First thing is to look at the spray head and make sure all the holes are clear. Take your delimeing tool and push it in the hole as far as you can where the spray head was, and push it in and out about 5 times. Now leave the spray head off, and with the unit unplugged, pour 10 cups of water in the unit and let it flow out. Repeat this 2 more times. Replace the spray head and plug the unit back in. Wait 30 minutes and then make a pot of coffee.
