Figure out how to pull apart the group head to give it a good clean (at least removing the shower screen).
All machines need that occasionally, work machines get absolutely rank.
The part of an espresso machine where the water passes through the coffee. Called a brew group in the automatic machines (and they can get mouldy and horrible). Should at least remove the shower screen or filter screen from the group and scrub out the old rancid coffee tar with a cloth/toothbrush.
Pouring a shot of plain water should smell and taste like clean excellent hot water.
