Answer to: Brewer makes intermittent chugging sounds...slowly dribbles coffee?i 'm on my second keurig system 350. i had the same problem. you have to take a paper clip or the maintenance piece and see if any grounds are causing the problem. that did not help mine. i did the fresh water and descaling with poor results. finally i sought customer care. they sent a replacement machine ( you send holder part back) within 5 days on federal express. but would you know today the replacement started leaking from the bottom. i believe its the water holder because it stop releasing water in the cup. please call customer service for your machine.
