I get a build up of grinds in the area shown. They build up under the 'diagonal' tube that is in this area. water tehn leaks into the drip tray or out of it. Can you advise what may be the problem? I clean it often. Thank you so much.

All coffee makers do this over time from calcium, lime, and mineral deposits building up inside the tubes and heating coil. Fill the reservoir with a 50/50 mixture of water and white vinegar and run a normal brew cycle, turning it off and on if necessary to completely empty the reservoir. Repeat this 2 or 3 times with fresh mixture of vinegar and water until it brews the reservoir empty without the need to cycle the power. Follow this procedure with plain water 2 or 3 times to clean the vinegar out. This should get it working like new again. It's best to use distilled water for brewing coffee as distilled water does not have the minerals that regular tap water has and therefore will not clog up the machine.
Yes, you place the spring into the tube at the back. When you replace the basket holder, make certain you reach in behind the holder and guide the spring into the proper place on the holder. (Otherwise the spring will be forced to a permanent bend and not work as well. Can't find replacements for this spring on Cuisinart's website).
As for why it pops out better now, when you removed the basket holder and cleaned it, you also cleaned the plastic guides on each side. In normal use, these guides acculuminate coffee and tend to get sticky or gummy. When the door pops open, the sticky rails grab the guides and slow the sliding action.
Cleaning them restores the clean guide rails to slide open on. (Next time you clean the basket holder, remember to reach in and wipe out all the inner parts, including the plastic rails that the basket holder slides out on. These get coated with coffee as well. And the place around where the grind basket fits over the ground basket. This area always gets sticky with old coffee. Just use a wet paper towel and clean everything. (But remember to be careful when you reinstall the basket holder so that the spring fits back properly.
I do not know what model or make you have but it sounds like the problem is inline after the pump, check the grind and tamp if semi machine, if auto then it is being blocked either the brew unit screen and output tube or the grind, it is also possible that there is buildup just after the pump, try descaling the machine.
you need to run a few pots of straight white vinegar through the machine to clean out the lime build up in the tubes. the first time you do it, after it starts to pump the water, shut it off for a few hours and let the vinegar sit in the tubes. after doing this run a few pots of cold water through before making coffee.
If you fill two esspresso cups at the same time it should be the correct size. But if it is weak, see below... For one cup, press the small coffee button to start. Press the button again when the desired amount of espresso is in the cup to stop the flow. if it is too watery but the correct amount see below.
If the espresso is too weak push the coffee grinds slide switch inside one notch finer and make another 3 cups. If the flavor does not get strong in 3 cups then there is an anomaly happening. The brew unit upper filter has gunk clogged behind it to a point where the pressure (230psi) of hot water trying to get through the gunk pierces a small channel through only a portion of the filter screen. All the water is running through only 4 or 5 holes in the filter screen. This eddy allows hot water to pass most of the grinds without extracting flavor. It's the same as if you clogged a sink strainer then pushed the blockage off part of the strainer. The water goes around the coffee not through it. The path of least resistance.
Remove the upside down stainless steel filter on the brew unit- Remove the screw using the allen key that came with the machine. It goes through the little finger nut on the top of the brew unit. Turn it counter-clockwise (lefty loosy) and the filter will come off from underside. The area behind the filter screen has to be cleaned of any coffee residues. Also check thew creme valve. It is under spring tension accessible from the top of the brew unit by removing two screws holding the long pipe on top. be careful not to let the spring shoot out and loose the creme valve. It looks like a plastic rivet on the other end of the spring. Clean out the entire channel by rinsing. Use a pipe cleaner for dried on grinds.
Note: the finer you set the grinds the quicker it clogs the filters. Increase the use of cleaning tablets when you grind finer coffee. A clogged brew unit is almost impossible to clean even for the most handy of people and the last I checked a new brew unit is well over 200 bucks! Good luck!
Try this, adjust the grind to a coarser setting atleast 2 numbers, then remove brew unit and look behind at white plastic valve, there is a small chamber under valve make sure chamber is clean and that the small discharge from chamber to drain tray is also clear. Then remove shower screen from brew unit and clean if necessary, also check the tube from the shower. Reinsert and test.
Two questions: 1- Is the coffee grounds wet or dry? 2- Does the spout drip water when the machine is just heating up? If the grounds are dry then the brew chamber is not getting any water. Turn machine off, let it cool down, then remove brew unit. Behind the brew unit there is a white valve with 2 red o-rings(sometimes black), if you look closely there is a small lever between the o-rings, get a small screwdriver and gently lift lever and spring, if water came out then the problem is in the brew unit, unscrew the stainless steel screen which is under the large red O-ring on the brew unit and clean, also make sure the tube on the unit is clear. If the hot water spout is not dripping when the machine is heating up then you're good.
It is endemic to this unit - condensation builds up in the grind chute, which makes the grinds stick to the walls of the chute. Decalcifying with vinegar/water helps, but only in an indirect way - by keeping the inside tubing clean, decalcifying generally allows the water to flow through the machine without obstruction. Inside tubing that has calcium, lime deposits built up obstructs water, and makes it flow through the machine slower - when water flows more slowly through the machine, the machine steams off the water at a higher rate, hence more condensation builds up in the grind chute walls.
Generally, i have found all Cuisinart coffee and espresso makers to be high maintenance to a greater or lesser extent, but the Grind-n-Brews have the highest cleaning/maintenance requirement.
Ok, If you pull out the waste water tray and bean tray, along with the brew unit ( by pushing the lever that says push) turn the brew unit upside down and you will see a layer of waste coffee grinds on a circular metal plate, just rinse it under a cold tap, dry it off and reassemble
Also you may want to try rinsing other parts of the brew unit and give it a general clean if there are any other build-ups of coffee grinds :)
