Fortunately, the problem still easily. However, I would advise everyone prior to engagement in the interior of the kettle strongly against. I did it anyway and had to work less than five minutes rest before beeping. I have been to pull the plug subtracted the six plastic nipple on the bottom of the unit and solved the underlying dreischlitzigen special screws with a simple small flathead screwdriver. With the special screws the manufacturer probably wanted to install a hard to overcome hurdles, but very mature was not this venture. Directly below the "speaker holes" at the bottom I have to prying the aluminum top found the annoying signal transmitter. With a soldering iron I just resolved and withdrawn one of the two lead wires for signal generators of the board. For safety's sake I have now exposed wire wound inside, so it can not touch any other contact. But as I said, I recommend explicitly not to follow suit.
When I was at tinkering, I immediately measured idle power. This is 0.75 W. Assuming an electricity price of 25 cents per kWh the electricity costs of 1.64 EUR per year means idle. The already proposed here switchable adapter plug could be worthwhile. If you keep a good boy off to, you can handle even the tenfold beeping. One then has to endure only five times beep when it reaches the desired temperature.
Otherwise, the unit very functional and the design is appealing. That the current temperature of the water contained still appears after heating, I find excellent. However, the accuracy of the ad I could not check. Somewhat stiff strikes me as the flap for pouring in the water. I would imagine that this ensures a low life of the appliance.
