My household recently acquired a Kitchencook TEATIME kettle. It's quite fancy, with a handful of features that I don't really use nor care about, but I'm quite content with its 1.7L capacity.
Unfortunately, it beeps a lot. Here is a non-exhaustive list of things resulting in a dreadful unwanted noise: removing/putting the kettle from/on the base, when the water is at the right temperature, when one turns it off/on, when one presses a button, … sometimes even in the middle of the night for no apparent reason. This is fucking unacceptable behaviour, so here is how to fix it. Start by doing yourself a service and get yourself a screwdrivers kit from iFixit, as Kitchencook apparently hates their customers and decided to use Tri-angle screws for the base:
Once open, remove the 3 phillips screws fixing the PCB to the base:
The buzzer is the small cylindrical device on the bottom-left of the PCB:
It's a small piezo from ZFLY (Zhongshan Zhongli Electronics). The way piezoelectric speaker are working is by having a small piece of piezoelectric material fixed to a metallic diaphragm, and to excite it via a small alternative voltage, so that the disc will shrink/expand, causing the diaphragm to vibrate, and thus create sound. Silencing the infernal machine is simply a matter of removing the diaphragm altogether:
I'd recommend taping it to the plastic somewhere on the inside of the base, so that you can always put if back should you part with the device, and hand it over to some unhinged noise-lover maniac.
You should now be able to enjoy your tea in a blissful silence.
