Insert the 1 CUP filter basket into the portafilter, followed by the supplied cleaning disc, followed by 1 cleaning tablet. 2. Lock the portafilter into the group head and place a large container beneath the portafilter spouts. 3. Ensure the water tank is filled with cold water and the drip tray is empty. 4. Press the POWER button to switch the machine off. 5. Press the 1 CUP and 2 CUP buttons simultaneously, then also press the POWER button. Hold all 3 buttons together for approximately 10 seconds. 6. The cleaning cycle will commence and last for approximately 5 minutes.

If your cleaning disc is without a whole in the middle, hardly any or no water should come through the portafilter.
