The Krups Mini Espresso 963A is a compact, steam espresso machine. Unlike an automatic drip coffee maker, an espresso machine uses steam pressure to push very hot water through coffee grinds to create a full-bodied, rich espresso. Since the espresso is so strong, it is typically served in small cups known as demitasse cups. The Krups Mini Espresso machine makes up to four demitasse cups and features a cup adapter that lets you brew espresso directly into two demitasse cups.
Plug the espresso machine into an electrical outlet. Make sure the On/Off switch is in the "Off" position.
Insert the filter basket into the filter holder. Fill the basket with espresso coffee grinds to the "2-cup" or "4-cup" marks. Lightly pack the coffee without overfilling the basket. Wipe off any excess from the filter rim.
Align the arrow on the thumb guard of the filter holder with the arrow on the left side of the espresso machine. Insert the filter holder into the brewing head, then lift the holder up and turn it firmly to the right as far as it will go until the arrow is as far right into the "Lock" range as possible.
Turn the boiler cap, located on top of the machine, counterclockwise to unscrew it. Use the glass carafe to measure 2- to 4-cups cold water. Pour the water into the boiler compartment, adding a little extra water to account for what is lost to steam. Do not fill the water beyond the metal band.
Replace the boiler cap and tighten it. Place the carafe lid on the carafe, making sure the lid opening points toward the pouring spout of the carafe.
Place the overflow grid onto the base of the espresso machine to catch spills, and place the carafe under the filter holding. Make sure that the nozzle in the filter holder points through the opening in the carafe.
Turn the steam release knob clockwise to securely close it. Press the On/Off switch to the "On" position, the indicator light will light up. Allow two minutes for the water to heat up. The water will start to pass through the espresso grinds and slowly drip into the carafe or cups.
Turn the espresso machine "Off" when the coffee has finished brewing. Unplug the machine and allow it to completely cool down before cleaning. Carefully open the steam release knob by slowly turning it counterclockwise.
Close the knob if you notice any steam coming from the nozzle, which means that the water is still under pressure. Fill a pitcher with cold water and hold it underneath the steam nozzle, making sure the nozzle is inserted into the pitcher. Open the steam release knob and leave it open until the steam clears. Close the knob.
Remove the boiler cap and the filter holder. Empty the filter basket. Wash the filter holder, filter basket, carafe and lid, cup adapter and overflow grid in warm soapy water. You can also place these pieces on the top rack of your dishwasher. Use a damp washcloth and wipe down the espresso machine and filter ring.
