Hi All. My Giotto ( non premium ) is hissing from what looks like some kind of pressure relief valve on the top of the machine, just under the holes in the top cover.
It waits till it gets hot, then the hissing starts and goes for about 10 seconds, then stops for about 10s, , then starts again.
Im thinking this is a faulty valve or something ? Any ideas ?
thanks in advance.
