1、把水桶摘下来，买一些饮水机专用除垢剂，一次用一小袋，放入饮水机上面的水槽内。
1. Take off the bucket, buy some special scale remover for drinking water machine, use a small bag at a time, and put it into the sink above the drinking water machine.
2、再把冷热水嘴打开，用杯子把水接住，放入水槽内，反复几次，直至除垢剂完全流入饮水机内。
2. Open the hot and cold water nozzle, catch the water with a cup and put it into the sink several times, until the detergent completely flows into the drinking water machine.
3、然后关闭冷热水嘴，通电加热，水温达到80度左右时断电。
3, then turn off the hot and cold water nozzles, power up and heat up, and when the water temperature reaches 80 degrees or so, the electricity will be cut off.
3、过两个小时后，把饮水机底部的一个胶塞拔出，把加热的水放尽，再用清水清洗几遍。
3. After two hours, pull out a rubber plug at the bottom of the water dispenser, drain the heated water, and rinse it several times with clean water.
4、再把胶塞堵上，通电加热，再把水放尽，注意，开始几次热水不要喝。反复几次后就清洗干净了。
4, plug the rubber stopper again, electrify and heat up, then drain the water. Notice that you should not drink hot water for a few times. After several times, it was cleaned.
这样清洗的主法有一个缺点，就是水垢不能除干净。如果你动手能力较强的话，可以把后盖打开，把加热罐卸下来，拧下螺丝把里面的杂质清除出去，然后再装好，效果就很理想了。提醒注意的是，在卸下加热罐时，把线头做个记号，别装错了。
The main disadvantage of this cleaning method is that dirt can not be cleaned. If you have strong hands-on ability, you can open the back cover, unload the heating tank, screw down the screw to remove the impurities inside, and then pack well, the effect is ideal. It is important to note that when the heating tank is removed, mark the thread and do not install it wrongly.
