New Kawai K3 sound problems

[ainmpiano]

I am a beginner with a new Kawai K-3  (3 months new).

How much "quality" should I expect from this piano?

I ask because in the weeks since I bought it (it was tuned before they sold it to me) some of the keys have lost their proper sound.

The E and F above middle C have a sharp metallic ringing (what I am told are overtones) that the other keys do not. 

I have excellent hearing, so this is really noticeable to me.

The piano is on an inside wall, away from windows and vents, and I have the humidity at 45, what kawai recommends.

The seller (a reputable local store) has told me to be patient, and that the overtones may eventually go away with playing. They are not refusing outright to send someone to fix it.

Should I demand that they send out a tuner to fix this...or should I call the Kawai company...or should I wait 6 months?

Thanks.

If it was last tuned before it was sold to you (ie, it has been moved since) I'm surprised it's just a few notes.  New pianos normally get tuned a bit after purchase, then again after three months then again after 6 after which they should stay in tune 9-12 months between retunes.

Yours is due for a tune. At this point, that's normal.

The dealer refused to do a full tuning gratis after I bought it, although I thought that was standard.

I guess I have to pay a tuner now.

Or shouldn't the dealer really take care of this?
