My 10 year old Phillips coffee machine, set for a double espresso, stopped grinding beans. It would "whirl" but only emit hot water into the cup, So I had to fix it. There are four T10, sheet metal type screws holding the top on. After clearing the debris inside the screw head, the T10 bit could turn the screw. Three shorties and a long one, ~2 cm, held the grinder feed cover. Inside the grinder export tube was blocked by coffee powder which backed up and prevented beans entering the grinder volume. There is a loosely held suspension spring under the grinder assembly but otherwise nothing extraordinary to deal with. Clear the jammed coffee powder, reassemble (careful returning the T10 screws into the plastic assembly,) and test. This short video shows how the ground coffee powder falls into the brew head: It had completely filled with coffee powder which explains why it became just a hot water dispenser. Happy caffeine every day! Bob Wilson
