If the whistle on your Marta MT-3027 whistling kettle isn't working as it should, a simple fix might be all it needs. According to the Marta MT-3027 user guide, water droplets inside the whistle mechanism can affect its sound. To resolve this, gently shake the kettle a few times. This action should dislodge any water that's interfering with the whistle, helping it to produce a clear, loud sound when the water boils.
