"Why is my machine so loud?"에 답변Bought a new Keurig model 475, noisy and annoying. Get this: I called tech support and held the phone to the noisy machine. The rep said that it should not make the noise she heard and promptly put in an order to send me a new one, at which time I should remove a certain vital part from the faulty one and send it back to them. PS, the new makes the same noise. I give up.
