Coffee maker overflows

SOURCE: over flow

What we discovered was that coffee grounds had gotten into the cap of the coffee pot itself-plugging it so that the coffee was not running into the pot but all over the counter-very frustrating!! We took the cap off and really shook it under the water all different directions and got globs of grounds out-doing that once in awhile has gotten rid of the prolem we hope. We do have the problem of the machine shutting off several times during brewing-having to restart again and again. We cleaned with vinegar-hope it works.

An ERR 2 may be cleared by a simple reset of the coffee maker. This means unplugging the unit and plugging it back in. When powered back on, select a brew function to see if the error reappears. This may take a few seconds.

If it does, ERR 2 indicates an internal error with the computer of the warming plate. This may be covered under Kitchenaid's 1 Year Hassle Free Warranty. I would advise you to call Kitchenaid Customer Service to see what options are available to you. Repair is not recommended, as it is not cost effective for the company or the consumer.

SOURCE: When brewing, it steams and spits the water out

this is what happened to me, I didn't have the filter basket all the way down so the pot lid didn't open the valve that lets coffee flow so the coffee and grounds ran into the water resevior and plugged the filter, so I did the worst thing possible and took the filter out so the grounds got into the check valve that keeps the hot water going in the right direction. that makes it spit and sputter and brew slow.
after trying to flush it out forever I tore the metal plate on the bottom off and unhooked the rubber hoses (don't do this unless you have a needle nose pliers, you'll never get them back on) one should go to the brew head and the other is the water inlet, this has the check valve. you can tell which is which by blowing through them and seeing which one goes to the brew head. if you can blow through the other one the check valve is stuck open, I blew air into it with an air compresor and this forced the check valve shut and now it works fine. I know this is the same symptons as calcium deposits but I had cleaned it twice.
try flushing it with water first but sometimes it takes extreme measures

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. If self-grinding your coffee beans, ensure you are using the correct grind setting for an automatic drip coffee maker. (See instruction manual for coffee maker and/or grinder.)
3. Do not overfill tank with water. Use the marks on the side of the reservoir rather than those defined by another measuring method. This is because a "cup" in a coffee carafe is defined as 6 oz, not 8 oz, and in some cases as little as 5 oz as a cup. (See your owner's manual.)
4. Make certain the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. Clean your machine with vinegar or as instructed by your owner's manual at least three times per year, more if your water supply is hard (prone to leaving water rings). A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew a pot of coffee, to produce "off" tasting coffee, or to clog and overrun the filter basket.
9. Ensure that the coffee machine is sitting level on the counter.

I have a 1600 with the same problem. The problem is due to a poorly designed fit between the carafe and the drain plunger in the coffee basket. If you lift the carafe slightly, you will see the plunger has a long way to go. If you have the tendency to push the carafe fully to the back of the hotplate it makes this worse. OK, so now the fix, which worked for me. Find a small piece of plastic to glue to the top of the carafe lid. You just need a small dimple to push the coffee basket spring in further when you in sert the carafe on the hotplate. You should experiment a little first to see how thick it needs to be. Overall it's a poorly designed combination and someone needs a lesson in tolerancing.
