" 6: Mix the water and coffee with the stirrer for about 10 seconds

7: Wet the rubber seal and insert the plunger into the chamber (note no time delay specified in the official directions)..... 8: You've just made a double espresso. For American coffee, top-off the mug with hot water ( I probably added a tad too much hot water ). For a latte, top-off the mug with hot milk"

My grind might have not been fine enough ? Also, I didn't boil the water but used my old coffee maker. Would it not be hot enough using the old coffee maker ?
