My Cuisinart DCC-1200 takes a long time to brew now, the coffee is weak, and the self-clean button flashes each time. My Cuisinart DCC-1200 takes a long time to brew now, the coffee is weak, and the self-clean button flashes each time. I've had it for about 4 years.

Over time, Calcium will deposit on the tubes and containers which get in touch with water.
The calcium can also impact the function of the Heating elements in the percolator tube.

Try Decalcifying with Designated Products.
Usually, you do this by diluting the product, fill up the water reservoir, and cycle on the machine, without cofee of course,
Pour out the water. It will probably look troubled.
If the water does not start percolating, just let the water reservoir stand with the decalcification product for about 30 mins. don't leave it in overnight, because these products are slightly caustic to remove the Calcium, but it could damage parts if left in the machine overnight.

Repeat the process until the water starts running faster and/or gets hotter.
don't forget to rinse with regular water. 2 Cycles rinsing should suffice.
See manual for suggested products or just use 1/4 cup of Vinegar diluted with Water per caraffe. It will smel like vinegar while you do this, as the vinegar evaporates with some of the steam.

I would repeat this process every month or so if you use your machine daily.
