Coffee Question Redux

[GarGus]

Don't visit this room often but this has me stumped.

For about the last week and a half our coffeemaker is turning out lightly flavored water instead of coffee.

I'm in charge of the morning coffee experience in our household and my routine didn't change. However, here is what I have tried.

First thought--bad batch of beans. Went to a bag I had brewed several times which I knew to be "strong" Kenya AA and still came out weak.

Second, tried more beans in the grinder--no change.

Third, tried different filters/different brands of filters--no change.

Fourth, ran cleaning cycle with vingear through coffeemaker--no change.

I think the next step is trying a new coffeemaker but wanted to ask if anyone has experienced anything similar and, if so, how did you solve it?
