I forgot to put water into my Mr. Coffee for a minute. When I realized it, I shut it off and poured in the water. When I restarted, it did not heat or brew.

I would just get a new coffee maker. The mr coffee coffee makers tend to hold up quite well and require minimal maintenance. Hope this helps!

All coffee makers use a thermal fuse which opens (interrupts) at a specific temperature, generally somewhere above boiling point and do not reset when cool.

They are designed to prevent fires if the thermal switch which cycles the heater fails and the heating element heats beyond its normal operating temperature.

These Chinese devices are poorly made and unpredictable in performance.

They are not user-replaceable since they are spot-welded on both ends; the only possibility is the replacement of the pre-assembled heating element/thermal switch/thermal fuse which will likely cost close or equal to the price of a new machine if at all available.

This morning when my wife went to make coffee. The clean light came on. we couldn't get it to shut off. She went through the clean cycle.The light came back on again. What should we do ?? Mr. Coffee...

I know this sounds like a pain but it takes a while to get that silly light to stop.
If you have problems call the 1-800 number below.
Decalcifying your MR. COFFEE® Coffeemaker Minerals (calcium/limestone) found
in water will leave deposits in your coffeemaker and affect its performance. It's
recommended that you regularly remove these deposits using MR. COFFEE® Cleaner
or vinegar. MR. COFFEE® Cleaner is available at many retail stores or by calling the MR.
COFFEE® Consumer Service Department at 1-800-MR COFFEE (1-800-672-6333).
1. Follow package instructions to prepare one batch of MR. COFFEE® Cleaner. Pour the
mixture into the water reservoir. Before decalcifying, remove the water filtration disk
from the machine.
NOTE: 4 cups or 20 fl. oz. of undiluted, white household vinegar may be used as a
substitute for the cleaner.
2. Place an empty MR. COFFEE® 10-12 cup basket-style paper filter
or MR. COFFEE® permanent filter into the filter basket and slide
the brew basket in place.
3. Place the empty decanter back in the unit.
4. Press the CLEAN button until the CLEAN indicator light turns on
(Figure 9). For your convenience the cleaning cycle is automatic.
The entire cycle will take 45-60 minutes to complete.
During the cleaning your coffeemaker will:
a. Slow brew approx. 3 cups of cleaning solution.
b. Pause for 30 minutes (the CLEAN light will remain on to alert
you that the process is active).
c. After 30 minutes, your coffeemaker will brew the remainder of the cleaning
d. When complete, the CLEAN light will turn off and your coffeemaker will turn off.
5. Discard the cleaning solution and rinse the decanter thoroughly with clean water.
6. Fill the water reservoir with clean, fresh water.
7. Place the empty decanter back on the coffeemaker.
8. Remove and discard the paper filter used during the cleaning cycle. If a Mr. Coffee®
permanent filter was used during cleaning, remove it and rinse it thoroughly before
replacing it in the filter basket.
9. Begin brewing and allow the full brew cycle to complete.
10. Repeat steps 5 through 9 one more time.

My Mr Coffee ADX20 coffee maker does not boil the water through any more. I would assume the main heating unit is bad. How do I replace the main heating unit?

You might have scale that formed on the heating element. This happens to all heating elements due to impurities in the water. I would try cleaning it a couple times to see if it helps first! Clean the mineral deposits from your coffeemaker every 80 brew cycles if you have soft water and every 40 cycles if yours is hard water. About once a month is good for a coffee maker. Pour four cups of undiluted white vinegar in the water reservoir. Place a paper filter into the removable filter basket, close the lid. Go through a brew cycle with decanter in place. Turn the coffeemaker OFF after THREE cups of vinegar have entered the decanter. Let set 30 minutes. Turn machine on and let rest of vinegard run through. Discard filter and vinegar solution, rinse. If this doesn't help the element is probably bad and from everything I have heard Mr. Coffee doesn't have't replacement parts for consumers. They only sell to "Authorized" repair shops. With that being said I have heard if you call the Service number 1-800-672-6833, and talk to an human operator, not the machine, they have sent out new units because of this problem. If that doesn't help Coffee makers are usually throw away items, I have recently purchased a pretty nice Mr. Coffee one from Costco for $30. Kohl's had one the looked a little different but all the same features for $55. So for like $30 you can get a new one, where if you could find an heating element it would be probably around $20. Just saying!

