Had we recently indulged the Kettles. Warm water is with us through induction Ruck Zuck. The signal of the flute is not audible. The flute has to be folded up to pour out the water. If you do that right after the "beep" is metal flap is not hot. The force required to open is very limited and is ok for us. Will be allowed to the boiler but the longer flap hot and you should have a potholder, etc. take care not to burn your fingers. The metal cover is also hot - but in Normalffall must be so taken in advance to replenish water and not directly after cooking. The opening is large enough to reach sometimes by hand and rag inside the boiler in order to clean this. Wesco admits 10-year warranty.
