Coffee maker was purchased in Dec. 2010. It does not fill a cup when brewing. It barely pumps now. Have cleaned it twice with no results.

USING YOUR PERCOLATOR
1.Wash the Percolator thoroughly before using for the first time.
(See "Cleaning Instructions" section in this manual.)

2.Remove Cover, Basket, Spreader and Pump Tube. Use cold, fresh
tap water to fill Percolator. Fill according to markings on inside
of Percolator for number of cups desired. Use cold tap water -
the automatic brewing cycle is timed to begin with a cold
water start.
NOTE: The bottom of the Pump Tube Spring marks the maximum
capacity of the Percolator.

3.Wet Coffee Basket to help keep small particles of coffee from sift-
ing through. Place Basket on Pump Tube. Add desired amount of
regular or percolator grind coffee to Basket.

4.Place Pump Tube with Basket into Percolator so bottom of tube is
set into Center Well. Place Spreader on top of Basket and snap
Cover onto Percolator. Attach cord to Percolator and plug into
standard household 120 volt AC wall outlet. Brewing begins
within seconds and continues at a cup-a-minute speed

5.When coffee brewing is complete, percolating will stop. The
Percolator automatically switches to "KEEP WARM" setting to
preserve fresh-tasting coffee at hot, ready-to-serve temperature.
For best flavor, remove Coffee Basket, Spreader and Pump Tube
when brewing is completed.

Hello -

Regarding any coffee maker - some of the water in the reservoir is turned into steam during the brewing process resulting in a smaller volume of brewed coffee.

As for the Clean notice, it may just mean that the coffee filter basket needs to be cleaned. We wash ours every time after we brew coffee. Coffee residue builds up in the filter basket during use.

Best wishes.

Water has been fed back into the main pump. It is at the bottom of the unit. You need to disassemble this and clean the pump out with cleaning alcohol. Once the pump is filled with the cleaning alcohol, shake it around until most of it is out of the pump and then let it dry overnight.

I had the same problem, and it turned out it was the top needle that was clogged. I used a safety pin to clean out the needle and it worked again . . . I descaled immediately, just in case it needed that too. I am back to coffee goodness!

This occurs occasionally if the unit needs cleaning or you are brewing a new pot of coffee immediately after emptying a hot pot of coffee.
Run a cup of vinegar through the coffee maker twice, run at least 2 pots of clean water through to rinse the vinegar out.
This should clear the problem until it needs cleaning. The suggested frequency of cleaning is every 30 pots, but this varies depending upon the type of water you use.

the coils are super heating, and condensation of your water is vanishing faster than it's brewing. It sounds like your coffee pot is ready to go to mr coffee heaven

Just use vinegar. Fill the reservoir with white vinegar, put a pot or big bowl under the spout, get ready as if you were going to brew and then press BOTH the one cup and two cup buttons together.

Run the vinegar through again when it's done, and then run clean (filtered, preferably) water through twice. You're done.

Try cleaning it with pure vinegar. 3-4 times just keep running it through the machine.

run 2 cups of vinegar through the coffee pot brew it do it twice. this will clean the calcium out. then rince out out and brew one batch of water to clean.

I have this problem with a 4 cup model. 4 cups in, 2 cups out. I cleaned it twice with vinegar (with a filter in place). The first time didn't seem to help, but the second time I got about 2.5 cups out, along with a bunch of old grounds that I think had been sucked into the pump. Ran water through it twice, and now it gets to about 3 cups.

I think the problem is just that the pump is clogged with grounds. If vinegar makes yours worse my guess is that a big piece got dislodged and is now blocking the tube. More vinegar might help.
