When I had to change the sealing ring on my Druckdampfgarer after 6 (!) Years almost everyday because it was now leaking from one to another day, I noticed that he had a Fissler number. So I needed a new rubber seal is not expensive at Imperial buy, was able to buy it in a large department store. The new seal held for almost four years. The subsequently purchased on the Internet ring made limp after only one year, as then any other replacement also. While in the manual of the device that you should replace the gasket every two years, with newer devices even annually. I have the impression that here comes consciously less durable material for use by the manufacturer of the sealing ring. If you still the enormous price increase over the years with reckons, I can no longer talk of cheap unfortunately. The environment can probably not be useful. My hope for warranty service I was also buried immediately. It is a consumable item, it was from a seller. (I could also not complain about the fuel that would no longer be for a ride in the tank, even though the gas station would have to be two-year warranty to me by law.) Now, we have for years set up so that we use the steamer almost daily and have reduced the burners on two. Whenever then the ring is leaking, has to be improvised to delivery a few days. A replacement ring I trust micht not buy before. I have great concern that the then in the drawer so outdated that it only holds half a year. The withdrawal of the two stars has only to do with it. The ring is of course to fit 100% because he is indeed original installed by Miele. He costs the Replacement Part almost double! Seen from there, it is about to see an great bargain. But compared my costs for the sealing rings of the past ca have risen (the first 6 years) on now about 20 annually 1.20 annually. Since the deal is in a very different light.
