My ECM Giotto is 3 years old and recently started leakin. I called the place where I bought it and they suggested it might need new gaskets around the group. I received them but have no idea how to remove the old one which has become very hard. I am not mechanical and do not want to do any damage. Please help.
I tend to remove the screw holding the shower plate to the group.
Take off the shower plate, and the metal diffuser (a round heavy metal piece) should come off with it.Sometimes this needs a little encouragement with a screwdriver..:)
Take a long thin screwdriver, and place it on the old gasket in the group.A few taps with a hammer (TAPS, not hard), and the old gasket should break.You should be able to prise out the gasket now, but it may take some moving if its been there a while.
Give the group gasket area a clean, i like wire wool for this.
Put your new gasket in the group and press upwards until it slots in.Some take more pressing than others.
Try the handle in the group to make sure everythings ok.
If the handle does not fit, the gasket is not in correctly.
Then replace the diffuser and shower plate and test.
Hope this helps..:)

i had this happen myself a few months ago, power switch blew, i took the machine apart took out the power switch, and visited a few local electrical component suppliers, its a standard switch but its 2 stage single throw switch, home depot/Lowe's don't carry this type. ended up going to 3 diff suppliers and finally found a commercial supplier that had it connected the new one and now its fine, works better than the old one ever did. just make sure you bring the broken switch with you when you go to show them, most good suppliers can match it and see if they have one like it in stock.
Did you find a solution yet? If your machine isn't plumbed in, so you have to fill the reservoir, I find it is easy to overfill, and the water runs out over the lip. I placed a fishing float with the long bit sticking up through the hole, so I can see when the water level is too low.
The vent valve on the machine is stuck in the open position. Turn on the machine and open the steam wand until you hear a hiss or see small water bubbles from nozzle, let it steam out a little more then close wand, that should allow the machine to heat up correctly, then order a new vent valve for the machine.
Check the shower screen and diffuser in the head, they might be blocked, if not, check the metering jet at the top of the head(large nut) CAREFUL, make sure machine is off and cool before removing, use a paperclip or pipe cleaner to clear blockage. If not blocked then you will have to check the brew solenoid.
How old is the coffee being used? Normally if you change baskets, the grind should be the same, because the single basket has finer and less holes in it than the double basket. The only difference would be the tamp then, since the coffee grinds works great with the double basket. You would also have to use a different volume of water to produce the coffee. To produce 2 ounces of espresso you need about 3 ozs of water,(about an ounces of water will remain in the coffee).
I am assuming that you have basket style shower which sits in the gasket and then inserts in the group. Find the small bevel edge on the gasket, make sure that side is facing up, place gasket on table then insert shower in gasket, then lift gasket, until it sits at the top of the shower(use a small flat screwdriver or a small hard brush to clean the group where the gaskets seats), then insert gasket and shower in group. Push in as far as you can then use the portafilter to seat the gasket in all the way.
If your shower is the flat style then there should be a hole in the middle for a screw.
Jonny boy,,If you ever had a Macano box as a kid, tthe best man to fix the machine is you! Take many photos before opening the pipework. Clean out the scale and learn about your machine! No kidding, you brew a better coffee after that. You know ALL the functions after looking into the machine + ther are some ways to tweek it too. Steam press cam be set as well as water amount. I brwe a better espesso tha I get on town. Thick light brown crema. I gave upo with the dealer and hes so called repair people /// Olev
What you see is condensed stem comming out and no water. The pump is not sucking from the tank as ther is an air bubble in suction line. Still want coffe and don't want to clean your machine??? Flick up the lever with no group in place. Steam comes first then nothing. Pump is running and - voila - water comes as air bubble is gone. (Specially the first cup , never the following ones.) Now put back the group and brew your espresso. The machine is full of scale and neds total clean - by hand./// Olev
