All models, except the BB1 at 220-240V 50Hz, are equipped with an automatic pressure switch. When the slush led cold
drink led and led 1 blink on the electronic board at the same time, it indicates that the pressure switch intervened to
deactivate the compressor; In this condition the freezing will be OFF, to avoid damage to the refrigeration system. The
machine goes into protection mode.
A too high temperature can be caused by:
1. Dirty filter; remove and clean the filter;
2. The machine is located close to a heating source and its internal temperature increases;
3. The air circulation is obstructed.
After solving the problem, the pressure switch will reactivate the compressor automatically.
Remove the plastic filter located on the side panel and clean the radiator with compressed air. This process have to be
