In this article, we will discuss how to resolve the issue of short circuit caused by fan malfunction in the Yamada NWD-700 water dispenser. By following the steps outlined below, you will be able to repair the water dispenser and restore its normal functionality.

1. First, ensure that the water dispenser is unplugged from the power source. Safety first!

2. Locate the position of the fan. Typically, the fan is located at the bottom of the water dispenser. You may need to open the casing of the dispenser to access it.

3. Thoroughly inspect the fan for any visible physical damage or debris blockage. Sometimes, dust, paper scraps, or other debris can impede the fan’s operation or cause a short circuit. If any debris is found, clean it thoroughly.


1. 首先,确保饮水机已经断开电源。安全第一!

2. 定位风机的位置。通常,风机位于饮水机的底部。您可能需要打开饮水机的外壳才能访问到它。

3. 仔细检查风机是否存在明显的物理损坏或杂物堵塞。有时,灰尘、纸屑或其他杂物可能会导致风机运转不畅或短路。如果发现有杂物,将其清理干净。IMG 5427IMG 5426IMG 5425

4. Check the fan’s power cord for secure connections. Ensure that the plug is tightly inserted into the socket and that there are no loose or disconnected parts.

5. Use a multimeter or voltage tester to test the circuit connections of the fan. Place one probe on the positive terminal of the fan and the other probe on the negative terminal, then measure if the current is normal. If no current is passing through, it is likely that the fan itself is faulty and causing the short circuit. You may need to replace the fan component.

After repairing the water dispenser, remember to conduct a comprehensive functionality test to ensure that all components are working properly. Additionally, perform regular cleaning and maintenance on the water dispenser to prevent similar malfunctions from occurring again.

By following the steps outlined above, you should be able to successfully resolve the issue of short circuit caused by fan malfunction in the Yamada NWD-700 water dispenser. If you require further assistance or have any other questions, please feel free to reach out to us.

4. 检查风机的电源线是否连接牢固。确保插头与插座紧密连接,并且没有松动或脱落的情况。

5. 使用万用表或电压表测试风机的电路连接。将一个探针放在风机的正极上,将另一个探针放在负极上,然后测量电流是否正常。如果没有电流通过,那么很可能是风机自身故障导致短路。您可能需要更换风机部件。
