My coffee maker brewed one morning and then shut off as normal and I went to work. The next morning I got up and only the power came on, but it wouldn't get hot, brew, or nothing! The coffee maker is over 90 days old, so I couldn't take it back to the store I bought it at. I was very frustrated until I found a few youtubes instructing me to use tools like these to repair it. They were right, with the right tools - the repair was easy. Turns out I had a clogged line. Used the screwdriver set to remove the security fastener to pull off the case. Got into the guts of the maker and fixed it before work the next morning.
