My ECM Giotto Premium is about 4 years old... turn it on, power light comes on, but it does not heat up and has a clicking sound that will not stop until I either turn it off or unplug. Not sure the tech at Espresso Parts in Olympia has it figured out yet... says it may be the 'Auto-fill controller'. Also says that ECM was sold, does very little business in the US of late and it's hard to find parts. He's supposed to take a closer look at it later today.... any suggestions as to what this could be and how to remedy it? Olywagal

Try this open the steam valve when you turn the machine on, leave the valve open until it starts to hiss with steam, then turn off valve. If that works then the vent valve is sticking and needs to be replaced.
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.
HI Make sure that the water level probes are touching the machine to ground themselves. Push down on the probes, and see if the machine comes on. With out looking at it I don't know what else to tell you.
Se my solution re no heat on page. pressostate or microswitch fail is easy to fix. many times the water tank is bebt out of shape with time. A twisted tank lift one side and tank is no longer resting on four points. This cause no contact with electrodes inside tank saying = no water = no power allowed. The GROUND must be established! A small piece of alu foil rolled to a ball will help to ground the electrode again. Lift the tank gently and find the two v - shaped contacts for the electrodes. Have also replaced the electronic box once :-( on friends ECM /// olev
My friend, had the same feeling,,,What have a done !! This piece of junk for all my dollars! No ,,it needs cleaning. Read all my comments re this. You can open this machine witha few fixed keys and mantain it. It will outlast you, when correctly mantained. All solid cupper and metal, no plastic. take it apart and CLEAN IT!
Remember - it is built by a human beeing. The ECM is a buty as it has very little automation built in. Very siple function = löong time in love with your machine. It is totally ANALOG = tweek it = better cogffee. /// Olev
Well, I just spoke with the repair tech where I originally purchased my Giotto Premium 4 years ago. He knew exactly what the problem was when I described it... power light on, clicking noise (not remedied by a hard boot), water not coming out of the grouphead, not heating up etc. Apparently, this is a common problem, but is not the heating element; it's the relay box costing about $200 from GCM in Italy.
