When you've prepared your espresso and pressed start, the correct amount of water (depending on how many shots you selected with the Dose button: 1 (~ 30 ml) or 2 (~ 60 ml) will be dispensed. The hot water is forced through the coffee grounds that you put into the filter basket and tamped.:
It should take 20-30 seconds for either 1 or 2 shots to be dispensed.
- If less than 20 seconds (ie. it comes out too quickly): decrease the grind size and/or increase tamp pressure (15-20 kg or 30-40 lb of force).
- If more than 30 seconds (ie. it comes out too slowly): the coffee is ground too finely, so increase the grind size. You could also reduce the pressure of your tamp. Additionally, the filter basket may be blocked. Use a pin to unblock the hole(s). Lastly, the machine might need to be descaled
