Hallo habe jetzt wieder das Problem das die Maschine Satzbehälter leeren anzeigt, ist aber alles sauber. Kann mir jemand helfen das wäre schön

Hallo @Wolfgang Lump ,
ist die kleine extra Kammer in der Abtropfschale auch frei von Schmodder und ist sauber und trocken?
Gibt es dazu evtl. eine Vorgeschichte?

Hallo, ich habe das gleiche Problem mit unserer Xelsis hd8942/11: Satzbehälter leeren, obwohl bereits leer und auch lange genug gewartet damit die Maschine es merkt. Weiß jemand, wie die Maschine überhaupt feststellt, dass der Behälter voll ist ? Was kann man tun, um die Anzeige wegzubekommen ?

 

[uhrmacher]

Reinige zuerst die kleine Wassertasche in der Tropfschale, wenn da alter Schmodder drin steckt denkt der kapazitive Sensor in der Türe dass der Behälter voll Wasser steht und verlangt die Entleerung von beidem. Bringt das nix könnte der Sensor in der Türe feucht geworden sein.

 

[HeikoKaffee]

Hallo Uhrmacher, danke für deine Antwort ! Du meinst den kleinen Plastikeinsatz mit dem Runden Loch ? (unter dem Metallgitter in der Schale)

Wo sitzt der Sensor in der Tür ? Kann ich verhindern, dass er nass wird, oder ihn notfalls trocknen ?

 

[uhrmacher]

Nein, Ich meine die kleine extra Kammer in der Tropfschale( unter der Brühgruppe), welche zur Tür hin zeigt. Der Sensor sitzt unten in der Tür genau gegenüber dieser kleinen eckigen Tasche.

 

[HeikoKaffee]

Habe die kleine Kammer gefunden und gereinigt. Momentan läuft die Maschine wieder Vielen Dank !

 

[HeikoKaffee]

Zur Zeit zeigt die Maschine wieder den gleichen Fehler. Die kleine Kammer ist blitz-blank wie frisch aus dem Laden geputzt.

Beim letzten Auftreten dieses Fehlers hatte Uhrmacher angesprochen, dass der Sensor gegenüber der Kammer feucht geworden sein könnte ? Wie kann ich das kontrollieren und beheben ?

Gibt es weitere mögliche Ursachen für diesen Fehler ?

 

[uhrmacher]

Nein, dies wäre fast die einzige Möglichkeit. Schraube die unteren Schrauben in der Tür alle raus, dann kann die Tropfschale samt Aufnahme abgenommen werden und der Sensor ist dann von vorn unten in der Tür zu sehen.

No, this would be almost the only possibility. Unscrew all the lower screws in the door, then the drip tray can be removed together with the holder and the sensor can then be seen from the bottom front of the door.

I know this is old post but I have on and off the same problem.
Any idea if the sensor can be bypassed to see if this is software or the actual sensor problem?
If the sensor is disconnected should I report as cleaning needed or empty state?
There are 3 wires to the sensor, I presume + - power and logical output.
Did anyone see any post about more details what the output should be in full and empty state?
Thanks

In leerem Zustand und mit abgezogenem Kabel wird der Sensor im Testmenü mit inaktiv ( kein zu hoher Füllstand) gemeldet. Prüfe auch ohne Restwasserschale, sehr oft ist der Schmutz in der kleinen Kammer der Schale das Problem (hoher Füllstand obwohl kein Wasser drin steht).
In the empty state and with the cable removed, the sensor is reported as inactive in the test menu (level not too high). Also check without a residual water bowl, very often the problem is the dirt in the small chamber of the bowl (high filling level although there is no water in it).

Thank you very much Watchmaker! You never fail to help!
The machine is absolutely clean and dry now. Also cleaned the sensor circuit board in rubbing alcohol.
Hard to say if the problem is the board or the software.
Will do more testing!

 

[uhrmacher]

OK, in the test menu you can read the status of the sensor. That should make it easy to find the error. If the sensor reports a high filling level when the door is open, it is probably defective. The connector on the sensor can also be removed for the test, in which case no active sensor may be reported in the test menu.

Thank you!
The problem is on and off so I presume it's the sensor or the contact connector. Cleaning the connector (wire side) is not easy.
Will try using the Service menu.

 

[uhrmacher]

If there are traces of oxide on the connector, that will be the problem. The sensor is often also defective because a conductor track has oxidized right under the white connector (not visible without removing the connector).
Secure the silicone hose on the coffee spout in the door again with 2 hose clamps. There some coffee likes to run down to the sensor and cause these problems.

Yes, cleaned up everything but it's impossible to see the inside the wire connector male part.
Did the hose clamp improvement immediately I seen your previous post about it!
It is so great toy have you here with all the experience you have!

Off topic question... Did you manage to source orings in bulk somewhere? Here in Canada it costs arm and leg and you have to buy them piece by piece.

So, entered the service menu and with the sensor connected I get no change if I touch it or not.
I presume it doesn't work since the status would change to "white" in the service menu right?

 

[uhrmacher]

With a bit of skill you can pull the individual contacts out of the plug and clean them. To do this, you have to use a very pointed object to bend the small plastic catch outwards and at the same time gently pull on the cable. I buy O-rings here from Ebay dealers in Germany, usually in large quantities, then they are inexpensive.

Yes, the red circle jam should turn white when the hand is held close to the sensor board. To test, you can swap the sensor with the sensor from the water tank (rear side above the Coffee-water heater).

Will try that!
Yeah, will have to do that as well, and combine shipping since that adds lots of cost as well.
Thanks
