1.Automatic cleaning
Automatic cleaning after power on (Once,2 minutes)
Each time when the ice machine is switched on, it performs a 2-minute automatic
cleaning procedure, to rinse the floaters out of the ice trays and tank. In 2 minutes,
the water tank is continuously filled and the pump is running. Operator can hear the
sound of pumps working, and water flows down to the tank from the top of the ice grid.
Then the water spills out of the tank and flow away from the outlet of ice bin.
2.Ice making(Cycle,up to 40 minutes)
After automatic cleaning, the pump will start up in 45 seconds, then the ice making
begins. While making ice, the pump continues to work. Water flows from the top of the
ice grid down into the tank, and the water slowly cools until it freezes. In the process of
ice making, the thickness of the ice is measured by an ice thickness detector, When the
setting ice thickness is reached, the program moves to the ice-shedding step. If the gap
of ice thickness detector is too large, once the ice making time exceeds 40 minutes, it
will also be forced into the ice-shedding process
3.Ice-shedding(Cyele,up to 40 minutes)
During the Ice-shedding process,the ice grid is heated and the surface of ice at
where sticking to ice grid become melting, because of the gravity of ice itself, it will
fall off and complete a shedding process.
The falling ice blocks will push the baffle to turn over, and the baffle will be reset due
to itself-weight, then the machine started making ice again. However, when there are
too many ice blocks in the ice bin, the ice blocks against the baffle and so that the baffle
cannot be reset, the control chip indicates that the ice is full and the ice machine will
stop temporarily until the baffle is reset.
1.Water pump Directly observe whether there is water flowing from the ice
grid. If there is no water, the pump will be failure.
The steps of an ice machine are divided into there parts:
Fault self-diagnosis
2.Refrigeration After 10 minutes of ice making, the water in the sink becomes
noticeably colder, that you can easily feel the low temperature.
3.Water feeding In the process of automatic cleaning, water can be observed
to flow continuously from the overflow pipe of the water tank into the ice bin. However,
water will normally account for more than half of the water tank.
