Introduction: Ice machines are widely used in cafes, KTV, Internet cafes, hotels and other places. Generally, there will be no problems when using ice machines under normal maintenance, but if the maintenance is not in place or the use environment is not good, various problems will occur. The principle of ice maker is similar to that of refrigerator air conditioner, so we must pay attention to the heat dissipation problem when using it. The main manifestations of poor heat dissipation are: prolonged ice-making time and even inability to make ice. Due to poor heat dissipation, the compressor is overheated, which prevents ice making. Preliminary treatment: Open the cover to observe whether there is dust on the heat sink that affects the wind flow or other foreign objects that block the heat sink, and just remove it. In addition, if a fan is used to dissipate heat, see if the fan is operating normally.

another reason why the ice maker doesn't make ice is that it doesn't supply water. Because the water pump is broken, it is impossible to put the water pressure on the ice tray, but of course it is impossible to make ice. If possible, clean the water pump every two months, if the water filtration system is not good, clean it once a month, or replace the water filtration system. Otherwise, the scale will jam the water pump. Even burned. The whole water circulation system for ice making should be cleaned regularly, so as not to affect the ice making effect.

If it is found that the ice making time of the ice maker is longer than before, it is estimated that the refrigerant in the refrigeration system is insufficient after the above problems are eliminated. In this case, it is generally necessary to add refrigerant. If the leakage is serious, there is pressure test and leakage detection. After repair welding, add refrigerant. If the ice maker does not deice, it will involve problems such as computer boards and sensors. In this case, it is generally necessary to ask a professional master to go to the door to check the reasons why the ice maker does not deice and check

Notes:

1. The compressor works intermittently:

1. The voltage is too low. Check power supply.

2. The contact of the handover contact is not good.

3. System pressure protection.

4. The compressor starter fails.

5, the condenser is too dirty, high pressure protection.

second, the ice production is reduced.

1. The capillary tube or expansion valve is blocked.

2. The water in the system is too high and there is slight ice jam.

3. The condensing system of the ice maker is blocked.

4. Insufficient or leaking refrigerant.

5. The evaporator is too dirty.

third, the wet ice flakes are not hard.

1. The environment temperature is too high, especially in summer.

2. Add more refrigerant to the repaired machine.

3. The water supply of the water distributor of the ice machine is too large.

4. The power of the press is insufficient.

fourth, the machine runs but no ice is produced.

1. The water in the water tray is not enough or there is no water.

2. The reducer is faulty or the motor is decelerated.

3. Ice jam due to system failure. Dirty blockage, etc.

4. The ice machine leaks snow seeds, and the pressure is not enough.

5. The ice is not thick enough.

5. The ice machine leaks water.

1. The amount of water supplied by the water inlet valve is too large.

2. The connecting water pipe is damaged.

3. Failure of the pipe hoop.

4. The water level float valve is faulty.

6. excessive noise.

1. The fan of the ice maker is faulty.

2. The reducer is faulty.

3. The compressor is noisy.

seven, water shortage alarm.

1. The filter screen of the water supply connector is blocked.

2. The water supply pipe is blocked.

3. The water inlet valve is blocked.

4. The drain valve leaks.

5. The water pump is out of order.

VIII. System failure on startup

1. Phase sequence problem.

2. Power supply system failure

3. Control panel failure

Precautions for ice making:

1. The ice maker must be kept horizontal, otherwise it will not remove ice and generate noise during operation.

2. The gap between the back and the left and right sides of the ice maker is not less than 3cm, and the gap at the top is not less than 6cm.

3. The ice maker should use independent power supply, special line power supply, fuse and leakage protection switch, and be reliably grounded.

4. The water used for the ice maker should meet the national drinking water standard, and a water filtering device should be installed to filter impurities in the water, so as not to block the water pipe and pollute the water tank and ice mold. And affect that ice-making performance.

5. When cleaning the ice maker, turn off the power supply. It is forbidden to use water pipes to directly aim at the fuselage for washing, and use neutral detergent to scrub. It is forbidden to use corrosive solvents such as acid and alkali for cleaning.

6. The ice maker must unscrew the head of the water inlet hose for two months, and clean the filter screen of the water inlet valve, so as to prevent the water inlet from being blocked by sand and mud impurities in the water, which will cause the water inlet to become smaller and lead to no ice making.

7. The ice maker must clean the dust on the condenser surface every two months. Poor condensation and heat dissipation will cause damage to compressor parts. When cleaning, use a vacuum cleaner, a small brush, etc. to clean the oil and dust on the condensation surface, but not sharp metal tools to avoid damaging the condenser.

8. The water pipe, sink, refrigerator and protective film of the ice maker should be cleaned every two months.

9. When the ice maker is not in use, it should be cleaned, and the water in the ice mold and the box should be dried by a hair dryer. It should be placed in a dry and ventilated place without corrosive gas to avoid being stored in the open air.
