Introduction

A common issue with the Dolce Gusto Oblo is water that leaks between the water tank connector and the water tank itself when it’s unused and has water remaining on its tanks.

In this guide we will take a look at how to open the device and replace the gasket of the water tank connector assembly.

Generic spare parts for this device can be found nowadays, most parts still available for those ordering from Europe but may be difficult to find without the reference of the spare part. Have a look to the spare part schema for this device to find the reference of the spare parts easily.

The reference identifier for the gasket of the water tank connector is MS-623712.

    • Once the back plate screws are removed, look at the top plate of the coffee machine.

    • Then detach the top plate using an opening pick or a plastic opening tool if needed.

    • The top plate if firmly maintained by clips all around its perimeter, it may require a little force to detach it.

    • Once it’s detached fully, do not remove the top plate fully for now as the power button behind the top plate is connected by wires to the rest of the coffee machine and need to be removed to free the top plate fully.

    • Locate the 2 screws securing the back plate and the front plate together. Then remove the 2 screws using a Torx TR10 screwdriver.

    • 2 Torx TR10 15mm screws

    • Once screws are removed, pry on the plastic rings on the right side of the front plate using a plastic opening tool to detach it partially (see 2nd and 3rd picture that shows how to detach the right side)

    • Then do the same on the left side.

    • Pry gently, caution not to break the plastic.

    • Then lift the front plate to detach the bottom of the front plate.

    • This may require a little force as there are some plastic clips all around the front plate, use a plastic opening tool to detach then all around the perimeter of the front plate.

    • Locate the water tank connector assembly on the back of the rest of the coffee machine.

    • Remove its gasket by lifting the gasket upwards using a spudger or a plastic opening tool or your hands.

    • The gasket is not glued and can be removed easily.

    • Then insert a new gasket in the water tank connector assembly using your hands.

    • This gasket is a lip seal, so make sure to put the new gasket in the right position as shown in the 3rd picture.

    Pas besoin d'ouvrir la machine pour cela avec un levier vous retiré le vieux et vous pouvez ré insérer le nouveau en le glissant.

    Je n'ai pas réussi à retirer le joint sans démonter la machine au moment de rédiger ce tutoriel, car il était trop sec, il était dur comme de la pierre, la machine fuyait beaucoup à cause de cela.

    Mais effectivement, avec des outils permettant l'extraction, si le joint à changer n'est pas trop dur ça pourrait marcher.

    Par contre, attention à ne pas endommager la pièce en plastique sur laquelle repose le joint.

Retour d'expérience :

Cette réparation a été assez simple, la partie la plus difficile a été de détacher la plaque avant, car elle est solidement maintenue par les attaches qui sont réparties tout autour de cette pièce et sa forme atypique complique son démontage. De même pour le remontage de cette pièce qui nécessite de faire plusieurs tentatives pour bien la rattacher.

La réparation tient bien dans le temps, il n'y a plus la moindre fuite, j'utilise l'appareil tous les jours. Un bref retour sur la durée dans le temps de cette réparation sera effectué dans environ 1 an après la rédaction de ce tutoriel. En raison du type de pièce remplacée, il est certain que cette réparation durera au moins aussi longtemps que quand l'appareil était neuf. Cet appareil obtient donc une seconde vie pour un simple joint remplacé.

Bilan de la réparation : 2,5 kg de déchet plastique et électronique évité.

Astuce : pour préserver l'environnement et avoir du bon café, il existe des dosettes réutilisables en métal pour cet appareil.
