Usually it means the cooling system has air in it.
Or the thermostat opens suddenly.
I am assuming the engine is not running hot.

here's a new one http://www.thebigcoffeestore.info/send.php?s=aHR0cDovL3JvdmVyLmViYXkuY29tL3JvdmVyLzEvNzExLTUzMjAwLTE5MjU1LTAvMT9pY2VwX2ZmMz0yJnRvb2xpZD0xMDAwNSZjYW1waWQ9NTMzNjkxMzYwMyZjdXN0b21pZD0maWNlcF9pdGVtPTExMDc0MjI5NTc4MSZpcG49cHNtYWluJmljZXBfdmVjdG9yaWQ9MjI5NDY2Jmt3aWQ9OTAyMDk5Jm10aWQ9ODI0Jmt3PXJzcw==

Hi,

Here is a tip that I wrote that will give you some things to try that will helpyou get your Keurig coffee brewer workingagain.

You may need to run a pot of white vinegar and water (50/50) through several times to flush out the line and heater. Make sure that the plate under the pot is getting very hot or it won't pump water from the reservoir. Hope this helps!

On a Kitchenaid coffee maker, ERR 4 indicates a stuck button. Please double check to make sure none of your buttons are sticking in place and "freezing" the coffee maker. If you can not find any obvious problems, I would recommend calling Kitchenaid Customer Service to see what options may be available to you.

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

We are going to buy a new coffee pot a different brand. We took the 1st one back and now this one
isn't working with an err4 which no one knows what it is but everybody has it!! You want to charge a fee to fix it why??. We paid $60 for that coffee pot and expected it to work longer than 2 years.Your add reads let our experts solve your problem for free. So I click on Chat live now and up comes a page to charge for it so forget it, we will go to a different brand.

Had the same problem after cleaning. ERR4 is the result of moisture in the electronics. FIRST UNPLUG COFFEE MAKER. Get a long philips screwdriver and remove the 4 screws at the bottom of the coffee maker. Pull the bottom off and carefully unclip the front panel. The circuit card is simply clipped in so it removes nicely by unclipping with your fingers. Now take a hair dryer and dry out the circuit card. Carefully plug the maker back in and verify that the LED nolonger reads ERR4. Reassemble and your back in business!

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.
