I have a Nespresso CitiZ coffee machine and some water is leaking into the collection tray without passing through the coffee pod. I assume that an internal seal has worn out. How easy is to renew the seal and from where can it be sourced?

Hi @kaput43, Here’s the Ifixit Nespresso CitiZ Teardown guide that should be of some help. Here’s a link to the parts for the machine. Once you have found the problem search online Nespresso (insert part number) to get results for suppliers that suit you. Looking at the Exploded View1 pdf document at the top of the parts list it appears as though the machine is a rebadged De Longhi machine. This corresponds with the part numbers when I searched for a few parts by using the above method, as the results were also for De Longhi machines.

Probably the brewing unit needs to be replaced. Here is the guide from iFixit (in German). The spare part costs about 25€.
