No Crema or Bad Tasting Shots
Typically, issues with crema or the flavor of the shot do not indicate a malfunction of the machine. Instead, this indicates that an adjustment needs to be made in the brewing process or that different beans need to be used.
The following articles review the different variables and offer solutions:
It is important to use fresh beans, typically beans roasted within the past two weeks are best. Light and medium roasts are ideal for espresso brewing and richer crema. Storing beans properly is also important, more information on that can be found here. If the behavior persists after reviewing these factors then the machine may need to be cleaned. Lack of cleaning can cause burned or bitter flavors, or create flow issues which can result in a weak shot.
