Once the water is heated the brewing time on the Keurig K55 coffee makers depends on the size of the mug you choose. All mug sizes will be brewed in less than one minute. As long as the machine remains on it will only take 15 seconds to heat the water for additional cups.

Cup Sizes and K Cups

There are 3 cup sizes on the Keurig K55 coffee makers. You can choose from 6 oz, 8 oz, or 10 oz. If you like a stronger brew then you will want to use a smaller cup size. A lighter flavor then a larger cup size. You can use a travel mug up to approx 7 inches tall by removing the drip tray.

The K55 will accept all k cups from all manufacturers not just Keurig. This will give you a lot of flavor choices. You can also purchase a k cup universal reusable coffee filter and fill it with your favorite coffee, cappuccino, hot cocoa, and tea flavors and save money on disposable k cups.

This is a nice feature that will automatically shut off your K55 coffee maker in 2 hours. It keeps the water heated and ready to go so you do not have to wait for the water to heat again after brewing your first cup of coffee.

This is NOT a timer. You can not set it to make you a cup of coffee at a set time. You will have to manually do this. It is only to shut the machine off.

When you press the power button the power indicator light will turn on. While it is heating your water the heating indicator light will illuminate. Once you insert your k cup the three mug size buttons will light up for you to make your mug size choice. This button will remain lit up until it is finished brewing you cup of coffee.

Cleaning Keurig K55 Coffee Makers

The K55 is equipped with needles that puncture the k cups for brewing. These needles need to be cleaned by simply running straight hot water through it after you brew sweet beverages such as hot chocolate and cappuccino.

You will occasionally need to remove the k cup holder and rinse out the pieces and then put them back into the machine.

Cleaning the outside of the Keurig K55 coffee is pretty simple. All you really need to do is wipe down the outside and take the water reservoir off and clean it out with water and wipe it down.

Regular Maintenance

Regular maintenance for a Keurig single cup coffee maker includes the water filter and descaling. Both are purchased separately.

The water filter filters out impurities that may harm your keurig machine. If you already use bottled or filtered water you do not really have to have one, that is totally up to you.

Descaling is similar to cleaning out a regular coffee maker. It is a liquid solution that you run through your Keurig machine that cleans and descales it. You should do this every 3 to 6 months or when the descale indicator light comes on.

A Keurig associate has stated that you can use plain white vinegar in place of the descaling solution.
