My deLonghi failed by leaking from this connection (after years of operation). After a failed attempt with what I was told was an OEM o-ring, I successfully repaired it with a "Silicone O-Ring, 7mm OD, 3mm ID, 2mm Width, VMQ Seal Rings Gasket" from Amazon. (I used a dental pick to pull out the old ring.)

I did not have the magnetic project mat, but instead I stuck loops of blue painter's tape on the table, wrote the step number on them in sharpie, and stuck the screws/covers for the corresponding step on them.

I had issues in reassembly - the lever for the ZIF socket was missing. I think it came off with the tape. I found the lever, but it was way too small for me to reattach (I couldn't hold it well enough with the tweezers and wasn't sure where the hinge pins went).

The computer did not recognize the battery or recognized it with errors (if I got the cable just right) without the lever.

My solution was to cut a tiny bit of electrical tape and put it on the back of the ribbon cable to make it thicker. This gave it enough traction to stay in the socket and pushed the ribbon onto the contacts.

Thanks - the second hand fell off of my kid’s lego watch. It still worked, but it was important to him that the second hand moved. The trick in step 4 to get the stem off was the crucial thing that I was missing.
