Conclusão

In order to turn the screws of the hood to sitting very deep, again, it is advisable to magnetize the screwdriver.

Since I had more problems with my Kärcher I unfortunately have to say that the quality could be better. Shortly after the warranty period, the control unit got a crack so I also had to replace this. In addition, the spare parts prices are quite high.

Hallo Wolfgang, vielen Dank für die tolle Anleitung.

Habe noch 2 Fragen:

Was war denn nun genau defekt? Hast du das rausgefunden?

Muss man das Steuergehäuse abbauen, um den Elektrokasten zu öffnen?

Danke und Gruß

Frank

Hallo Frank,

ja, ein Plastikteil war abgebrochen, so dass sich der Schalter nicht mehr entriegeln ließ.

Ja da der Elektrokasten in der Halterung für das Steuergehäuse arretiert ist.

Gruß

Wolfgang

Hallo Wolfgang,

vielen Dank für deine Anleitung. Ich bin gerade dabei, es entsprechend deiner Anleitung nachzuvollziehen.

Hast du vielleicht noch ein Bild von dem plastikteil, das kaputt war?

Bin mal gespannt, ob ich es hinbekomme.

Hattest du dir einen komplett neuen elektrokasten geholt, oder nur das entsprechende teil?

Danke und Gruss

Frank

Es scheint bei mir, nicht der Schalter zu sein. Der funktioniert.

Weißt du wie der Ausschalter durch den Druckschalter funktioniert. Scheinbar liegt der Fehler bei mir dort und nicht an der Elektrik.

Kann leider kein Photo hochladen, sonst könnte ich dir meine Vermutung zeigen.

Gruß

Frank

Ich habe den Elektrokasten geöffnet und es hing nur der Wippschalter im Elektrokasten. Dieser hat nicht komplett geschaltet. Nachdem ich diesen ein Mal von Hand bis in die Endlage geschaltet hatte , ging es wieder. Ist vielleicht ein Versuch wert, bevor man den ganzen Kasten ersetzt.
