I received this machine about 5 days ago.  So far it's been easy enough to use but the water that comes through the espresso maker and frother has an extremely strong plastic taste.    When steaming milk the plastic taste transfers to the milk.  The plastic odor and taste has made every attempt at a bevarage undrinkable. 
We have a whole house water filter and I make coffee with water that's been through my fridge's filter too so the problem is not our water.  
I washed the components before first use and have rewashed the resevoir several times.  I don't know what else to do, probably returning it.
