"Expensive." star star star star_border star_border We wanted a coffee maker minus the sludge leftover in the mug. That’s happened. I am disappointed that when I open the top to fill empty out the used coffee there is a torrent of condensation pouring over the other side of the machine. I have to stand it in a cloth to prevent it sitting in a puddle. Also the flask stains badly. It is glass and I’ve never seen glass staining from coffee ever! Previous was a cafetière and that never stained.Now have to scrub it deliberately to clean off the staining. The time the flask is kept in the heat could also be a variable not a set 30 mins. Mrs Bailey - 26 October 2020 support_agent A note from the team We're sorry this didn't work as expected. We'd suggest waiting for the machine to cool down before emptying the basket. We're not sure why you experienced so much condensation, and as the flask is glass we're not sure how it's become stained. In terms of the keep warm function on most coffee machines this is set to a standard 30 minutes which is a safety setting after this time it auto switches off, but we're sorry you were disappointed it couldn't be set to a longer time.
