Question about ECM Giotto Espresso Machine

3 Answers

Pressure on my machine builds up rapidly, when I open the steam valve, the pressure drops to zero and the machine begins the heating cycle again. It takes several rounds of steam bleeding to get the unit up to operating temp. then it works fine.

    I live in an area that has virtually no minerals in the water. I have even been advised to not descale the machine as there will be no scale.

    I found another resource that pointed me to a small probe on top of the boiler. It regulates the boiler fill. I removed the probe and cleaned it with Scotchbrite, replaced the probe and followed your boiler fill recommendations and I think it is cured. I will know for sure tomorrow AM. Thanks for the help

    The experts pointed me in the right direction. with a little digging and experimenting on my part the problem was corrected.

Sounds like the boiler tank isn't full.
Try
filling the reservoir,
open the steam valve and turn on the coffee espresso pump at the same time. This should pull water thru the system and then you can shut off and shut the valve to the steam.
Then let the machine cycle up to operation temp.

    I forgot to add, after you run the pump and steam valve to prime with water, be sure to refill the tank.

Hi, 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 might need a new mebrane since it might have be damage but if you don't 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.
Thanks and take care

First time user, steam valve on my xl power pressure cooker sits loosely in the sealed position. Wonder if it is broken. It doesn't turn easily to open. haven't started cooking yet. Can you help me?


the valve is a safety valve to release pressure that gets too high
the action is by the weight of the valve itself sitting over a small opening
as pressure is generated by resistance to flow, that small opening area has to have enough pressure ( psi /surface area) to overcome the resistance to flow ( the weight of the valve body)
when that happens there is a brief loss of pressure and then the valve reseats and the cycle begins again
simple ,effective and safe
to relieve the pressure before opening the lid , remove the valve

Seems to be a problem with either the elctronics sensors, or the "brain" itself. Did you get the machine serviced by an authorised service center, or a local repair guy?

No steam pressure


Leave the valve open until it starts slowly hissing, then shut off valve and wait for the pressure to build up.

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.

When water enters fridge for ice maker, it makes banging sounds. I have replaced valve several times, but still gets banging sound after a short time of use


The banging sound more than likely is being caused by your water line that is attached to the rear of your unit banging agains the chassis or wall. It can also be the line inside the bottomg of you unit striking something. This banging most likely is caused by what is called a watter hammer. When the ice maker cycles and the water valve opens momentariily the pressure in the line drops and when the vavle closes post add water cycle the pressure rapidly builds up in the line causing the line to move and strike something. Over time this can cause a water leak from the water line chafffing and the line begins to leak. It is not a serious situation but I would keep an eye on the copper or plastic water line to see what it is doing during the add water / fill cycle of the ice maker.

How do i use the pressure cooker? After adding water and beans, I let it come to boil and the steam noise is steady....then I turn down the heat? At the end I let out the steam manually, turn off and open...


Add the water and beans. Put the lid on the cooker and tighten down. Turn on the heat and let the steam make a full plume before closing the valve. Lower the temperature to medium. Watch the gauge and when it reaches the correct pressure keep adjusting the heat to maintain the pressure for however many minutes the beans need to cook. When the time is up turn off the heat and let the cooker cool for a while. Ten minutes or so. Then slowly open the pressure valve when the pressure has reduced to a low level. If the pressure is still to high when you open the valve the water will be pulled out of the beans and the jars will only be half full of liquid. Once the pressure is down to zero, open the lid carefully because the jars are still hot and break easily. As the jars cool you will hear them pop. This means that they are sealed. Good luck.

Pasquini. Livia 90 intermittently building up too much pressure


The part that will solve your problem is an upgraded heating rewire kit which will control pressure electronically, not manually. The rewire kit is Part #90000, $28

You may also need a new micro switch which is connected to your PStat with the rewire kit. The micro switch part #7633905, $13

These parts are in stock. I can send you these parts and instructions to install these parts in your machine.

My experience is working over 10 years at Pasquini as a master technician running the home repair sales and service center.

Old 1996 nuova simonelli mac digit no pressure or heat


There is a reset thermostat on the right side of the machine above the element, check to see if it tripped. If it did make sure there is enough water in the machine and when turning it on, open one of the steam valves and turn off the cup warmer. Leave the steam wand open until it hisses or small amounts of steam or air will vent out.

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
