I bought an electric drip coffee brewer, and have found that it imbues the water passed through it with a plasticy taste and smell. (Unfortunately discovered this after throwing the receipt out.)

I've tried just boiling water through it several times, but it hasn't had any noticeable effect.

Can anything be done about it, or am I better off cutting my losses and buying a better one?

UPDATE: Tried running vinegar through it, and it seemed to reduce the issue, but not eliminate it altogether. I might try it again and if that doesn't do the trick, time for a better coffee maker.
