I, and family members, have been woken up in the middle of the night by this machine multiple times. It’s always in the defrosting mode when it’s loud. It sounds like the motor is being burned out. It’s unfortunate because I LOVE the nugget ice it makes. It doesn’t seem like it’s a very smart machine. I feel like it should automatically shut off when need be. I have not used the app on my phone, so maybe there’s something there I’m not seeing. The frequency the machine suggests to be sanitized or descaled is ridiculous. One a week, is super annoying. It starts to make ice within 20 mins, which is impressive. The ice is soft and is a great alternative to snack on rather than chips (why I bought it). I want to return the machine tho, too noisy!!!!
