I was cleaning my Rancillo Silvia using the blind diaphragm doing the 5 seconds on 10 off cycle and noticed that when I turned the brew switch off water released into the discharge drawer from the covering behind the brew basket steam wand etc. When using the blind diaphragm there was quite a bit of water. If I removed he diaphragm the water reduced to several drops. is this normal. My machine is 3 months old, This is the first time I noticed this as I had the drip tray removed.
