Porridge escapes from the milk cooker

I bought a milk cooker Great Rivers. And the first experience was unsuccessful! I poured water strictly according to the instructions, measuring 200 ml with a measuring cup. It boiled pretty quickly, in three minutes. It whistled, I dodged it, but it didn't happen! Although I dodged the fire to the very minimum, the milk cooker continued to cheerfully spit water and yell. She put on an oven mitt, took off the whistle. And then the milk cooker, one might say, turned inside out. I had to urgently turn off the fire and save the stove. I cooked porridge in the cartoon. What am I doing wrong?

Well, or you have the very minimum - not so small. Maybe put the flame divider or rearrange it on another burner, where is the minimum? Or just use less water. Not 200, but 150, for example. Nothing wrong. In my here, according to the instructions, only 100 ml should be poured.
All the same, I think the fire is too big. I have a very low flame at minimum and the whistle is generally silent there. And when they bought the stove, the minimum was pretty big, and when (for another reason) we called the gasman, we asked along the way to adjust the height of the flame. Now everything is OK.

Next time I'll try to pour half of the norm and put it on the smallest burner for coffee. Can you cook right away with the lid closed?

Can you cook right away with the lid closed?

I put it on the middle burner, close the milk jug with a lid, as soon as the whistle goes off, move the milk jug to the smallest burner and turn the heat down to a minimum, the whistle is almost inaudible, it snores a little.

Thank you, I'll try this It's our third day of heat - too lazy to light the stove.
