We have a really nice coffee maker, which we received as a gift. It has its own built-in grinder, so we get to start each morning with fresh-ground coffee. It's a Cuisinart model. It's rather intricately arranged -- it has a built-in reservoir for water, and the bean grinder is made of two parts that fit into the top, where you pour the water in.
They're connected to the basket where the water passes through the filter using a small downspout; the basket itself has a top cover that helps to guide the ground beans into the filter within. The basket is held in place behind a spring-loaded door that you have to give a solid push to in order to get it to lock in place. A bulb on the underside keeps the brewed coffee from going into the carafe underneath unless the carafe is in place -- presumably to stop the flow of coffee to the carafe, for impatient users who want to pour a cup before the pot is completely brewed (a mistake, in my opinion, as the coffee brewed at the start of the batch tastes different from the coffee that comes out at the end; one should mix the entire pot to get the optimal flavor).
A thermal carafe is underneath, equipped with a one-way lid to keep the coffee at an optimal temperature (because thermal plates burn coffee and foul the taste, there's no burner -- the hottest the coffee gets is when it's first brewed).
So in order to brew a cup of coffee, there are no less than seven individual parts you need to keep track of: the carafe, its lid, the two pieces of the basket and the filter and the top and bottom of the bean grinding mechanism.
When it works, our coffee machine brews a fine cup of coffee, but as you can see, it's like putting a jigsaw puzzle together. And inevitably I do this in the morning, when I'm not fully awake, rather than the night before.
This is partly by design: The first morning we tried to make coffee in it, I used the timer and set it up the night before. Something went horribly wrong, and it went everywhere. There were coffee grinds all over the counter and hot, brownish water spilling everywhere. Emmeline woke me up to tell me there was a huge mess in the kitchen.
This is also partly by schedule: Usually the coffee pot and the other assorted dishwasher-safe accessories are washed in the dishwasher along with the rest of the daily load, which usually isn't washed until the evening, after supper. As a result, the coffee machine isn't usually ready for setup until very late. More often than not, after I've already turned in for the night.
Well, every once in a while, I'll screw up the setup. This was one of those mornings.
I'm not sure what went wrong, but my guess is that somehow the plug that keeps the brewed coffee in the basket when the carafe is removed was blocked somehow, and there was a torrent of coffee and ground beans all over the counter this morning. Bob spotted it a few minutes after I'd started brewing it, but not fast enough to avoid the damage. It was about a half an hour's worth of cleanup and sanitization of the coffee maker before I could try again.
Must be Monday.
