Hi Rose,

My mother-in-law had a similar problem and I found that a transparent film coated the entire inside of the reservoir (you can see if yours does too by feeling the inside of the tank as deep as you can reach). Once I got it clean, it began making full cups of coffee again just like it did when it was new.

Here's how I got it working for her. Her tank has a fine meshed stainless steel screen over a "small valve" on the bottom of the tank secured with 3 small phillips screws. I removed the screws and took out the valve. The screen "looks" clear - but the same transparent film on the tank walls was coating the screen, too. As a result water flow thru it is significantly reduced - so it takes longer for water to pass thru it - resulting in "short" cups of coffee. The screen must be cleaned or replaced. I opted to clean it with an old tooth brush and soapy water. I then flushed the soap and the film from it while holding it under a stream of water from the faucet. I looked at the volume of water passing thru the screen to be sure it was cleared well. When happy with the flow, I resecured the valve to tank (after washing the tank in the top rack of the dishwasher as per the instructions on the underside of the tank lid).

The film is a type of growth - like algae. To help prevent regrowth or slow it down; do not let water sit in the tank all the time. Pour only enough water in the tank that you'll need for the next 8 to 12 hours - better yet - dump the remaining water out after each "batch" of coffee you need to make. Do not let water sit over night or for any longer than necessary. Be sure to WASH the TANK regularly in the top rack of the dishwasher - as per the directions.

I hope this helps & good luck!

Why does the water I put in the maker run out the bottom

Sounds like it has a leak in the tank or the hose. Unplug the coffee maker and turn it over. See if you can remove the bottom cover. Make sure the coffee maker has not been on and is cool to the touch!
Underneath will be a tube and heating element. Make sure the tube is connected to the water reservoir and that there are no holes or cracks in anything. It could be that someone dropped it and cracked the plastic somewhere.

SAYS COFFE READY PUSH LARGE CUP AND A COUPLE OF DROPS COME OUT THAN SAYS FILL AND PUSH STEAM HAVE DONE AND REDONE SEVERAL TIMES STILL NOT GETTING A CUP OF COFFEE TOOK TANK OUT AND CHECKED FOR FLOTATION IT...

Hello.

1 Perform the initial setup on the coffee maker. Make sure the coffee maker is not plugged in. Slide the empty funnel into the funnel guides, fill the decanter with cold water, open the lid and pour water from the decanter into the brewer, put the decanter back on the base, then close the lid and wait three minutes for the internal tank to partially fill. Open the lid, fill the decanter with cold water again, and once more pour the water directly into the brewer. Put the decanter back on the base and wait for water to flow out of the funnel and into the decanter. Once it has stopped flowing, pour out any water that is in the decanted and plug in the coffee maker. Press the on switch to turn the coffee maker on and heat up the water in the tank.

2 Ensure the lid is completely closed. If the lid is open, the Bunn coffee maker will not brew coffee.

3 Check the see how much water is in the water tank. The Bunn coffee maker will not begin brewing coffee if less than 20 ounces (4 cups) of water is present in the water reservoir tank.
4 Delime the coffee maker. Unplug the coffee brewer and allow it to cool down. Remove the sprayhead by turning it by hand and set it aside. Insert the flexible deliming tool into the sprayhead tube until all but two inches are showing. You may need to twist and force the tool to go in. Slide the tool in and out several times to loosen lime buildup.
Check the sprayhead for lime buildup. If there are flakes of minerals, they can be removed with a toothpick. Scrub the sprayhead with soap and water. Rinse the sprayhead with water and replace it in the coffee maker. Pour water into the water tank and turn the coffee maker on, allowing water to run through without making any coffee. This will flush any lime fragments through the system. Empty the decanter

Thanks.

Coffee won't brew - lights turn on - clock works - clicks little.

2 years old I would pitch and buy a new one.

Cleaning generally won't help a machine that does not work.
Heating element has probably burned out.
(I am not talking about the heating pad for the carafe!)

For future reference for all the coffee drinkers out there:
Simple quick way to clean a drip coffee maker is use Vinegar.
Let it brew through the system as you would water.
Discard and run fresh water through the system to clear out the vinegar residue left behind. (Make SURE the system has cooled first before running the fresh water through!)

For those that have hard water and the coffee tastes funny.
Try a small pinch of salt in the filter basket ON top of the coffee grounds. This will soften the water and hopefully take the bitter taste away.

Guess it is possible large enough calcium deposits could block the hole in the holding tank to prevent the water from percolating to the filter basket. You may wish to check this before tossing. Last minute thought before pushing the post button.

Good luck!

Self cleaning the quisinart coffee maker

I always use a mixture of 50:50 of cold water and white vinegar to help clean the internal parts of any minerals and scaling.


Unplug the coffee maker first, then add the water/vinegar mix to the reservoir.

Place a new, clean paper filter in the basket to help catch any deposits that will be dislodged and cleaned from the coffee maker.

As far as having the coffee pot dry, there is no need for that. I do tend to wait about 15 minutes to let the cleaning mixture disolve any deposits in the main water reservoir and then I turn on the coffee maker and let it process the water/vinegar solution through it.

Once it's done, turn off the coffee maker and discard the solution in the pot. And rinse out the coffee pot/carafe with clean, fresh cold water. Remove and throw away the used paper filter element andrinse out the basket with warm water and put it back on the unit.

Now fill the coffee pot/carafe with fresh, clean water and pour that into the coffee maker's water reservoir. Put in a new, clean, paper filter and turn the unit on and run a plain pot of water. This will help to clean out any remaining residue and clear the unit of the vinegar taste and odor.

Now you're all set to start making fresh tasting coffee again. I always recommend using filtered water for the best tasting coffee, as the taste is a direct result of brewing temperature, water purity, and the coffee you use.

Hope you find this Very Helpful and best regards!
