Cleaning how do i clean the tank. the coffee maker has been sitting for two years

Start with the simple stuff. Does it have a detachable water tank? These sometimes have sensors which trip out if the tank isn't positioned properly. Try removing it and using a dry cloth wipe clean the underside of the tank and the mount surface it sits on. Refit the tank, fill it and retry using it.

putting vinegar in the tank OCCASIONALLY wil help to keep the tank and associated tubes clean, but it shold be noted that doing this too often will corrode the aluminum tubing used in the coffee maker. put about a cup and 11/2 of vinegar in the tank and run the coffee maker, followed bu a double run of pure water to clean out the vinegar. should only be done about once a year as vinegar is a mild acid.

why question to all of this is with a "self clean" button, why doesn't it every tell you to clean it..... ??

This is telling you that it is time to clean the coffee maker. Press the minute and hour buttons at the same time and hold untl the light stops flashing. Take out the water filter and fill the water tank to 10 cups and add 2 cups of white vinegar. Put the water tank back in, without the water filter. Take out the permenant coffee filter. Turn it on and leave it until about half the water goes through. Turn it off. Let it sit for about an hour, then finish the job. Then, run 2 pots of clean water through. You are good. It will notify you to clean your system every 40 pots or so.

You will need to pull you coffee maker out and take the top off and clean inside the water tank. Someone has put coffee from pot of old cold pot of coffee back threw. or something loke this. just clean inside and out. clean coffee maker and pots. hope this helps
