Just bought new Miele washing machine

Thanks to your very helpful advice I an antisipating the arrival of my Miele Paramount ( from John Lewis ) this Friday and I'm quite excited ( a bit sad really ). So once I have had it for a few weeks I will let you know how I get on with it. Mostly my washing machines last 6-7 years and although my Hotpoint Aquarius is still working it's so noisy!!! I've had the engineer out and he says its fine, but I can't stand the row any longer. At the moment Miele machines with the "honeycomb " drum come with 10 year free parts and labour warranty ...we'll have some of that said my other half. I have aquired truck loads of helpful advice to look after my new machine as I must admit as I never did with all my others. About 2 years ago I had to have a new drum in my Hotpiont , a bearing had "gone" , and the engineer told me to avoid Calgon as it can damage the door bellows ( I've not heard this before or since so it may be entirely wrong) so I use these sachets that come in a long narrow blue box ...I can,t find a name on the box ..just the word "professional" but I think they may be German. There was a sharp intake of breath when I showed my husband the Miele model I wanted but when I told him Miele reckon it should last 20 years and that I would have got through 3 £400ish machines in that time span he saw sense.

Thank you very much WASHER HELP.
