How to perform a clear water backflush

To keep your Oracle® Touch in top working order, we recommend performing a clear water backflush after every coffee-making session. This routine cleaning method helps remove any residual oils from the espresso paths. 
The first step is to empty the drip tray and locate the gray silicone cleaning disc included with your machine. 
Place the disc into the filter basket and then insert the portafilter into the group head. 
Next, press the 'Brew' button to start the flow of water into the portafilter. 
After 20 seconds, stop the shot that discharges water back into the drip tray. 
Repeat this step 3 or 4 more times to complete a clear water backflush.
