Water dispenserReason for not cooling
Turn on the cooling switch and the cooling indicator light is on for the following two reasons:
The electronic cooling sheet is broken. The electronic cooling sheet is the core component of cooling. If it is damaged, the water dispenser will not be able to cool. The temperature of the water at room temperature is the same as that of the room temperature. In this case, the refrigeration switch should be turned off in time. The abnormal operation of the fan will easily lead to damage to the refrigeration piece!
The compressor cooling water dispenser is not cooling, and the indicator light is not on. There are two reasons for this fault:
The cooling thermostat is broken, and the whole machine is not powered on, so the water dispenser does not work. Refrigeration; a bad power switch will also cause the water dispenser to not be powered on.
The water dispenser is refrigerating but the cooling effect is not good, the compressor is cooling, and the cooling thermostat is aging:
It causes its performance to decline and the temperature control action is slow, when it should start working The compressor does not start to work; the compressor leaks fluorine, which causes the compressor work efficiency to drop, and the cooling is slow; the speed of the electronic cooling water dispenser decreases when the fan is aged, the heat dissipation capacity decreases, and the cooling time is greatly prolonged.
What to do if the water dispenser is not cooling
Failure reason: the electronic cooling water dispenser is not cooling
Solution: ①Turn on the refrigeration switch and the refrigeration indicator light does not light up due to the following two reasons: the circuit board is damaged, the circuit board is damaged and the refrigeration circuit power supply is abnormal, so the indicator light will not light; the fuse is burned out, and the fuse is burned out. Not much. Generally, the fuse is burned out due to other reasons. For example, when there is a short circuit in the circuit board, the fuse will usually burn out. After checking out the real reason and eliminating it, the insurance can be replaced and the power-on test machine can be replaced. ②Turn on the cooling switch and the cooling indicator light is on due to the following two reasons: the electronic cooling chip is broken, the electronic cooling chip is the core component of cooling, if it is damaged, the water dispenser will not be able to cool; the fan is broken, and the temperature of the heat sink cannot be dissipated in time after the fan is broken. Therefore, the water from the cold water faucet is hot or the temperature of the water is higher than the room temperature. In this case, the refrigeration switch should be turned off in time. If the fan does not work properly, it will easily cause damage to the refrigeration piece!
Cause of failure: compressor cooling water dispenser is not cooling
Solution: indicator light is off, two reasons cause this failure: cooling thermostat If it is damaged, the whole machine will not be energized, so the water dispenser will not be cooled; if the power switch is broken, the whole water machine will not be energized.
Cause of failure: The water dispenser is refrigerating but the cooling effect is not good
Solution: ①The compressor is refrigerating, and the cooling thermostat is aging: its performance is degraded, the temperature control action is slow, The compressor does not start work when it should be started; the compressor leaks fluorine, which reduces the working efficiency of the compressor and causes the cooling to be slow; ② When the fan of the electronic cooling water dispenser is aged, the speed drops, the heat dissipation capacity decreases, and the cooling time is greatly prolonged.
What should I do if the water dispenser does not heat?
First determine the type of water dispenser, because different types of water dispensers have slightly different heating capabilities. After a brief understanding of the heating methods of different types of water dispensers, you can check according to the principle to see what causes the water dispenser not to heat.
1. Thermal water dispenser
When the warm water dispenser is in use, press the heating switch, and the power supply will provide power for the “Keep Warm” indicator light. for power-on instructions. At the same time, the power supply is divided into two circuits: one circuit constitutes a heating circuit, which makes the electric heating tube energized to heat up; the other circuit provides voltage for the “heating” indicator light for heating indication. When the water in the hot tank is heated to the set temperature, the contact of the thermostat is disconnected, the power supply of the heating and heating indication circuit is cut off, the “heating” indicator light goes out, and the electric heating tube stops heating.
When the water temperature drops to the set temperature, the thermostat contacts connect to the power circuit, and the electric heating tube reheats, so that the water temperature is kept between 85-95 ℃ over and over again.
2. Semiconductor direct cooling hot and cold water dispenser
When the semiconductor direct cooling hot and cold water dispenser is in use, the direct cooling hot and cold water dispenser The water tank provides room temperature water and enters the water in two ways: one way enters the cold gallbladder container, and the cold water is refrigerated; the other way enters the hot tank, and the hot water is heated.
Press the heating switch, the heating indicator light is on, the electric heating tube heats up, and the water in the hot tank heats up. When the water temperature reaches the set temperature, the contact of the thermostat is disconnected, the heating power is automatically cut off, the heating indicator light goes out, and the electric heating tube stops heating. When the water temperature drops to the set temperature, the contact of the thermostat is closed, the heating power is automatically connected, the heating indicator light is on, and the electric heating tube heats up. Then repeat the above process to keep the water temperature constant between 85-95°C.
3. Compressed refrigerated water dispenser
Press the heating switch, the heating circuit is connected, the red heating indicator lights up, and the electric heating tube heats up. When the water temperature rises to the set temperature, the thermostat will be reset automatically, the power will be cut off, the red heating indicator will go out, and it will enter the heat preservation condition. After the power is cut off, the water temperature gradually drops. When it drops to the set temperature, the contact of the thermostat is closed, the power is turned on, the red heating indicator light is on, and the electric heating tube heats up again. In this cycle, the water temperature is controlled between 85-95 °C.
It is common that the heating belt inside the heating tank is damaged, and the heating tank needs to be replaced. There are many problems with the temperature controller. You can try shorting the temperature controller, and replace a temperature controller if it can be heated. If the heating tank cannot be heated, the heating tank should be replaced. You can also use a multimeter to measure the resistance of the heating tank and the temperature controller. If the needle does not deflect, it means that the heating tank heating belt is open circuit or the temperature controller is in poor contact.
Water dispenser leaking repair method>>
Internal: including internal silicone tube aging and rupture, cold/hot tank weld aging, Internal overflow caused by leakage of ice gallbladder, leakage of pipeline machine (solenoid valve), water bottle and other components.
Resolution: Replace the part.
Top: If the top leaks, it is usually caused by a broken part of the water bottle. The other is that there is a problem with the floating ball of the clean water bucket and it cannot be sealed, but this usually does not happen.
Solution: Use is to check whether the water bottle is broken.
Faucet: Most of the reasons are that the head end cover is loose, the internal silicone sleeve is broken, or there are impurities and scaling inside.
Solution: Tighten the head cover and clean the impurities. If none of the above work, then only the faucet can be replaced.
