Sorry for the delay in response but I just read your complaint. I had similar water leakage issues and mistakenly replaced a bunch of stuff without stopping the leaks, until I discovered the real problem; the O ring seal that the water reservoir sits in located under the reservoir where it mates with the machine. Easy to replace and cheap. No leakage problems since I both replaced the O ring and started the routine of not taking off the water reservoir to fill it, but leaving it in place and filling it from a bottle. That technique does not any wear at all on the seal ring and so it won't leak in the future.
The item is called a "Saeco-water inlet valve gasket" , has a part number of NM05.006 and costs $7.50. I purchased it from Services Unlimited located at 650 N. Cannon Ave. WH-305, Lansdale PA 19446; phone 215-361-7000 Fax 215-361-7434, e mail [email protected] but you can find it at any authorized dealer, I am sure. I ordered two and with shipping the cost came to $21.50.
You can request a fax with a parts diagram and listing, which I found most helpful in diagnosing issues and see where stuff goes..
A second cause of water leakage is the drain set back in the machine that is behind the brew group which gets clogged on rare occasion. Remove the brew group and take a paper clip and insert it in the drain and make sure it drains freely into the drain pan.
A third cause is that you are not cleaning the removable grinding surface in the brew group. If it gets clogged, the hot water cannot pass through it and it just kinda squirts all over inside the machine, and you get weak coffee since most of the water is not being brewed.

Hope this helps you..

Hi
Any time you run out of water when the machine is operating, you will need to prime the machine again through the wand not the brew head. Turn the knob on the left and then turn the machine on. The pump should get quite after a few seconds and water should come through the wand. If it doesn't you need to turn the machine off. Get a asperator bulb or you can use a turkey baster. Fill with water and stick on the end of the tube going to the pump . Turn the machine back on ( the knob should still be open), and squeeze the bulb to force water into the line. If the pump changes tone, turn the machine off. Remove the bulb and put the tube back into the tank . Try the machine again.
