Query: Great for Different Risers BUT DON'T PUT IN DISHWASHER!!!

I really like this because my husband gets up 2 hours earlier than I do and I used to have to make a separate pot so it would still taste good. This keeps the coffee fresh tasting for a few hours. BUT - do not put any parts in the dishwasher or you will be sorry. It will ruin the delicate mechanism, oxidize the filter and make the pot look old and filmy. I ruined a good one but since I bought another just like it, I just rinse it usually and add a little soap now and then when the residue is visible.