I Love my Mr Coffee, it used to be ready when I got up, now it takes 40 minutes for 12 cups to brew, is there something I can flush the lines out with or what?

It is likely that it is clogged up with scale. If you live in an area with hard water, especially well water, the calcium in the water is left behind when the water steams away. Take about a quart of regular vinegar and pour it into the tank you normally pour the water. Let it stand about 30 minutes and then run a regular cycle as if you are making coffee except without the coffee grinds in the brew basket. Keep pouring fresh water through it until you not longer smell vinegar coming out. It will put it back into normal running condition.

We have an FTX41 12 cup mr coffee maker. Suddenly all the water we pour in comes out the bottom all over the counter. What do we do?

Ours (FTX41) did this, made a pot of coffee in the morning just fine then a few hours later we went to make another and the water just poured out the bottom. I took out the 6 screws (4 philips and 2 torx under the rubber feet). When I took off the bottom one of the hoses to the heating element had come off. I put it back on and everything worked fine. It took about 15 min. to fix and put back together. Poor design on the hose connection, no clamps of any kind.

Not perking

I bought one used and almost threw it out until I found the manual online
I didn't realize there was a right way to fill and pre-heat the water first. Try filling the unit TURNED OFF waiting 3 minutes then try filling again w/ the crafe under for extra water coming out, then let heat for 15 min see if that works hope you haven't thrown it out yet!

Will not percolate. Water is poured, it heats up, no coffee brew

Bunn Home brewers don't perculate. They work the same way that commercial brewers do. Fillit with water, let it heat for about 20 minutes, then put your filter and coffee grounds in the funnel, pour a pot of water into the machine, put the pot on the warmer, and let the water run through. Then enjoy a nice hot cup of coffee.

How to use coffee maker

This type of coffee maker is made to keep hot water always ready to make another pot.
Pour water in ( at least 4 cups)then turn it on with the pot installed to catch the water. It takes a few minutes to get it hot . You might hear it heating. I can with mine.OK after the heating sound goes away put some coffee in the filter and in stall the filter.Now, fill the pot again (at least 4 cups) and pour the water in and put the pot ready to catch the coffee.It makes the coffee fast because it already heated the water from the first time you poured it in.When finished with the coffee just turn off the burner only.These types are made to stay on 24 hours a day.
I just turn mine off and let it heat up the water in the morning.

How do I program my Mr. Coffee ISTX95

I am sure abut this but most coffee maker work by pouring the amount of coffee you like to make.If it's a automatic then you have to put the coffee in it and pour the water also, then set the time you want it to start.Other wise just pour in after you put the coffee in and turn the switch on.

Mr Coffee stopped brewing

Sounds like there are a couple of problems -

First, are you certain that the coffee basket is clean? If the coffee basket has a valve on the bottom that allows you to remove the carafe to pour a cup of coffee, make sure the valve is clean. Being dirty would cause it to trickle coffee slowly into the carafe, and will hold coffee in the basket too long.

2nd, you may need to flush the water heating system as they can become corroded with precipitated solids from the water.
To do this, mix 1 part vinegar to 2 parts water in the carafe. Pour into the coffee maker and tell it to make coffee. Do this a couple of times, using a fresh mix of vinegar and water each time. Pour the used mixture down the drain.
When you feel it is clean, follow it up with a fresh pot of water. Then wash and rinse the carafe.

The coffee maker is now ready for it's next use.

I have a Mr Coffee MRCTB and it does not work

You don't. It stays in there inside the heating tank. When you put in cold water, it pushes out the already-hot water. Every year or so, you need to clean it out, or have someone do it for you. I just cleaned about a half inch of gunk out of one we have had at the fire station for about 10 years. Never knew we were supposed to clean it out...yuk. Tastes better now. Clean as a whistle! Also had to replace an overheat safety switch, $8.00 on-line.
