Question about ECM Giotto Espresso Machine

2 Answers

Pressure and temperature go too high

My machine pressure overshoots to 2.5 bar or more. I took off the lid and unplugged and re-plugged all the push on connectors (cleaning contacts) this may have fixed the problem or it may have been a coincidence that the problem went away, but now it is back.

Anybody else have this problem and found a solution?

    I heard my Giotto making loud noises from the next room twice in the last week. The pressure was way up, around 2.5. I poured off some hot water and it came down but I am concerned what might have happened if I didn't hear it!

I replaced the pressurestat with a Sirai one which is supposed to be much more reliable than the original. That did it.

Hi just a tip from experience, grind the coffee fine and keep the spout ( where the coffee comes out) very near the cup, while making the coffee.

Air pressure excessive


that's a valve that's in line with the internal plumbing..that's all that restricts that pressure, which can build quite high.

can you provide the exact model number, please?

What causes water to leak from underneath the unit?


Most often the problem is that the rubber rings are too old. The best is to open the machine, put the lid back on top, add the water container, add water. Push the espresso button, and afterwards (when the espresso is finished) open quickly the lid and check the origin of the water. I have a magic de luxe and it turned out that when i replaced the boiler, one of the high pressure tubes were damaged. Other frequently occuring problems are related to old rubber rings. the cost virtually nothing, and are easy to replace!
Cheers,
Andre

The pressure is more the 2 bar in gauge and pressure safety valve is open when this pressure increse more the 2 Bar


Sounds like the the tube that connects to the pressure stat is blocked or the pressure stat is damaged and needs to be replaced.

Ok...I got heat. Hot water from wand. Steam from wand. Machine is cleaned 2 times a year with decalcifier. Screen cleaned every other month. Now...espresso come straight thru like there is no pressure...


The pressure is from zero to the opening pressure of the OPV. This should be about 10 bar when the OPV is cold. When the OPV is hot, the OPV spring is hot and a little more flexible. The OPV opens at about 8.5 bar when hot.

When the wand valve is open, you can get a lot of steam or water with not a lot of pressure in the boiler.

Take the lid off the reservoir and watch the hose from the OPV. It's the short hose.
Pull a shot with less than usual coffee in the basket.
If you see water flowing from the hose, the OPV opened.
If it did not open and there is little extract in your cup, buy a new pump.

Steam wands on espresso machine wont work


There should be a boiler pressure and water pressure guage. If there is no pressure on the boiler guage that could mean a heating element or pressure stat problem.

I recently bought an Avanti Art Deco 10 cup espresso machine and am disappointed that I cannot make HOT coffee with it. What can you suggest?


When the water boils in the bottom chamber the steam creates pressure and pushes the water through the grounds and into the top chamber. It's hard to imagine that the water going through the grounds is not close to boiling temperature unless you are using the coffee maker at high altitude where the temperature of boiling water would be lower.
