Q. Why isn’t my kettle whistling?
A. If your kettle no longer whistles, please follow these simple steps:
Firstly, empty the kettle of water and tip it forwards as if pouring. You should hear the ball in the spout tip forward and then go back when you put the kettle in its normal standing position. This is the first process of elimination.
Secondly, fill the kettle with water to the seam line and not above. Once filled and the kettle has been returned to a horizontal position, give the kettle a gentle shake to ensure the ball bearing in the spout has returned to its resting position.
Finally, check to ensure that the lid is pushed down tightly and that the whistling hole is facing towards the spout. Very often this is just an oversight by not actually closing the lid properly. The whistle occurs when the lid is pressed securely, the ball is in the resting position and the steam can then escape primarily through the reed in the lid.
One or a combination of the above – will affect the performance of the whistle.
