At the end of each day
- Clean the group head and portafilter thoroughly of all loose coffee grounds.
- Place the rubber disc in the portafilter (nipple upwards)
- Place the handle in the grouphead
- Press the on/off button to flush with water for around 10 seconds
- After 10 seconds empty out any loose coffee grounds that have accumulated on top of the disc
- Repeat this process as many times as required (no less than 5) until the grouphead is clean. This should be done at least twice per day.
