in the R14? I understand that it is the CPU that first burned the R14 and it worked (without grinder) and when I said the R14, was re-burn and then (as you mention before ADCpin7) the CPU.

Thanks for so much patience with me. ( )

Hi,

Most incidences of burned resistors R14 or R15 reported in the Forum showed a damaged CPU. The resistors used by Saeco are able to sustain a load of 0,25 W which is sufficient in a 5 VDC signal circuit. In many cases the members found burned spots below the big 4Ohm7 resistor positioned in the grinder power circuit. The signal lines of JP14 run pretty close to the DC power lines of the grinder. Dust saturated with moisture creates voltage cross-overs that could burn the board and resistors.

Sorry, I am not able to diagnose your exact problem with a 100% certainty.

Harry

After reading your comments, I turned 4ohm7 resistance, and have seen this:

 

[atabasco]

I desold 4ohm7, and I've seen this. It's what you said and had not managed to see:

 

[atabasco]

If you think well, to avoid passing high voltage near there, I will vary the position of the coil L4, as the copper circuit passes through the site:

 

[hmilbradt]

Hi,

You have found the reason for your damaged resistor and microprocessor.
Clean the burned spot carefully prior to soldering the spare parts.

regards
Harry

 

[atabasco]

I will ask the I.C. to replace it. Meanwhile, put the I.C. old plate is in a database to see if it works and if so, to have parts.

Thanks for everything and forgive my insistence, in the end all of your comments were true and if the latter had checked it at first, would have saved time and effort.

It let you know when you have it resolved and working and sorry for the language, because it could bring my little experience in the forum.
