Question about KitchenAid KCM511OB 10-Cup Coffee Maker
Keeps giving me "Err4" and will not work. Any solutions?
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.

The button jammed solution is from the manual and hasn't worked for me. The problem for me was that moisture got onto the circuit board. I had to disassemble the coffee maker. Do this at your own risk. You'll need a phillips screwdriver.
There are four screws on the bottom of the machine that allows the bottom plastic to be removed. By shifting the exposed metal plate downward, you should be able to pull the faceplate that holds the circuit board that holds the LED lights and buttons. Carefully disconnect the two cables attached to the circuit board, one is bigger than the other.
At this point, there whould two plastic anchors you can push away from the edge of the board to release the circuit board. I tried a hair dryer to completely dry the board but this didn't work. I warmed the oven to 200 degrees for about 15 minutes and then turned the heat off. I placed the circuit board on a thick cookie sheet into the oven and left it inside the oven for an hour.
Inspect the circuit board to make sure it's completely dry. Then return the circuit board in it's plastic housing and reconnected the two cables to their mounts. Reassemble the plastic housing to the rest of the coffee maker. Replace the bottom plastic cover and replace the screws.

A button is jammed. Unplug the
Coffee Maker, press each button
several times, then plug the Coffee
Maker back in. (If the Coffee Maker
has been stored or used in a cool
environment, warm the unit to
normal room temperature before
doing this.) If “Err4” appears again
on the display, repeat this procedure
