Hi, Our coffeemaker wasn't getting the water into the espresso carafe. I've taken apart the inside and found a blockage between where the water is heated and where it exits in a tube area that comes to a tee. However, when I cleaned it out a small rubber washer came out and I don't know where it came from. I need a diagram that will show me. Now, the water goes very quickly and I can't stop it to use the steamer. Thanks.
