Product review (3 stars): how to fix the spray arm
We've had our new dishwasher for a couple of weeks and it does a great job of cleaning the dishes (our Kenmore only "worked" if you washed the dishes ahead of time).  The flat rack at the top for cutlery is actually a very nice feature.

But there are some strange features, as though the folks at Miele never actually lived with a dishwasher.  For one thing, you can't tell when the thing is actually running.  It's very quiet, which is nice, but it makes the absence of a little red light all the more inexplicable.  Instead it beeps you when it's done, and won't shut up until you come and open the door.  (Just what we all need; more bossing around).

My main reason for writing this review is that I figured out what to when the middle spray arm falls off.  1.  Pull out the middle rack (just pull and lift; there are little tabs on the end that you have to lift over.  2.  Put the rack on a flat surface, upside down 3. Fit the spray arm so that round end of the spay arm fits INTO the semicircular channel in the middle of the rack; at the same time, make sure the little hole at the other end of the arm fits on to the little peg thing at the end of the rack.  (sorry for the lack of visuals).  4.  then put the rack / spray assembly on end, so that you can tap the spray arm gently but smartly, so that it goes into the semicircular channel and stays there.  5.  then put the rack / spray back;  you have to angle it around the end peg stopper things, but it's not hard.

It would be nice if any of this were mentioned in the manual, but, as I say, I don't think anyone at Miele has ever actually used or owned their own machine.
