Repair and Maintenance of Commercial Bingsu Machine
Commercial bingsu machine help your restaurant make delicious desserts, but even after a pre-opening inspection, there is a risk of malfunction in use. Equipment failure can greatly affect the restaurant business, this repair guide can help you check and fix some of the problems yourself when the bingsu machine breaks down, reducing business losses.

1. How to repair the common problems of bingsu machine?
Some problems involving bingsu machines can simply be fixed, unless the components are damaged and need to be replaced or repaired, in which case you will need to promptly notify the merchant for after-sales service. You can refer to this repair guide to determine the cause of the problem and reduce the cost of communication with the merchant and professional repair workers.
A. Stopped or no response
The machine stops shortly after turning on and does not respond
The equipment can be turned on and run means the power connection and circuit load is normal, stopping because the automatic protection is triggered, you need to check whether the machine cooling system is operating properly.
Processing method: For an air-cooled type commercial bingsu machine, the probability is that the cooling fan is damaged and can not run, need to check and replace. For the water-cooled type, the inability to dissipate heat is because of the water inlet connection problem or did not open the water inlet switch.
The machine does not respond in any case
If the machine can not be turned on at the beginning then you need to check the power connection and circuit load to determine whether it is a wiring problem or the circuit components of the machine itself are damaged.
Processing method: Check whether the socket is loose, and whether the leakage switch is protected, if normal then you need to thoroughly check the equipment’s electrical components and replace them.
B. Cooling problems
Not cooling
• Compressor does not run
Compressor operation will produce a slight noise if the machine is completely quiet means the compressor is not running, this indicates that the compressor control components are damaged (e.g. capacitor, starter).
Processing method: Check and replace the damaged components.
• The compressor is running but not cooling
The compressor can run normally to exclude component failure, not cooling means refrigerant leakage or exhaustion.
Processing method: Check the cause and part of the leakage, re-vacuum and refill the refrigerant.
Poor refrigeration effect
• Only the middle part of the refrigeration roller is iced
The normal operation of the commercial bingsu machine will be evenly iced throughout the roller, and only part of the place can be cooled is also the problem of refrigerant leakage.
Processing method: Check the cause and part of the leak, re-vacuum, and refill the refrigerant.
• Refrigeration roller ice is not solid
The ice is not solid, indicating that the refrigeration system’s heat dissipation is poor, making the refrigeration temperature rise.
Processing method: For air-cooled type equipment, first check the cooling fan, if damaged then replace it, the second step is to check whether the air vent is blocked and clean the air vent. For water-cooled type equipment, first, check whether there is a problem with the water inlet connection and whether the water inlet switch is open, the second step is to check the drainage port blockage if the blockage is cleaned.
C. Poor ice-making effect
The roller ice unevenly
The refrigeration system can operate normally but the ice on the roller is uneven, this situation should consider the problem of raw materials, raw materials themselves are not suitable for ice making, or uneven mixing will lead to uneven icing.
Processing method: Re-mix or replacing the raw materials.
Poor ice granularity
There are two main reasons for this situation: the blade is not sharp enough; the roller and blade gap is not suitable.
Processing method: Re-polish or replace the ice scraping blade; adjust the distance between the blade and the roller, preferably keeping it at 0.6mm, which is the best distance to keep the ice flake form.
D. Roller does not rotate
There is a motor sound but the roller does not rotate
The motor can operate normally, but the transmission chain failure can not drive the roller, mostly because the transmission chain is off, disconnected, or slipping.
Processing method: Tighten the drive wheel screw, and replace the chain or sprocket.
The roller does not rotate and there is no motor sound
The motor can not operate normally, judged as motor components damage or controller damage.
Processing method: Professional maintenance personnel are needed to replace the motor or controller. You can inform the maintenance personnel of these conditions in advance so that he can prepare the replacement components more quickly.
E. Leakage of raw material from the raw material tray
The operation process of the commercial bingsu machine is that the raw material flows from the barrel/bottle to the raw material tray, and the roller rotates to continuously dip the solution from the tray for cooling. The tray will produce leakage because, in addition to its breakage, it is more likely that the connection with the raw material barrel has air leakage or is not fully connected.
Processing method: Check if the connection is damaged, tighten the connection if it is not damaged, and if it is damaged it needs to be repaired or replaced.
F. Rotating discs do not rotate
Some bingsu machines will be equipped with ice-catching discs that can rotate, so you don’t have to catch the falling ice flakes manually, and by rotating them, you can make the snowflakes pile up into a beautiful hill shape. The rotating disk does not rotate means that the rotating motor is malfunctioning.
Processing method: Repair or replace the rotating motor.
2. How to clean the bingsu machine?
Proper cleaning and maintenance can not only extend the life of commercial bingsu machine but also reduce the risk of failure. To ensure safe and hygienic use, it is recommended to deep clean the machine at the end of each business day.
A. Cleaning steps
• To ensure safety please unplug the machine before cleaning.
• Disassemble the drum, feed tube, ingredient tray, and dispensing chute for cleaning.
• Rinse the rollers and blades, taking care to use a low water flow to prevent water from splashing or entering the machine. For bingsu machines with automatic cleaning functions, they will spray water to clean the rollers and blades by themselves.
• Dry the surface of the equipment to prevent rusting in humid environments by keeping the surface dry.
• Cover with a shield or use other items to cover the rollers and blades to prevent dust from falling.
B. Maintenance Tips
• Do not immerse the machine in water or rinse the casing directly. Clean the casing by wiping it with a damp rag.
• Avoid using hard brushes to clean the surface of the machine.
• To ensure the cooling effect, the bingsu machine should be kept away from heat sources and leave enough space for heat dissipation (especially for air-cooled types), usually a distance of 30cm should be left.
• Check the water connections or clean the exhaust system every month, this helps the machine to dissipate heat and cool better.
3. Summary
Proper cleaning and maintenance of the bingsu machine will ensure that the taste and hygiene standards of the bingsu are at an optimal level. When it comes to professional operation, please contact a technician for inspection and maintenance, but of course, choosing a trusted supplier and quality equipment can greatly reduce the risk of failure.
