Saeco Aroma leak from steamer wand

Once machine is switched on, water dribbles or flows steadily from the steamer wand. Bought this a couple of years ago new. Reputable seller we think, (Whole Lotta Latte).

Simple valve fix? Or does this sound more pricey? Hoping to repair in our area (Colorado) rather than ship somewhere, but many repair centers handle only fancy commercial machines. Thanks so much and I'm thrilled to finally find some real help online re living with espresso machines.
