A hob espresso maker is a compact device that can brew a few cups of espresso in minutes. The espresso maker is relatively simple to use and more cost effective than an espresso machine. While it is fairly obvious you'll need to clean out the basin and carafe after each use, over time your espresso maker may need a deeper cleaning. Failure to give your device a thorough cleaning can lead to odd-tasting coffee or cause it to have an unpleasant, burnt smell.
Disassemble your espresso maker by unscrewing the top chamber from the base.
Locate the perforated filter plate on your espresso maker. This is in the bottom section of the top chamber. A small rubber gasket surrounds the plate. Remove the gasket using your knife--place the knife between the outside of the gasket ring and the inside of the espresso maker. Gently pry inward until the gasket comes free.
Turn the top chamber upside down gently, and tap it lightly on the surface of your table or counter. This should knock the filter plate out of the espresso maker. Inspect the plate for rust. Rub the plate gently with the steel wool pad to remove stubborn build up or rust stains.
Fill your sink with warm water, and add a small amount of mild dish soap. Place all the disassembled parts into the sink and allow them to soak for several minutes. Gently scrub the inside of the pot with a soft sponge. Rinse all parts thoroughly with water. Dry completely with a towel.
Reassemble the espresso maker by placing the filter back into the top of the pot, then pushing the rubber gasket back into place around it. Screw the top and bottom sections back together.
Inspect the rubber gasket for damage. If it appears melted or particularly discoloured, it may need replacing. Prevent the burnt smell from returning by cleaning the maker regularly and using medium heat rather than high. High heat can quickly burn your coffee.
