Open, hold, close – with every milk drink. Along the way it absorbs heat from the valve, catches milk splashes and is occasionally handled with wet hands. It’s normal that after a few years it no longer looks the way it did on day one.\u003c\/p\u003e\n\u003cp\u003eIt only becomes critical when it no longer grips properly. This replacement knob carries part number A430004284 and fits the Cellini and the Giotto.\u003c\/p\u003e\n\u003ch3\u003eWhen it’s time to replace it\u003c\/h3\u003e\n\u003cp\u003eThe knob is due when its internal seat has widened and it slips on the valve spindle. When it shows cracks, especially around the spindle seat. When it gives way as you close it, so you need more force than before. And of course after a fall in which something broke off.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eKnob, control part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation location\u003c\/th\u003e\n\u003ctd\u003eon the outside of the machine, on the spindle of the steam and water valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eRocket Cellini and Giotto\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eScope of delivery\u003c\/th\u003e\n\u003ctd\u003eone knob\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003eA430004284\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVersion\u003c\/th\u003e\n\u003ctd\u003eOriginal spare part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eRocket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWho it’s for\u003c\/h3\u003e\n\u003cp\u003eFor owners of a Cellini or Giotto with a worn or broken knob – and for anyone who wants both sides to look the same when only one needs replacing.

If it’s stiff, the cause lies in the valve, and the new knob will wear out just as quickly as the old one. When a knob is being replaced anyway, we replace the clip and the O-ring at the same time – they cost little and are easily damaged during removal.
