Re: 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.

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.
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??
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.
sound like it need to taken apart for a good cleaning. Hard water will cause build up ..your user manual should tell you how. i have the manual. It says Hard water will cause that problem.here is the link for the manual.http://www.espressotec.com/store/pc/catalog/pdf1/ec1300_ecm_giotto_manual.pdf
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.
What you see is condensed stem comming out and no water. The pump is not sucking from the tank as ther is an air bubble in suction line. Still want coffe and don't want to clean your machine??? Flick up the lever with no group in place. Steam comes first then nothing. Pump is running and - voila - water comes as air bubble is gone. (Specially the first cup , never the following ones.) Now put back the group and brew your espresso. The machine is full of scale and neds total clean - by hand./// Olev
