This causes the system to fill with water, which is essential for the machine to work properly. -- Do not use the SENSEO® machine in combination with water softeners based on sodium exchange. -- Philips strongly advises you to descale this SENSEO® regularly. If the machine is not descaled in time and according to the procedure described in chapter ‘Descaling’, this may lead to technical failures. -- After unpacking the machine, never put your SENSEO® machine on its side.

If you did intend to start the descaling cycle, do not interrupt this cycle but let the appliance operate until the water reservoir is empty. Make sure that there is enough water in the water reservoir and that the water reservoir is placed properly. Empty the water reservoir and shake it a few times to release the float. Clean the water reservoir with hot water and some washing-up liquid or in the dishwasher. [. . . ] Make sure the intensity switch on the front of the machine is in the right setting. When you adjust the switch, the volume in the cup is also adjusted (HD7833, HD7831 only). If you cannot clean it properly with the washing-up brush, put the pod holder in the machine and descale the machine (see chapter CALC).
