We have "inherited" an abandonded coffee maker, with the Capresso brand on it. No manual has been left with it. It appears to have a permanent filter in the coffee basket, as well as a separate filter (for espresso?) in the well where the water goes. No product number or serial number can be found, although on the bottom of the unit is a sticker which says: "CAPRESSO, elegance thermal household coffee maker. TM 437.01" Are manuals available for this product which can be downloaded?
