What is the reason why the water dispenser does not produce hot water and cold water?

1. The low-pressure solenoid valve is broken or blocked.

2. If there is a lack of water after short circuiting, the circuit board will be burned.

Related Notes:

1) The handling machine should be handled gently, when moving the water dispenser refrigerated by the compressor, it should be kept upright as much as possible, if it is to be tilted, its tilt should not be greater than 45 degrees, and it should be stationary for a period of time after handling before it can work.

2) When using the water dispenser for the first time, clean the containers and pipelines of the water dispenser with clean water, then unscrew the drain valve, and tighten the drain valve after draining the remaining water in the machine. After adding a large bottle of water, turn on the hot water faucet, and then plug in the power supply and turn on the heating switch after the water flows out, so as to avoid dry boiling and prolong the life of the machine.

3) If the water dispenser is out of use for a long time, please turn off the switch of the machine and unplug the power plug, then unscrew the drain valve, drain the remaining water in the machine, and then tighten the drain valve (please pay attention to hot water scalding during drainage.)

4) It is best to disconnect the power supply when not in use at night, which can save energy and ensure safety when no one is using it.

There are two situations, one is that the hose is blocked by limescale, and the other is that there is air in the hose that cannot be discharged, resulting in a small water flow. The solution is: take the bucket down, open the hot water drain valve at the back, and drain the water.

After that, turn on the hot water faucet in the front and plug the drain valve in the back. Put the bucket with the hot water tap open and wait until the hot water tap comes out before turning off the faucet. In this way, the air can be pressed out of the tap by the water, and the water will flow smoothly.

As an indispensable consumer product in modern life, water dispensers have been widely used in many families and enterprises. Especially in the cold winter, drinking hot water is indispensable. However, some users may find that cold water can come out, but hot water can't come out when using the water dispenser.

The following is an introduction to the reasons why the cold water from the water dispenser cannot produce hot water.

1.Faulty heating tubes.

The heating pipe of the water dispenser is an important part of heating the water to the desired temperature. If it is found that the hot water is not produced properly, it is possible that the limb disassembly of the heating pipe is faulty. Heating pipes usually need to be cleaned regularly to keep them in normal condition, and if they are not cleaned for a long time, they can cause problems with the heating pipes.

2.The power cord is faulty.

The power cord of the water dispenser is also a common problem, and if the power cord fails, it will not be able to generate enough power to start the water dispenser and thus heat the water. To check the power cord, you need to first check that the power cord is connected to a power outlet, and if it is connected and still not working, you may need to replace the power cord.

3.Controller failure.

The controller of the water dispenser has an important role, it is used to control heating, refrigeration and other functions. If the water dispenser cannot be heated, it may be caused by a malfunction of the controller. To solve this problem, the controller needs to be replaced.

4.The temperature sensor is faulty.

The temperature sensor is one of the important components in the water dispenser, which is responsible for monitoring the temperature of the water and ensuring the working state of the rock heating pipe and the refrigeration pipe. If the temperature sensor fails, the drinking calendar closure machine may not be able to detect the correct water temperature, resulting in the inability to heat the water.

In general, there may be many reasons why the water dispenser cannot produce hot water from cold water, and a comprehensive repair and maintenance of the water dispenser is required. At the same time, every user should also pay attention to regular maintenance and cleaning when using the water dispenser for a long time to ensure the normal use and life cycle of the water dispenser.

Water dispenser is one of the indispensable devices in modern life, and the usage rate of its hot water function is also quite high. But sometimes we find that the hot water function of the water dispenser suddenly does not come out and cannot be used. At this time, we need to deal with it accordingly, and here are some solutions.

1.Check whether the power plug is plugged in tightly: sometimes we will accidentally kick the power plug when cleaning the water dispenser, resulting in the plug being loose, if the power plug is not tight enough, it will affect the normal use of the hot water function, at this time you need to check whether the power plug is plugged in tightly.

2.Check whether the hot water switch is turned on: The hot water function of the water dispenser needs to be controlled by the switch, if the hot water switch is turned off unexpectedly, it will cause the hot water not to come out, so you need to check whether the hot water switch is on.

3.Check the heating pipe for damage: The heating pipe of the water dispenser is also the core component of the hot water function. If the heating tube is damaged, it will affect the heating and outlet of the hot water, and it will be necessary to replace the heating tube with a new one.

4.Cleaning the filter: The filter of the water dispenser is an important guarantee to prevent contaminants from entering the tank and internal circulation. If the filter is not cleaned for a long time, it will cause blockage and affect the smooth flow of water, so the filter can be removed for cleaning.

5.Adjust the thermostat: Different water dispensers have different thermostat adjustment methods, if we encounter the situation that the water dispenser does not have hot water, we can also try to adjust the temperature of the thermostat or see if there is a fault.

In short, when we encounter the situation that the water dispenser does not have hot water, we should first eliminate simple problems and gradually investigate. If the above methods still do not solve the problem, it is recommended to contact professional maintenance personnel for maintenance.
