Question about ECM Giotto Espresso Machine

2 Answers

ECM Giotto Occaisionally the pressure will build beyond beyond one bar.  It is intermittent, and when it happens the machine will make hissing noises and then the pressure can build beyond 2.  Today it went above 2 and created a lot of steam all on its own before I realized it and shut it off. After it is shut off and then I turn it on again, it generally only goes to 1 bar again and is fine for a couple of days.

    what is the pressurestat? is that the same as the safety relief valve?

    I saw some posts on coffeegeek (that I found from your link) that talked about a problem that sounds like mine - they said that the pressurestat goes out and the machine builds in pressure intermittently.

    The hissing noice you mention is the vacuum breaker valve. First try to clean it and if the problem continues then it might mean that the vacuum breaker valve is broken, or you need to replace it.

    Try to do a quick cleaning by pouring some water with a bit of washing dishes deergent.
    If you mention your pressure gets a bit out of contorl then the hissing noice can also be the safety relieve valve (over pressure protection).

    Hi again,
    It can either be the safety relief valve, or the vacuum breaker valve.
    I cant tell you exaclty witch one it the one making the hissing sound by internet, so you will have to open it and carefully look at it and see wich of those two is making the noice.
    This is another link that i conisder very important to solve the problem you are having

I turn the ECM Giotto on, the light comes on but the pump does not activate and no heat. 2 hours later it all works fine.


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.

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?

The hising is your vacuum breaker not closing. Check you heating element with an ohms meter. It should read between 14 and 17 ohms. If you get a larger or no reading its your element. It needs to be replaced.

My 5 year old Giotto has stopped working


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.

Hey! My ECM Giotto is building up too much pressure. 2+ bars. I tried resetting it but no lick. New thermostat?


The pressostat can be full of scale. You can remove it when the machine is cold descale it and also use a litle lubricate so the part can move more easily. You migh need a new mebrane since it might have be damage but if you dong have you can cut a plastic the same round shape of the mebrane and put the both back again so that no steam will escape from the mabrane.

No Pressure..No heat


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

Giotto pressure valve constantly on


You must have an internal leak and your machine will need to be serviced. If you can remove the top of the machine maybe you can see where the leak is coming from and may be able to repair the machine yourself.

Air pressure problem


Hi,

 

I am having a similar problem.  Doesn't happen all the time, just sometimes.  My research has led me to believe it might be the vacuum breaker valve.  I am going to order a new one here:

I'll replace mine & post if it fixes it.

 

Good Luck
