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 best for espresso brewing and richer crema. Storing beans properly is also important, more information 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.
The Pippa is particularly picky when it comes to having all of these factors perfect. New users of the machine are suggested to work on pulling and perfecting their technique by pulling double shots with the double filter basket. Single shots are notoriously hard to pull and should not be attempted until double shots can be pulled with the machine consistently.
Note: Although the machine featured in the video below is the Rancilio Silvia, the Pippa is similar enough that the process described will work for both machines.
