Follow these instructions in reverse order to reassemble your device. There’s one exception: Attach the black cover (step 9) to the part that houses the electronics first. Then attach that part to the flap (step 10). After that you can mount the whole thing to the vacuum.

Make sure that the two white connectors (see step 8 and 10) are aligned properly, so that they will connect again.

Hi,

I found my Miele C3 just stopped working. this article:

https://howtofixit.net/miele-vacuum-not-…

suggested a common problem was that the electric cord pulls away from the contacts, which is exactly what had happened to my vacuum.

Your article has much better steps to disassemble the vacuum, you then need to solder the wires back on. Relatively simple.

Thanks.

Hi Richard,

Ein Tipp: Eine wichtige Schraube ist in der Anleitung oben unerwähnt geblieben. Diese befindet sich unter dem Motorluft-Auslass, wenn man den Luftfilter entnimmt. Diese Schraube sollte ebenfalls im Schritt 7 und vor Schritt 8 entnommen werden.

Der richtige Zusammenbau war bei mir tricky: Das Hinterteil wird zuallererst von hinten unten hinter den rückseitigen Aufnahmekanal für den Saugschlauch geschoben. Dann wird die zusammengebaute Schaltereinheit mit Gefühl eingesetzt. Damit dabei die Tasten an der hinteren Kante des weißen Hauptdeckels vorbeipassen, muss der Deckel mehrfach vorsichtig auf- und zu bewegt werden. Dann klickt das Schalterteil irgendwann in die richtige Position. Hier nicht die Nerven verlieren (!) - Der Miele-Sauger ist hier wohl nicht mehr ganz so reparaturfreundlich wie noch bei meinem 728er-Modell von roundabout 2005, den ich vor ein paar Tagen restauriert hatte.

Cheers - Chris
