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.
