During operation, when ice accumulates in the
ice bin to a certain height and reaches the set
level for a full bin, and such state has been
detected and lasted for a period (60 seconds),
the machine will believe the ice bin is full and
automatically stop working.
Resuming ice making when ice bin is full:
When ice is taken from the bin and the
accumulation height decreases as a result, the
machine will detect that the level is below the
set value after 2 minutes, and re-enter the
normal ice-making mode.
