We have very hard water, and I've been using my gaggia carezza machine for about a year now without thoroughly cleaning the brewgroup/shower plate, etc. (I know, bad!!). I do run hot water through it after every shot, as recommended, but it's plugged up and no water comes out of that part now. I've got all the parts removed (shower screen, bolts, etc.), but CANNOT get the shower holding plate removed! I'm afraid I'll break the thing, but it's wedged in there tight. The picture in the manual isn't very helpful, as I cannot tell where they are placing the edge of the flathead screwdriver. Help!!!

They are most likely chrome plated brass and they will strip or break. The only chance that you have is to heat it. This may not be possible though if you dont have a soldering iron that gets really hot. You cannot use open flame or heat guns. If it does break or strip then you need to either replace the whole fixture for the drain connection of try to drill it out and use a tap to rethread it.
I had the same problem but it was not a new machine (about 1 year old). I found the solution by replacing the valve inside the group head. It cost a matter of a few pounds and very easy to fit. In the middle of the spreader shower plate there is a screw. Undo this and take off the shower plate and you will find a threaded bolt that has the thread that holds the screw you just took out. Carefully undo the bolt and the valve drops out. This is the part that I replaced. Replace with the new valve and re-fit the shower plate. Be careful not to overtighten the valve as it can snap. It worked for mine and has worked well ever since. It might be worth taking the current valve out and wash it then put it back before ordering a new one. It could just be blocked.
Remove the screw and shower in the head, check shower for blockage, if it is covered with coffee, hold over an open flame to burn out coffee (easiest way to clean it). If it is clean and you can see through all holes then turn machine on and press brew button, if not water flow, then remove 2 allen wrench screws and check spring and valve(remove carefully) then try the brew button, if no water then blockage is on the inside of the machine use the pic below to clear it will be on the top of the head.
I had a similar problem. Steam was fine, but just a drip out of the group head. The hoses looked fine, so I ended up taking apart the boiler. This really isn't too hard. You need metric allen wrenches size 3 and 5, a pair of channel locks and a screwdriver. You'll have to take all the wires off the boiler, so make sure you mark them before taking first. Remove the four allen bolts from below and you can take the whole boiler out. Removing the four allen bolts on the boiler will allow you to separate it and clean it. Mine was nasty. When I put everything back together, the pump sounded normal and I got normal flow from the grouphead. Hope that helps.
Hi there, it sounds like your boiler may be full of scale. There is a copper tube which runs from the group up inside the boiler which can get clogged up quite easily. When you take the group apart you will see that when you remove the shower plate and unscrew the bolt in the middle the safety valve and spring will pop out and then if you get a pipe cleaner or something similar and ram it up through the copper pipe. If this does not work then you may have to dimantle the boiler and give it a good clean out. Also although you say the pump is primed it could still be broken. All these problems usually come from scale though. If you get some descaler and try to feed into the boiler by pumping or running water out the steam wand this may free it up.

Of all of the gaggia machines I have worked on I have mostly seen clogged filter screens in the top of the brewing head. I am not familiar with your particular machine but look in the top above where the coffee goes and see if you see a shower screen up there. If so, the screen maybe clogged with coffee residue and stopping the proper flow of water through the coffee. Clean out any and all water ports and screens and around the rubber seal gasket where the coffee holding cup seat at the top of the chamber. Onthe commercial gaggias I worked on I used to take out the screen and hold it over the open flame of a stove burner and burn it clean rinse it with water to cool it. scrub it well and then put it back in the unit. Run a cycle with water only to check the flow and finish cleaning it out, let it get back up to temperature and then brew a cup and see how it does. Good Luck
I just bought a broken Carezza for my office (and hacking)-- the owner said the power switch only worked when he held it down hard.
Taking it apart, the main power switch-- a DPDT automotive-style unit-- is broken on one pole-- the wire connectors are slightly melted and darkened, and the switch has melted, discolored plastic around the metal tabs.
A new switch should bring it back to life, and I'll install a removable power cord and 15A fuse for niceness/safety-- the switch is rated for 20A at 125VAC so shouldn't have fried.
