clicking sound on the low register -- Kawai RX3

Our one month old Kawai RX-3 just developed a clicking sound problem on the lower keys. A very cloud and clear click sound will produced after each key is released. The sound feels like a contact sound by wood parts. The sound is very annoying. I am going to call the dealer tomorrow, but just wondering if somebody with the knowledge can shed some light of the possible cause for this.

I'm not sure if your piano has an adjustable hammer rebound rail, but if so the stop nut is loose. Very simple fix. Or there is a foriegn object in the action cavity.

Thank you so much Dale. Glad to hear that it probably is just a minor and easy to fix problem. I know little about piano since this is the first acoustic piano I bought, so I do not know if it has an adjustable hammer rebound rail. The video in the link below was posted to demonstrate the click sound: http://video.yahoo.com/watch/7178491/18699485I wonder if I could fix the problem myself without waiting several days for a technician to come. I saw the technician inspecting a piano last time when I was shopping for a piano, and have figured out how to take the action out  . Thanks again...

That's something very easy and simple to fix. If you can do so, try removing the fallboard and you may find the cause of that noise right behind it.

The RX-3 does have a stop rail, and the nuts can work loose. You can actually get to some of them from between the strings with a flashlight and a standard screwdriver with a long, thin shaft.
If you look inside between the strings, near the hammer heads, you'll see the hammer shanks resting just above a green felt strip. That strip has 5 nuts holding it firmly in place. They can loosen up over time and are easily tightened.
But my recommendation is that you wait for the technician and schedule your free tuning at the same time.

Yes you might be able to, BUT,,,,,you may also break a couple of hammer shanks in the process. Among techs we always say that there are those who have broken hammer shanks when pulling grand actions.... and those that will break some one day.

I had the same click in the higher part of the piano and it was like the gentlemen said---a loose nut holding the hammer rest rail. Nice that it probably is an easy fix!

Thanks all the the help. The fall board on the Kawai is easy to lift, and there is no pencil found on the action. I will call the dealer to send a technician here. I think it must be the rebound rail as people pointed out. I will report back. (update)Following Dave Stahl's instruction, I found out it is the loosen stop rail. I can see the stop rail rocking after a key is hit. I fixed it using a screw driver in less than 2 minutes . Thanks a lot, Dave. This forum rocks!

Cinstance, That will be $125.00 please....  Funny how a small noise like that can be a real irritant. Glad you were able to make it go away!

Yeah, the same $125 that Dave just lost in a parking lot.  Now you'll be even Dave!
