Hamilton Beach Coffee Brewmaster- coffee tastes like PLASTIC

We got one of these Brewmasters and we really love it. The idea that you dont have to fool around with a glass carafe is nice. However, we have noticed that the coffee seems to taste plasticky..when the coffee brews, it sits in a plastic bucket until its dispensed. I do not know if thats the reason coffee tastes funny, or if it picks up the plastic taste from the container the water is poured in to...we use bagged coffee, so its not picking up taste from a plastic can...we are just so disappointed with this, as the coffee maker is really cool. We do keep our coffeemaker clean and our water is not hard. Has anyone else had this issue?

thanks, Ken
