after performing a descale on the Odea Giro, which i have done a number of times in the past. On Saturday Morning, after getting the green light and preparing to make my first coffee, the machine starts to go through the process, but then does not grind then the regular noise fades out, there is a loud pop and then everything stops and the red light comes on flashing fast. This has happened in the past and has cost me close to $400 each time to fix. We love this machine, and I didn't want to get rid of it so I figured this go around I would try fixing it myself. I ask the repairer what screwdrivers they used to open the machine. After I gave him a $20 tip he referred me to your website. He also said that the primer unit was what had been replace each time. we have limited space and i like that the screwdriver comes in a small compartment. I can keep both the coffee maker and the screwdriver kit on my counter top for future repairs. I have had no difficulties fixing my Odea Giro while using the screwdriver set. Not only did it help me repair a $400 expense, but it also helped me take the black plastic sleeve off the frother and that has made a huge difference. been using my espresso machine like that for years, and that additive gave us bubbles. After fixing with these tools, i get great froth. And if we pack the espresso well we get an excellent crema. I set my expectations appropriately when buying with you and i am delighted with the service and product that you provide.
