To clean your ROK, simply remove the portafilter by turning to the right, knock out the coffee ‘cake’ into a bin and rinse off any remaining coffee grounds that may be left on the body. Occasionally wash with soapy water but do not put the ROK through a dishwasher. The salts will destroy the high quality finish. The milk frother, however, is dishwasher safe.
Occasionally, you may want to maintain your ROK more thoroughly. You can do this in 2 ways -
With the portafilter removed and the ROK upside down, press the centre of the round rubber diaphragm (with the small holes). You will see that this diaphragm deforms allowing you to remove it from the edge. Clean the diaphragm with warm soapy water and dry thoroughly before replacing it, and also clean and dry the inside of ROK from the underside. Replace the diaphragm before usage.
Undo the double top bolt which attaches the plunger to the metal arms. With the bolts off the arms will fold back allowing you to remove the plunger and water cylinder. Clean thoroughly with warm soapy water, dry thoroughy and re-assemble.
To clean the portafilter, remove the inner basket (taking care not to lose the metal ring which keeps it in place) and rinse under running water.
This depends a lot on how firmly you press the arms down. In normal usage expect between 5 to 10 bar
Pre-warm the portafilter - put it in a cup of boiled water for a few minutes (make sure the ROK body is warm and not out of a cold cupboard etc).
Warm up your cups with some hot water before you use them also.
After some time there may be a build up of oily coffee residues on the surface of the bayonet mechanism. This can be solved by cleaning the surfaces with a cloth soaked in warm soapy water. Follow the instructions in 'How do I clean my ROK' paying special attention to cleaning the area where the chrome portafilter attaches.

The coffee grind should be specifically for making espressos. The grind should be fine. If it’s coarse, the water will pass through too easily so it won’t create enough pressure. If it's too fine it might be too dense and create too much resistance.
