Chosen Solution
A 110v Nespresso Inissia was connected to a defective 220v to 110v transformer, which was followed by a quick pop sound power and the Inissia will not power up after that occurred. Does the Inissia have a replaceable fuse that protects its electronics under such circumstances, and if so, how do I access and replace the fuse?
From what I can tell looking at the breakdown from Ifixit (link below), I cannot see a fuse; but, the owner’s manual I found said to check the fuse without offering a location for the fuse. I would call the Nespresso Club (info at nespresso.com), and ask them if there is a fuse in the machine itself. They may actually be talking about the fuse in the fuse box of your home, but they don’t specify. There are a few capacitors, which can also make a popping noise when they blow. From the breakdown, it looks like they made the circuit board pretty hard to access, but nothing is ever impossible. Nespresso CitiZ Teardown
From a similar machine (Citiz) I can confirm there are two fuses on both line and neutral. In my case, they wrap around the heater unit and are firmly placed onto it by two torx screws. They are therefore very difficult to service as you have to completely disassemble the machine.
The fuses are in my case 5A, 167 degC Microtemp. p.s. I realize the post is useless for the OP, but someone else might benefit from my finding.
Same problem here. I just dismantle one Inissia and pull the circuit board out. No fuse in this machine apart from a big capacitor that blown open with the surge of 220 high voltage. The circuit board need to be replaced as I do not how many components on the board are affected. Would appreciate id someone can advise me (ed.leung@shaw.ca) where I can purchase the replacement circuit board (RU 94V-0 31517 PLC=3). Thanks. Edmund
I was unable to get any answers from Nespresso. I went as far as writing to the office/designer who design that circuit but unfortunately did not get a reply. Eventually, I gave the machine back to my friend as a “cannot be fixed” item. Apparently, Nespresso machines are on sales now so it make no sense to repair something that may cost more (parts and labor) than a brand new machine.
I can confirm that the Krups Inissia does have a thermal fuse, having not long ago replaced one on mine which got it going again. If you have no power to pump but flashing lights and no sound it’s likely to be the fuse. Videos online on how to take machine apart such as at https://youtu.be/kb1JZ-VIoY4. Easier than you expect as just a few Torx 20 screws and rest is fitting components together.
