Hi, water does not seem to flow through the coffee dispenser normally. It then leaks inside the machine or drip tray. I replaced the large rubber o-ring and cleaned the dispenser, I also readjusted the grinder and dose controls but I am still having the leaking problem. I have maintained the machine properly and have descaled the machine. The brewer was replaced in December. I would prefer not to have to take it in to a repair center to spend another $200.00. Any help would be greatly appreciated. Thanks, Dori Saeco Italia sup0201

Re: water leaking from coffee dispenser
Hei dory may be this can be helpful.Inside the machine take out the brewing group on the back panel there is asmall metal piston with 2 small orange rubber o ring.Try to replace that(is not easy since the position)were the o ring are locate is very unconfortable but is something i believe you can do it.That one is the main connector between the inside and the conjunction with your brewing group.

Take the brew unit out when the machine is off and cold. With your finger, check the well next to the large gear on the inside of the machine. This is the gear that fits in the back of the brew unit when it is in place. That well may be clogged with fine coffee grounds and some mildew build up. You might notice that after brewing, very little water will has been flowing into the drip tray. Take a Q-tip and push it through the hole at the bottom of the well to remove the coffee ground buildup. The excess water after brewing will flow through normally now and not behind the brew unit.
I had a problem on my Tassimo T65 where water was entering the bottom drip tray through the small hole at the rear. It seems many people have this problem but after researching on line there is little help although I found on this sit how to take the coffee maker apart and from that thread the possible cause for my own issue.
So if your machine seems to be leaking from the small drain hole to the rear of the drip tray try this before you think it is either in need of specialist repair by Bosch at a cost almost the same as a new machine or before you start to take it apart and have a look yourself.
CAUSE - The water is coming from the drain hole because the pressure valve at the top of the machine is blocked with calcium deposits through prolonged use without descaling sufficiently.
SOLUTION - Purchase a good quality coffee machine descaler. Sit the whole coffee machine in a tray or large oven tray so you can collect the overflowing descaler throughout the process, it's not economical to waste this solution. Remember to clean down and dry the coffee maker each time.
Use at least half strength descaler do not water it down more than 1:1
Follow the descaling process by inserting the yellow disc and holding the start button down for 3 seconds.
Repeat this process several times, recovering the fluid leaking in to the tray and cup or container. If you start to see small lumps being dispelled in to the cup try to remove these for further descaling.
After several cycles you should notice that the leaking or flow of water from the bottom drain hole becomes less until it stops. To force the dissolving scale out of the pressure valve try running the normal clean cycle but with the descaling solution, the flow is longer and will help flush the restriction.
After a number of descaling and clean cycles the leak or flow from the drain hole will have stopped, if not continue till it does.
Note: I ran cycles for about 2 hours with periods of rest to allow the solution to do its work.
Now the leak or flow has stopped clean out the reservoir and replace with clean water and run at least 4 clean and rinse cycles.
i hope this works for you and now enjoy your coffee.
I really sounds like the machine is working properly (water flowing properly) and either the filter material is too thick, or the coffee is too fine, or the flow control mechanism is failing to open properly. (For reference, I use Bunn filters in mine as they are taller and allow the water level to rise deeper in the basket before overflowing.)
Some things to look at: (1) make certain that you are using only one thickness of paper filter, (2) that you are only using coffee designed for your coffee maker (drip grind usually) and that (3) the mechanism is opening properly (not gunked up with dried coffee or whatever).
When the machine is done brewing some water is relieved into the drip tray. This is the pressure relief. Some coffee residue is also taken into the drip tray. This is normal. As long as nothing is under the machine your OK.
Your problem is probably the boiler leaking. Its located just above the drip tray in the center of the machine. When it starts leaking it goes into the drip tray or on the counter top. If you can remove the top, you can see if the boiler is leaking. There will be a white line between the 2 halves of the boiler.
HI The coffee residue is the result of the machine relieving its pressure into the drip tray. When it relieves its pressure, a little coffee residue with some water is released also, otherwise you would have an explosion of coffee inside your machine. If you are getting dry coffee in the drip tray you are getting an overcharge and that is not good. If you get residue under the drip tray, you have a blocked drain in the back of the machine just above the center of the drip tray.
If the grounds are really wet and not looks like a round firm cake, you need to use coarser grist on the grinder. The water in the drip tray is coming from the brew unit. The o-rings are not holding the pressure inside because the sieve is clogged. It could also be that the o-ring are dirty, then the brew unit needs to be disassembled and cleaned.
A good way to controll if the grist is too fine, is to watch if the coffee is just dripping from the outlet. Then try adjusting the grinder until the coffee flows evenly. You can also hear if the pump works harder during brewing.
Possible areas are the steam valve leaking or the boiler valve housing is leaking. I suggest

run a 50/50 mixture of white vinegar and water thru your system.may have to run it twice,should clear it up if its a mineral clog. be sure to run a few cycles of clean water afterwards to clear the system
