Why does espresso leak around the portafilter on my Gastroback 42636 Coffee Maker?
If espresso runs out around the edge of the filter holder or the portafilter comes out of the group head during extraction with your Gastroback Coffee Maker, ensure the portafilter is correctly inserted into the group head. Rotate it to the right until the handle is past the center and securely locked in place. Also, clean any excess coffee grounds from the rim of the filter basket to ensure a proper seal in the group head. Always ensure the filter basket and portafilter are dried thoroughly before filling with coffee, tamping, and inserting into the group head. If there is too much coffee in the filter basket, trim the dose using the RAZOR™ dosing tool after tamping.
What to do if espresso only drips from my Gastroback 42636 Coffee Maker?
If espresso only drips from the portafilter spouts of your Gastroback Coffee Maker, indicating restricted flow, it could be due to several factors. The coffee may be ground too finely, so try using a slightly coarser grind. There might be too much coffee in the filter basket, so lower the dose. The coffee could be tamped too firmly; aim for a pressure between 15-20kgs. Additionally, the Dual Wall filter basket may be blocked, so use the fine pin on the cleaning tool to clear the outlet hole on the underside of the filter basket.
Why is my Gastroback Coffee Maker not making hot enough coffee?
If your coffee is not hot enough when using the Gastroback Coffee Maker, the cups may not be preheated. Rinse the cups under the hot water outlet and place them on the cup warming tray. If you are making a cappuccino or latte, the milk may not be hot enough. Heat the milk until the base of the jug becomes hot to the touch.
How to get crema with Gastroback Coffee Maker?
If your Gastroback Coffee Maker is not producing crema, it could be due to stale coffee beans. Try buying freshly roasted coffee with a “roasted on” date. Also, if you're using pre-ground coffee, make sure you are using Dual Wall Filter Baskets.
