不响的原因：新买的水壶，一边在烧开水后是发声的但时间长了，壶盖有些松动，里面的响哨部件错位，与出厂时挑好的位置有了变化，一般就会出现不响或者是声音不大的情况
如何维修呢？分为以下几个步骤：
一、拆开壶盖内外构件，不熟悉结构的朋友一定要记住原来各个部件的先后位置，如画下来水壶的响哨构造也可以。

二、然后打开构件，清洁一下弹簧片周围的污物，一般是有水垢堵住出气孔了！

三、清洁完毕后，调整哨的三个弹簧片位置，让有铆钉的一面朝向壶内，然后三个弹簧片水平方向与壶盖外面的小盖的三个排气孔保持平行，使气流保持通。

四、最后拧紧螺丝，此时不要因为拧螺丝而使原来调整好的构件错位。这样一般就会正常发声了，如果还是不响，就应照上述方法和位置微调其相对位置。
