SOURCE: Cuisinart Grind & Brew not using all the water in the reservoir

I was having problems like this and then I read on a different string on this website that people have had success by flushing the system numerous times (sometimes up to six times) with vinegar. I took out the charcoal filter and flushed once with vinegar but only saw a small amount of improvement. I was out of vinegar so I used Lemishine mixed with water and it went from making one cup to making a full pot with one flush.

Call Hamilton Beach Product support 1-800-851-8900. They will send you a whole new tank (gasket cannot be replaced, if it fell out, the tiny plastic part holding it in broke off, I know, mine did the same thing) For a whopping price of $5.00, that's right $5.00 to cover shipping, they will send you a whole new tank. I love Hamilton Beach. They truly do stand behind their products.

The spring goes at the top of the stem, under the filter basket. This keeps tension on the basket, so it will pop up when you remove the cover.
