Our coffee maker is only brewing half of the amount of coffee it should. Half way through the brewing, it shuts off. We've cleaned it with vinegar, but it still happens intermittently. It's actually happening with 2 different coffee makers--the Cuisinart Grind and Brew and a Gevailia coffee maker. (We switched to a different machine after having problems with the first one.) Any ideas?

Have you cleaned lately, put in an empty filter and fill with cold water with a tablespoon of white/clear vinegar. Run the brew cycle, empty pot and while still worm fill with cold water again with out vinegar. Than check filter to see how much hard water chunks are in the filter. Repeat with and without vinegar tell filter is clean. One question though is there a lot of steam coming out of the top during the brewing cycle if so inside there is a tube that may be cracked, broken or came loose, have to look inside. requires opening or disassembling unit to check. REMEMBER when taking apart UNPLUG unit first.

Have you tried cleaning your coffee maker? If not just fill half of the carafe with white vinegar and let it brew. Keep basket in during cleaning but no filter needed. After running the vinegar through the brew cycle, fill the carafe with plain water and run fresh water through about 3 to 4 times. I do this every 4 to 6 months. I have a light on my coffee maker that lets me know when I need to clean it. I hope this helps.

Believe it or not, this frequently happens when there is calcium scale build-up in your coffeemaker's water line. The coffee make will make it through the brewing, but then shut off if it thinks the flow was too slow--which is nearly always due to built up calcium scale.

All you have to do is run a few pots of white vinegar through your coffeemaker to get all the scale out of the waterline; I'll usually mix half water, half white vinegar and run the brewing cycle (no coffee in it, obviously). You'll see the scale come out in your coffee filter. You can run the same pot of water-vinegar mix several times, and then run a couple of extra pots of *fresh water only* to rinse out the descaling vinegar mix from the water line.

Voila! your coffeepot will start working again just like it should.

You might as well sanitize the whole unit. Fill the carafe half with water, half with "cleaning vinegar." Run several brew cycles, pouring the hot vinegar-water mix back into the reservoir. Then empty the carafe, and fill it with fresh water, and run several brew cycles to rinse out all traces of vinegar.
I suppose you could use white vinegar, but the cleaning vinegar has a higher acidity.

use vinegar 70% to water 30% leave to sdoak then rinse through a few times till vinegar taste goes

"Scale" is deposits of minerals, etc. normally found in water. Boiling a container of water (in a pot, or coffee maker in this case), leaves small amounts or "deposits" of these minerals on and near the actual heat source. If not removed, they can slow brewing time and more importantly, adversely affect the taste of coffee.

Descaling should be done at regular intervals to prevent this from happening. Your machine lets you know when to perform the descaling task. There are a number of products sold in your supermarket that will do this for you - but one of the least expensive; and just as effective - is to use white vinegar. Here's how to do it:

1) Drain your Keurig coffee machine over a sink.
2) Fill the machine with undiluted white vinegar.
3) Run the brew process at least four times, pouring the cups of vinegar back into the coffee maker.
4) Optionally, let your Keurig coffee maker sit for a few hours, then run the brew cycles again. Pour the vinegar into the sink and drain any remaining vinegar.
5) Fill your coffee maker with fresh water. Run multiple brew cycles with fresh water each time to thoroughly rinse the machine before returning to normal use.

That's it!

I know this will help & good luck. Please rate my reply - thanks!

The best way to clean a machine like this out is to actually run a full empty brew of a half water half vinegar solution. This will completely clean out the lines inside the machine and freshen everything up quite a bit. After you run the full empty brew of the solution make sure you run at least 2, maybe 3 full brews of just water on the unit. This will ensure that all vinegar is flushed out of the system, and will help clean it as well. Of course the vinegar won't hurt you if it isn't flushed all the way out, just makes it taste quite funky. But 2 flushes with plain water is almost always enough to completely clean it.

Of course when I say an empty brew, don't put any grounds or coffee filter in the machine, just run the water and vinegar through the machine as if you are brewing a full put of coffee.
Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.

try running vinegar and water half way through the unbit then ket it sit for about a half of an hour then turn back on. if it seems like it helps do this a couple of times

Let a half caraffe worth of distilled white vinegar sit in the water reservoir for about an hour. After the hour, turn the coffeemaker on and let it brew the vinegar until a small amount of vinegar appears in the caraffe. turn the coffeemaker off and let it sit for an additional 20 minutes. Then turn the coffeemaker back on and let it brew the rest of the vinegar. Then run a full caraffe of plain water to flush the vinegar out. If the self-clean light remians on - unplug the coffeemaker for 20 minutes or longer - if you unplug it for any less than 15 minutes, the coffeemaker will not reset itself. You should be good after that - as long as you do some sort of vinegar/water cleaning once a month henceforth.

Cuisinart Coffeemaker Decalcification Process

Run 2 cups distilled white vinegar and 2 cups water through the system - brew it like it was regular coffee. Then run plain water through the coffemaker to rinse the vinegar out and make sure the decalcification was successful. Repeat as needed. Don't forget to remove the charcoal water filters first.
