Generally, I'd start with one part white vinegar to three or four parts water. You may need to run it throught the machine a few times if it's badly blocked

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.

If the code does reappear, 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.

Their toll-free telephone number is 1-800-541-6390.

Unfortunately the carafe is obsolete. KitchenAid has stopped production on the carafe.

ERR 4 in a Kitchenaid coffee maker indicates a button is stuck in place. Please be sure to check all of your buttons and see if any are stuck depressed into the machine.

If this is not the case, I would suggest contacting Kitchenaid Customer Service to see what other options may be available.

ERR 4 simply indicates that the computer is recognizing a stuck button (a button have been depressed for more than 10 seconds time). Please double check to make sure that no buttons are still depressed into the machine.

There is no programming function that allows the beeping to be turned off on a Kitchenaid Coffee Maker.

There might be some residue in the machine, you can try using some ScaleKleen which is activated citric acid, use a very small amount diluted in water(about 1/4 teaspoon). Run brew cycle with solution, after cycle complete, rinse reservoir, and run about 4 cycles with fresh water. This will clean out your machine.

I had a similar problem with Err 1, Err2, and Err 4. To resolve Err 1, if you have room, remove the coffee filter and coffee, pour more "warm" not hot water into reservoir. If you have 4 cups cold water add 5 cups warm. Then start coffee maker and let it run thru. Then drain coffee pot and start over to make coffee with tepid water. Err 1 indicates the coffee maker temp sensor is too cold from room temp or water temp.
Err 2 is a result of cleaning. First question "Did you remove the charcoal filter?" The charcoal filter can be removed form the filter stick by prying two tabs away gently and removing the filter for removal. The filters can be purchased @ www.Kitchenaid.com
One pot run thru with descaler can loosen scale and make sensor go "blind". Just run a full pot of clean plain water thru one maybe two times. A pot solution should be a solution of 1/4 pot WHITE vinegar, 3/4 pot clean cool water. Run this thru once, then two clean pots of fresh water as if you brewed a pot of coffee. NEVER USE CLR WITHOUT RUNNING NO LESS THAN THREE CLEAN WATER POTS THRU MAKER!!!! This is so you can continue to enjoy drinking coffee, nothing like a cup cleaning you out!
Err 4 is simple, you have a stuck button. Unplug maker and gently press each button making sure they aren't stuck in.

I found that the following clears the "clean" word that is flashing:

  1. Hold MODE and the + button for about 5 seconds.
  2. After the coffeemaker chimes 2 times, release the buttons.

Hopefully, the clean message will go off.

As an aside, the warmer plate is so awful looking. I am replacing this coffee maker (KM222) with another (and cheaper) one.

You will need to investigate the reason that it's not heating. Check the element and the thermal fuse that should be on the element for continuity. If the fuse has failed replace it and try it again. If the element has failed you may be looking at buying a new coffeemaker.
