DeLonghi Magnifica S Smart won't power on, fuse worth checking?

[Thomas Martinez]

See some posts about DeLonghi machines dying out of nowhere. First thing people usually checks is the machine for power issues. For the Magnifica S Smart models, the fuse and PCB is located above the water tank. To access them, remove the covers from the machine.
The easiest way to test for power issue is to unplug the machine, remove the covers and use a multimeter to test the fuse for continuity. If you determine the fuse is blown, replacing the fuse will fix the issues with the machine. The hardest part of this repair is removing the covers from the machine. The machine seems to have some clips that holds the housing together that can be tricky to release. I have not encountered any screws on these moddern models so it seems like the clips are what hold the housing together.

Did mine about 6 month ago, fuse was indeed blown. Replaced it and it has been fine ever since. Getting to the housing seemed like the most difficult part though. There are clips on the sides that you have to pop to get the panel to pulling up.

if the fuse blew theresusually a short somewhere or a stuck triac. Just slapping a new fuse in without checking the pumps or heating element will pop the fuse again real quick.

wait so the fuse is the thermal one or is it like an inline glass fuse on the board? im a bit confused on which one were talking about here

Honestly for what these machines cost you'd think they'd build them so the covers comes off without a fight. Italian design my ass.
