Hello! Recently purchased Kawai ES-110. Wonderful sound. But 4 white keys are kinda hitting plastic body and make knock-noise. When I press piano body in front of knocking keys, they became silent. Example video is here https://www.youtube.com/watch?v=ez3gzYsqFGgAs my kids had cut piano package, seller refused to take piano back and had sent it to diagnostics. Service diagnosed piano and wrote that piano has no technical problems. Pretty fun cause it's not a technical problem. It's acoustical problem. ES-110 and Kawai digital pianos owners. Is that a defect or normal for Kawai pianos? See video above.

Hello aliaksej, When the piano was sent for diagnosis, did you describe the issue that you are experiencing? Generally speaking, if you are not satisfied with the level of support provided by the dealer/retailer, the next step would be to contact the distributor for further assistance. You do not state where you are based, however contact information for Kawai's international distributors can be found at the following page: https://www.kawai-global.com/distribution/I hope this helps. Kind regards, James x

Your youtube title is in Russian, are you in Russia? There are several users here from that part of the world who might be able to help you with getting service. I have played my friend's ES110 quite a bit and the keys are a bit on the noisy side. I can't say if they are more or less noisy than yours. It is surprising how noisy keys are on all digitals when the sound is turned off. Acoustic piano keys are also fairly noisy but you can't turn the sound off so you never really hear the key noise unless you play really soft, in which case they keys aren't so loud any more.

In our country (belarus) there's no official Kawai service. And seller chooses some unofficial ones. Yes, I described problem with more noisy keys. But I cannot be sure seller/service care about my problem and are interested to admit issue

If they turn out to be non-responsive, the good news is, it shouldn't be a difficult fix even if you had to do it yourself.
Likely what's happening is, as the key is coming up, somewhere in the action the plastic key stick is coming into contact with plastic rather than felt. So you'll have to shim somewhere with either a bit of soft tape/paper/ or felt.

No, it's not music rest related. Looks like I can live with that issue. Disassembly of an instrument under warranty can lead to warranty loss. Looks like for my typical usecases this noise is not critical and barely noticeable. So I decided to stop fight and start enjoying this wonderful instrument. Great thanks all!

Isn't this slightly self contradictory? If you're worried about losing the warranty, get it repaired under the warranty. Yes I've read your circumstances.

When playing piano on low keys, shots are really noticeable... So you're right, I need to fight for my rights and acoustical comfort.

I played my ES110 at mignight. Was pressing keys and contemplating on how great is that piano feel and sound and how sad it'd be to sell it away because of plastic body resonance. Hmmmm.... Resonance. It's an idea. Why it resonates? Maybe because of some assembly issues or piano construction? I've laid down on the floor and noticed that in the area of rear commutation block there's no additional screw and a distance between screw points is twice and half longer then between all others. So this is a constructional reason of resonance. And that's why the second ES110 in the shop was also louder in the same area. Of course, in the shop it ws not knocking as mine. Possibly, because it wasn't played for some time or hard? How do you think, is that possible to safely add/glue some noise suppressor inside the piano?

That's why we add wood to the higher-tier slabs - as keyboard action, bottom and top plate - and reinforce it with steel: it simply sounds better than plastic when combined with speaker drivers.
This comes at the cost of weight and the ES110 is intended to be a lightweight device. BTW: Be cautious with your slab, especially with turning it over instead of keeping it upright. My vintage ES100 occasionally loses oil (when being played at hot temperatures).
