Easily maintain your appliance with original Philips parts. This grease is used to lubricate the central brew group. It is recommended to apply it monthly, or at least every two months, to ensure proper operation of the brew group. Proper lubrication allows the brew group to move smoothly. Insufficient lubrication may damage the mechanism and, in extreme cases, prevent the selected beverage from being prepared because the machine can become jammed. Lubrication is recommended after cleaning the brew group. The brew group can be cleaned manually under running water or with a higher-pressure water jet. Based on our tests, the brew group can also be placed in a dishwasher using a very low-temperature program, at a maximum of 30°C. The tube contains 5 g of grease. On average, this is sufficient for 1 to a maximum of 2 lubrication applications.
