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.

'Leaks' are usually caused by overfilling either the water reservoir or the coffee basket or by coffee grounds interfering with a seal.

Make sure you perform a complete cleaning on your coffee maker making sure any contact points which need to seal are free of coffee grounds.

Instructions for removing the grinder and filter baskets are contained within your manual.

overflow problem possible causes: 1) water is over the "10" marker, 2) no filter in basket 3) too much (or too fine) of coffee in the basket -- does not drain. Also make sure the "spring" on the bottom of the basket is not stuck (the one that lets you remove coffee carafe without dripping coffee.

had same problem..i took the basket holder and door off and gave the basket slider a good cleaning along with other internal parts. now works fine

I think the main problem with this machine is that the grounds fly all over inside when grinding and combine with the steam and hot water and eventually gum up the moving parts. This causes the latch for the filter basket to lose its grip sometimes and the door pops open during the brewing cycle...I was trying to take apart the slides to clean them out and made the mistake of removing the small screw underneath the left slide. Then the spring popped out and it took about an hour to get it back together, very frustrating. I ended up bending one end of the spring into a slight hook with a needle nose pliers so it would catch better on the "nub" that is connected to the side button. The best way I figured out to clean the slides so far is to blast them out with compressed air periodically for preventative maintenance. I use one of those cans normally used to dust off electronics and insert the straw into the slides.

there is two little plastic pieces sticking out of the bean holder and on the coffee maker where the bean holder goes there is 2 holes, take the bean holder and put one piece of plastic in the coffee maker holes at a time and it should fit just fine...

Make sure the slot between the grind basket and filter basket is clean and free of grounds - then inspect the area near the grinder motor - use the brush that came supplied with the Cuisinart to clean that area out. Once thoroughly cleaned, try one more time to Grind. Let me know if it works.

Vinegar instead of WD40 - I am pretty sure a good portion of the DGB-600's have this problem, but that is hearsay.

I have had the Cuisinart DGB-600BC for a bit over a year. The coffee grinds, and then sometime during the brewing cycle, it will go, "beep beep, beep beep, beep beep..." on and on.

I think I have traced the problem to the latch on the top lid that you open to access the bean hopper. I believe the latch sticks and doesn't close the lid tightly enough. It will appear to be closed, but the latch isn't all the way in place.

So, there is a small screw on the inside of the latch in the lid. Carefully unscrew this, remove the screw, latch, and the small spring. Remember which way the latch faces.

With a warm damp paper towel, clean the latch and the slot in the lid that the latch goes into. Reassemble, and make sure the screw is not so tight that the latch doesn't move freely.

This should solve your problem.
