Query: I used it 15 times and stopped working

When I first got this machine it worked very nicely, you get very creamy ice cream in about 20-25 minutes. Just after the 1 year warranty expired the machine stopped freezing, meaning that the motor is working but the mixture is not getting cold, so something with the cooling system went bad. If you get this machine I will recommend you to use it as much as possible during the first year so if it breaks you are still cover for the warranty.
