Product review (1 stars): Another Negative Review for Miele
I too have been disappointed with Miele.  They are expensive which is fine as long as the experience is great - of the product and of the service.  I find my Optima dishwasher's performance to be poor and Miele's Canada's service to be the same.

I consistently have water marks on the handles of my stainless steel cutlery.  For some reason they thought sending me a new cutlery tray that was exactly the same as the old one would fix the problem.  It did not.  They now say that this is a problem with ALL dishwashers even though the watermarks are exactly where the cutlery contacts their esteemed cutlery tray.

Based on the poor service I have received and the inability of the dishwasher to clean cutlery w/o staining I do not recommend Miele.  Please send Miele a message and DO NOT BUY A MIELE DISHWASHER.
