Why didn't Aiden's water tank drain completely during Instant Brew with the cone filter basket?

If you notice that your water tank isn't completely draining during an Instant Brew cycle with the cone (single-serve) filter basket, there's no need to worry! Aiden limits brews with the cone filter basket to 450ml (~15oz) to avoid overfilling the basket by accident during brewing. The last thing we want is for you to have muddy coffee water all over your countertop! As a result, initiating Instant Brew with the cone basket inserted will automatically cap the brew at 450ml and if you have more than that in the tank, you'll have some water left over.
