If your Mr Coffee emits a loud screeching sound during or after cleaning cycle and nothing stops it.....don't get a new one or take it apart and try to figure it out. Unplug for about 10 minutes and it resets itself.

SOURCE: Coffee maker not working

Hi,

Here are some of the most common problems that can cause your drip coffee maker to stop working:

  • The power cord or on/off switch can go bad. In either of these cases, it's best to get a pro to replace it or buy a new coffee maker -- replacing it improperly can lead to a fire.
  • The one-way valve can get clogged open or closed. You can usually fish out the debris that causes this problem with a toothpick.
  • The tubes can get clogged with calcium. This is especially true of the aluminum heating tube. The normal way to solve this problem is to run vinegar through the machine once, and then run two batches of water through to clean out the vinegar.
There are two problems that are nearly impossible to fix:

Failure of one of the heat-sensitive switches

(This is The coffee maker's temperature sensors)

Failure of the heating coil:

(This is the The coffee maker heating coil)

Because it's nearly impossible to get replacement parts, you probably have to buy a new coffee maker if one of these problems disables your machine. Now, when you make coffee tomorrow morning, you can do so with a new appreciation for exactly what's happening inside.


Goodluck,

There is a post on descaling already but I think the unit just doesn't have enough water in the resevoir. See several of my other posts on how to fill the machine.

Sorry to read about your problem, I hope this helps you out.

If your brewer is not brewing the full amount selected, it may be caused by the following:

* The exit needle is clogged by coffee grounds or cocoa mix. Please refer to the K-Cup Holder cleaning instructions.
* The brewer may need to be de-scaled. Please refer to the de-scaling instructions.
* The removable water reservoir was removed during brewing. Place the water reservoir back onto the brewer and perform a cleansing brew without a K-Cup.

If this does not work you can contact Keurig at 1-866-901-2739 or Keurig.com
You do have a 1 year warranty, and if you are out of warranty. They will give a discount on a new unit.

Keurig coffee maker makes loud noise single cup brewer. Make loud noise prior to brewing.
The brewer should be de-scaled at least every 3-6 months. Scale is harmless, but if left unattended, it can hinder optimal brewer performance. De-scaling your brewer regularly helps maintain the heating element, removable water reservoir and other parts of the brewer that come in contact with water. Better water quality and water heating means a better cup of coffee, tea, hot cocoa or iced beverage. We recommend de-scaling your brewer at least every 6 months (every 3 months if your water has a high mineral content). The de-scaling process involves using 48 ounces of undiluted white vinegar.

Take 48 oz of white vinegar. place in tank. pretend you are making coffee (Do No Use K Cup). let the water fill you mug. then empty that mug. Do it again until tank is empty. then let sit for 4 hours.
Then fill with fresh water to the top. let that tank of water run thru. towards the end taste the water.
If you taste vinegar..use more clean water, until the taste is ok.

Mr. Coffee CG13 12-cup coffee maker. Have used it
There is high temp tubing that may have come loose or become dammaged fromheat or the coil that heats the water may be leaking if you are using strong cleaning chemicals to remove scale from the unit. The bottom is held on with screws. Remove these and look to see what is the source of the leak.

Water coming out of steam nozzle not coffee output when making coffee
Sounds to me there might be a blockage on the brew unit, and since the pressure is so high it is going through the bypass. Clean the screen and tubes on the brew unit.

Another possible reason for backup - using paper/gold tone filter at same time. If not:

You have not missed anything. Unplugging for longer than 16 minutes (has 15-minute memory) is the only troubleshooting you can perform. Call Cuisinart to find out if you are still in warranty. All electronics have a failure rate. Cuisinart's is acceptably low, but their coffee makers are the least reliable of all their products. The basic problem with electronic coffee makers is that coffee makers produce high heat, and high heat kills electronics and melts plastic. At least Cuisinart has a 3-year warranty - higher than the industry standard.

Let me put it another way. All coffee makers have a high failure rate. As many Cuisinart coffee makers that break down, the non-Grind-and-Brews still have a 91 rating from Consumer Reports. Consumer Reports doesn't give ANYTHING a 91 rating. A lot break, but you probably won't fare much better by switching to a different brand. The problem with a Cuisinart breaking down is that an expensive unit broke down - you wouldn't be upset if your $15 Mr. Coffee broke every year. The law of averages is on your side - a 2nd Cuisinart will probably last longer.

Frothe the milk?
he trick to this is making sure you have steam comming out of the wand and not water. To do this, make sure you get the steam started before you begin. To get a light foam that will not deflate, hold the wand just under the surface of the milk. You should hear a steady, high pitched noise and you should not hear the splatter of bubbles popping on the surface. Popping noises mean that the wand is too high in the milk and your froth will not hold up. A low pitched noise from the cup means that the wand is too far down in the milk. This will heat your milk (for hot chocolate), but will not give you a good foam. Good luck!

Delayed brewing
The problem is in the sensor that tells the coffee maker when the brew cycle is complete. This is a heat sensor that's clipped to the heating element. The sensor gets overly sensitive and shuts things off too soon. Since schematics and parts aren't available for this unit, it's pretty much junk after it starts to fail. You can remove the sensor, but this creates a major fire hazard. My advice is to pick up a good percolator and forget the drip units. The Grind-N-Brew makes excellent coffee, but they barely last out the warranty and the cost of replacing them mounts up. I've gone through two (same problem with both) and it's no longer worth it to me.
