Cleaning the Water Distribution Pipe and Water Distributor
During machine operation, regularly clean the water distribution pipe. Issues like scale and foreign
objects can easily block the small holes on the water distribution pipe, especially in the following
cases:
A.During ice-making, the compressor and water pump operate normally, but there is little or no water
flow from the water distribution pipe. The small holes on the water distribution pipe are blocked,
leading to abnormal ice shapes or insufficient ice.
B.During ice release, the compressor and water pump operate normally, but the ice often does not
fall off.
Note: Disconnect the power supply and drain the water from the bottom of the machine and
the water tank before cleaning.
1. Use a tool to remove the two screws on the upper rear part of the machine, as shown in Figure 1.
2. Press the "handle" position of the upper cover with your hand and push the "upper
cover"backward. After pushing it out, place the "upper cover" aside, as shown in Figure 1.
3. After removing the "upper cover", pull out the "three silicone tubes" from the "water distribution
pipe", as shown in Figure 2.
4. Press the "clip" on the side of the "water distribution pipe" backward, then pull the "water
distribution pipe" upward, and then take out the "water distribution pipe" obliquely upward.

matter in the water distribution hopper, as shown in Figure 4.
Usage Notes:
A. Always push the water tank completely into the machine after adding water.
B. Regularly check if the water tank, inner liner filter, and water distribution pipe are blocked by dirt
or impurities, affecting water flow. Clean them as needed.
C. The temperature of the added water and the environment directly affects ice production. Lower
temperatures yield more ice.
D. The quality of the water used affects the service life of the machine's recirculating pump. For
optimal results, use purified or distilled water. Abnormal noises during pump operation are typically
caused by water impurities and do not affect machine usage.
E. During operation, there is a 3-minute delay before the compressor restarts.
