Most people who prefer to start their day with a cup of their favorite coffee,
coffee maker is a must. You just need to scoop up the coffee, add water, and
turn on the coffee maker. Your coffee is ready in an instant.

Would you like to see how does a (drip) coffee-maker look like?

Most of the modern day drip coffee makers are surprisingly simple device. These
coffee makers are pretty straightforward once you open them up. They have a
warming plate inside. Inside the coffee maker, you will find three
things:

A little bucket which holds the water you pour to make coffee. There is a
hole in the bottom of the bucket.

A coffee maker will also contain a black tube which will carry the hot water to
the drip area.

Water arrives in the drip area from the black tube and simple falls through the
holes on the coffee grounds.

Generally, the coffee maker will have a orange color tube in the center
which is nothing but the hot water tube (which connects the black tube). There
is another tube which picks up cold water from the hole in the bucket. It also
has a power cord coming in as well as the switch which turns the coffee maker on
and off.

How does a coffee maker works?

Making coffee in a coffee maker is very simple. You just need to follow the
following steps.

You pour some cold water inside the coffee maker, in the bucket. From the
bucket, this water flows through the hole in the bottom and into the orange
tube.

This water will then flow through the one-way valve into the aluminum tube in
the heating element, and then partially up through the black tube. All these
actions take place due to gravity and not any hi-fi mechanism.

After pouring water, you turn on the switch, and after this the heating element
will start heating the aluminum tube, and thus the water in the tube will begin
boiling.

As the water boils, the bubbles will rise in the black tube. Now, since the tube
is small enough and the bubbles are big enough that a column of water can ride
upward on top of the bubble.

The hot water flows out from the end of the black tube to drip into the
coffee.

Since there is no moving part, this makes the drip coffee maker very reliable.
Some basic things which can go wrong in coffee maker are:

The power cord or on/off switch can go bad: In either of these cases, it's best
to get a pro to replace it or buy a new coffee maker -- replacing it
improperly can lead to a fire.

The one-way valve can get clogged open or closed: You can usually fish out the
debris that causes this problem with a toothpick.

The tubes can get clogged with calcium: This is especially true of the aluminum
heating tube. The normal way to solve this problem is to run vinegar through the
machine once, and then run two batches of water through to clean out the
vinegar.

Some features to look for before you buy a coffee maker:

Wait, and then serve: This is a common feature which even the least expensive
coffee maker will have. You can remove the coffee pot before the brewing
cycle is complete, without having coffee dribble all over the heating plate. The
opening under the filter is low and touches the top of the pot. The valve closes
when you take out the coffee pot.

Water Filter: Most of the expensive coffee makers have water filters. The
function of these water filters is to take out any chlorine or iron taste from
the tap water which we may add.

You may also ask for a permanent coffee filter and integrated bean grinder in
your coffee maker.
