I thought I'd update on the dishwasher saga.
I ordered the Miele G 4920 SC via the link above, and got a confirmation. After a couple of days I received an email from the shop saying they did not after all have it in store and they did not think they could get it before the end of January. I was slightly irritated but had been putting all 4 of my dc to work on washing and drying up duty, and thought that this was quite good for them to do for a while.
However, a week or so later I got another email from the shop saying they now couldn't guarantee they would get the Miele I wanted at all, and anyway it no longer had the £50 cash back offer.
So, I cancelled the order, looked at all my options and thought for a bit. I was so sold on the Miele brand, and the cutlery tray that I ordered it through ao.com, for about £100 more. They delivered it two days later, and I've now plumbed it in (very easy to do) and it works beautifully.
I am very pleased with it, I am trying not to think too hard about the expense, and keep telling myself that it will still be going strong in 20 years time and is therefore worth every penny.
But the weird thing is that all my children (aged 9-16) pulled faces and said they had been enjoying doing the washing up after supper every night. They had been putting the music on loud, taking it in turns to wash, dry and put away, and had an enjoyable 'together' 15 minutes each evening. Who would have guessed! And yes, I know it would not have been nearly as enjoyable for them if they knew it was a permanent arrangement, but still, it was an unexpected few moments of family harmony.
