The Ionmax Rhine Pro ION651 has automatic defrosting, it means the unit removes frost or ice buildup by itself, so you don't need to manually switch it off and scrape away ice. 


During the defrost cycle, the appliance briefly stops cooling and uses a built-in system to melt accumulated frost. 

The water is then drained or evaporated automatically. 


Please refer to the user manual for details on the automatic defrosting feature, as this may explain the behavior you are experiencing.
