Had it repaired worked for about 2 weeks then it wouldn't heat up. Espresso came out tepid. Turn the steam valve on, and pressure immediately plummeted. Then it started to work properly for about a week before the problem resurfaced. Today a new one - pumps cuts out when the lever is lifted to pour an espresso. Water just barely warm. In the shop the following had been done: pressure adjusted, replaced safety valve, liquid level probe and 2 gaskets.
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

First make sure that the nozzle is absolutely clean... If it is so, its most likely a problem with the mechanical steam valve spring. It could be that the spring is broken or even a pivot screw has come loose... You may need to open up the valve to check and clean
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.
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.
Ther is a very simle heating cirquit with a prssure swithch including a Cherry micro swithc. This thing is rated max 60C. With time the plastic just get bent out of shape and you have no pressure. have fixed by changing the Pressostate or just the Cherry switch. The Element must come on at low pressure. It has an mechanical setpoint. So hotter coffe (higher steam press) can be set with a scew driver. Finally the safety valve lifts and you have learnt a little re boilers. Leaking safety valve need a new seal, Be careful,,if not, your ECM will serve the first espresso on the moon/// Olev
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
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.

Have you checked the Thermostat on the unit in the tank if it is stuck it will cause the tank to over heat and pop off the steam valve?? there should be some resettable overheat protectors as well. Has the preassure relief valve been replaced as well??
