First thing to try is a descale. Run the machine normally using it (as if making a cup of both types) a couple of times with a 50/50 mix of white vinegar and water. Leave the machine off but uncleaned overnight. run a couple of cycles with just water, and if there is still a slight vinegar taste then run a cycle with a teaspoon of baking soda in water, then flush with just water again. If this doesn't solve the problem, try again with 75% vinegar. If still not working, there is either a control board problem (may be solveable), or the valve/solenoid that stops/allows the water is sticking, almost certainly solveable by taking that apart and cleaning/lubricating. Definitely solveable by replacement. Let me know what you get after a descale if no luck. Hope this helps :)

i had this same problem. the solution is simple if you are a little bit handy.
there is a bad valve inside. i called Whole Latte Love where i bought
the machine and ordered a Steam Valve complete - Compact Frame
its part number GA-%0345.R and two O-Rings
the valve that comes with the machine is plastic and the new one is a brushed metal casing. my guess it will last for 10 years!
two screws on the back and the machine is open
near the front, by the steam wand, with a hose attached coming from the heater, is the valve, attached to the knob on the side
two more screws and the valve wrapped in a plastic housing comes out.
open the plastic housing, remove the insulated hose to the steam wand
and the water/steam plastic hose that comes in. replace the valve, hook
up the two hoses, but back in housing and you're done. attach back to
knob on the outside, put back together and in 30 minutes, the Titanium
is like new. no leaks.
it sounds daunting but is pretty easy and beats sending the machine
back for repair. i can't go a morning let alone a month without coffee
from my Gaggia. once repaired, the coffee is hotter too.

Water leaking in the DGB-600 is mainly caused by heated water escaping from its proper path. There is a rubber grommet on the underside of the upper part of the coffeemaker. (It contacts the lid over the filter basket when the front door is closed.) The design in this area is very poor; the grommet does not seat properly in the fixed part of the coffeemaker, and heated water seeps out. Also, the heated water tube that comes up through the cold water reservoir is actually in 2 pieces. One goes inside of the other, but there is no seal. It is a loose enough fit that some steam escapes, condenses on the inside top surface of the coffeemaker, and then finds its way down to add to the leaking. I completely disassembled my coffeemaker (3 of the screws in the upper compartment are hidden under small circular plugs that look like they are part of the plastic surface), and used high temperature automotive RTV sealer to help the rubber grommet seal better, and to seal the 2-piece hot water tube. Works great now! But I must say that I have seen better engineering in childs' toys!

Andy15 - Thanks - you encouraged me to do this myself. I made a video as I did my repair. The video making was more work than the replacement of the steam valvle. Please check out my video if you have have to make the same repair. Also - the technical support from WholeLatteLove was great. http://www.youtube.com/watch?v=8UgVBoFd5aE

My XP7240 has the same problem. I went through all cleaning cycles and the filter in the boiler still gets clogged up with coffee oils. This causes back pressure and blows the boiler seal out. Easy replacement if you can turn a screw driver.
Part number for Seal: MS-5015004. You might as well change the Jack too. (the part that slides into the boiler that compresses the ground coffee. (this is a redesigned double seal unit) Part Number MS-0697072.
Both these parts you can get at http://www.krups.com/Tools/Contact/Contact.htm choose your country and email the parts list. Mine cost in Australia $27.00 including shipping.
Good luck.
