Macine was packed away for 1 year not used that often bought home finally unpacked it turned it on it brewed not even a 1/4 cup then stopped now it wont pump water out at all

!!!!FIXED!!!!

I know this an old question, but I finally fixed mine. Hopefully this will help someone. I have a PSTX Mr. Coffee (10 cup) maker.

Allow me to provide some background first ...

I started a clean cycle, following the instructions in the booklet exactly. I used 4 cups of white vinegar and pressed the clean button. Easy, right? The reservoir emptied about 2/3, the clean light began blinking and an audible (steady) alarm sounded. I waited for 2 hours for that audible alarm to stop, but it never did. Finally, I unplugged the coffee maker, plugged it back in and tried again. Same results. By this time, I figured I had run enough vinegar through it to properly de-calcify the unit, so I repeated the "clean" steps numerous times with just plain water. Same results. I realized that I could still brew coffee; only thing is, the darned clean light would keep coming on when I pressed brew. Surely, I did something wrong or there would be an answer on the web. I searched many answers, but none fixed my problem. So I decided to call Mr. Coffee (US: 800.672.6333 or Canada: 800.667.8623). I navigated through the menu and found the troubleshooting section for cleaning. The automated voice said, "Place 6 cups of cleaner solution or white vinegar in the reservoir...."

Stop the presses! Did she just say 6 cups? The manual clearly states 4 cups. Also, that's what everyone else on the web is reporting.

So I tried it, and I only used water (since the pot was still relatively clean) - 6 cups of water - pressed the clean button. This is what you SHOULD expect:

1. Place 6 cups of cleaner solution or white vinegar in the reservoir
2. Press the "clean" button.
3. When approximately 2/3 of the solution has brewed through, it will [apparently] stop brewing - the "clean" light will begin blinking (but there should NOT be any sort of audible alarm) - let the maker sit; it's still working on the clean cycle.
4. The final 1/3 of the solution will brew through and the cleaning light will shut off.

This CONCLUDES the cleaning cycle.
Of course, you should just perform a few "regular brew" cycles with just plain water to clear out the vinegar (or cleaner solution) odor.

Bottom line: The manual screwed all of us! 6 cups, not 4!

Try it - Hope it works for you as well as it did for me.

1. Power off machine.

2. Using a metal paperclip, insert it into left side of top needle. It must insert at least 1" deep. Insert it into slot on right side and again from back of needle.

3. Remove KCup cradle. Separate bottom from top. In the top section, insert the paperclip up into bottom needle from the bottom upwards. It will not go all the way thru and this is normal.

4. Reassemble KCup cradle and reinsert it back into coffee maker.

5. Power on machine.

6. Brew a cup of water only. There may be coffee grounds in the water and these should eventually clear during the remaining steps. NOTE: A large cup brew cycle should output a full 8 ounces (235cc). Less means there is still a blockage

7. Empty reservoir and fill with undiluted distilled white vinegar. Repeatedly run brewing cycle until Add Water light comes on.

8. Make sure Auto-OFF is NOT set and let last cycle of vinegar remain inside machine for 4 hours.

9. Refill reservoir with fresh water and repeatedly run brewing cycle until the water is clear and odorless.

10. Set Auto-OFF, if preferred.

Mine just started to do the exact same thing. So I decided to clean it using the "Clean" program and just water. I put the brewer through the cleaning program 3 times - each time it would brew water from 12 cups to 8 cups, I'd tap the brewer on the countertop, it would brew from 8 cups to 4 cups, tap it again, and it would brew the remaining cups. So, I called the Mr. Coffee help line (800-672-6333). The most-likely problem is that the hose is no longer attached in the water reservoir. The help line suggested that I take it in to a service center. I live in Urbana, IL and the closest service center is in Oak Lawn, IL - 2 hours away from me!!
Here is my solution:
1) Buy another coffee brewer.
or
2) Smash your current Mr. Coffee brewer into a million pieces (this relieves stress) and go buy another coffee brewer (probably stay away from Mr. Coffee products).
Hope this helps.
Frustrated in Urbana

This may be one of two issues:
1. The pump is malfunctioning which can cause the internal reservior to not completely fill which causes issues during brewing. My unit dribbled random amounts of water instead of brewing for about a week before the pump died completely.
2. The puncture seal isn't in the right position. Open the Keurig fully so you can see the sharp puncture pin. Very Carefully push the black rubber gasket around it all the way up. Then pull it back down about 1/16". Brew a cup, if the problem continues, try sliding the gasket further down by increments of 1/32".

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. If self-grinding your coffee beans, ensure you are using the correct grind setting for an automatic drip coffee maker. (See instruction manual for coffee maker and/or grinder.)
3. Do not overfill tank with water. Use the marks on the side of the reservoir as a guide rather than those defined by another measuring method. This is because a "cup" in a coffee carafe is defined as 6 oz, not 8 oz, and in some cases as little as 5 oz as a cup. As such, a 12-cup machine actually produces closer to 9 standard 8 oz cups. (See your owner's manual.)
4. Make certain the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. It is extremely important to clean your machine with vinegar or as instructed by your owner's manual at least three times per year, more if your water supply is hard (prone to leaving water rings). A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew a pot of coffee, to produce "off" tasting coffee, or to clog and overrun the filter basket.
9. Ensure that the coffee machine is sitting level on the counter.

Run 1/3 caraffe vinegar and 2/3 caraffe water through the machine.
Dip-It is not the best cleaner to use with this coffeemaker - stick to distilled white vinegar.

If the cleaning fails to resolve the issue, and the unit was purchased in the last 3 years, call Cuisinart and see if you are still in-warranty.

Finally, I got my coffee pot to run through without stopping several times. To fix it I had to run vinegar through eight times! Never before has it taken so many cycles to clean out a pot. It is still spluttering a bit so today I am going to get more vinegar or maybe even CLR and run it through a few more times.

I have the same problem with the exact same coffee maker I have tried pushing the 1-4 cups button. That worked for a couple weeks, now it is back to only brewing half the water in reservoir whether I push the 1-4 button or not. It is very annoying.

i had the same problem, its the screen in the clear water container is plugged...i sprayed mine out and now i have no problems. it was plugged with coffee grounds.

Be sure the red rubber gasket is in place and clean (ridge side in) and bottom water cup is screwed firmly on to avoid leaking.
HOW TO USE:
1) Fill the bottom water cup with cold water up to the inside lip.
2) Set funnel into bottom water cup
3) Fill coffee basket with expresso grind coffee and level off. (Do not tamp or pack). Make sure it's filled to the top.
4) Place filter onto coffee basket and set coffee basket into funnel
5) Place brewer over bottom water cup and screw firmly into place.
6) Place unit with lid in the center of a microwave oven set on high for 1-1/2 minutes. If boil over occurs, reduce the brew time in 10-second increments until no boil over occurs.
7) Grasp handle to remove unit from microwave when finished brewing.
8) Remove lid and check the level of espresso in the brewer cup. Standard brew is at least 2 oz. If you don't have this level brew, replace lid and microwave on high another 10 seconds. Wait 20-30 seconds for bubbling to stop.
CLEANING/ADDITIONAL BREWING:
1. Under cold running water, unscrew the bottom water cup. CAUTION: It is normal for some water to be left in the bottom water cup. Both the coffee basket and any water in the bottom water cup will be extremely hot! If you prefer, allow the unit to cool for at least 3 minutes before unscrewing it.
2) To brew additional espresso, rinse Funnel, coffee basket and filter, then repeat brewing steps 1-8 above.
3) Parts are top rack dishwasher-safe -- hand washing filter is recommended.
