My 3 year old thought the LCD display is a bowl and poured water in it.
It's Yamaha DGX-500 where the LCD is recessed in and kid thought it'd hold water. This kid has some imagination.
Not a whole lot but when I tilted it, I saw some water came out from the keys.

Thankfully, it was not plugged in.

It's been 3 days and unplugged to let it dry completely.
I don't see any water from outside and when tilting/flipping it but I'm still afraid to plug it in.

It's not a phone to put inside rice and I don't have that much rice anyways.

Anyone had similar experience?

Lateral thinking! Will do well in future life!

Can you get a trade-in on the piano? Or, better yet, can you get a trade-in on the kid?

But seriously ... if you allow the piano to dry out thoroughly it's quite likely that all will be well. How can you know the water is dried out? If water has seeped inside you could open up the unit to see. It's a chore, but that'll give the answer.

Or you could wait for mother nature to take over. If there's no evidence of pooled water ... give it a week to dry out. Then give it a try.

There's little danger from line voltage. The circuitry around the LCD is low voltage only.

As per Mac I would either open it or wait a few days if it’s left in a dry warm place. Sometimes even dried out water can leave a trail that long term can cause problems. Sometimes not. Which is why I would open it up at some stage.

Pouring a pint of beer on a 60's transistorised organ caused to to go wildly out of tune. But it dried out out rapidly and normal service was resumed. No further troubles.
I therefore conclude that water will not harm it.
There is, however, the piece of MDF which may form the base of the instrument. Shouldn't harm just once.

Thanks for replies.
I'll let it dry until this weekend. Hopefully, it'll work.
Colorado is very dry so that helps.


Haha... hopefully.
He's very creative and curious.
He has dismantled (not broken nor thrown) many cars and other things to see what's inside.
When he gets legos, he'll be on his own for long time making different things.
My older one never had that much patience.


No trading the kid. I started family late so can't risk anything.
I have another keyboard, Yamaha P-70, so no need to get another immediately.
Oh, also have a Casio WK-200 so non-weighted, semi-weighted and weighted all 3 types of keys.

What to expect? Jail time for child abuse? Lol... Also one hurtin kid with no allowance for a WHILE? lol....

Generally nothing should happen. Once you dry it all the piano should not know it was washed.
Although the DGX had the unfortunate issue with the display contacts and the water may not help I am afraid. If your display goes like half black etc don't be mad at the kid - it was going to happen soon or later, the water only helped speed it up... There are replacement displays because it is well known issue.

Perhaps try this: spread a lot of uncooked rice in a large pan. Wrap the pan and the whole piano with plastic sheeting, sealing very tightly and allowing air access tom the pan of rice. Wait three or four days. If necessary, repeat.

The rice will absorb quite a bit of water.

I'd open up the keyboard and either use a hair dryer or simply a fan to let it dry completely out.

Fortunately, your keyboard seems to run low voltage from a wall power supply. If you shut down the machine & clean fast enough there may be no damage.

Water has a way of quickly destroying electronics so you need to take care of this ASAP. Keyboard may or may not play fine in a few days but damage may continue for a while and the unit will die in a few days, weeks or months.

iFixit has some detailed preliminary steps for water ingress to consumer electronics. There are a lot of comments at the bottom of the page for additional information. This is a good place to begin your research.

When my family spills liquids on electronics, we follow a few simple steps. There are better procedures and more steps so you can consider this preliminary research. You could send it to a professional electronics shop for a professional cleaning if you are uncomfortable:

- Power down / remove power cord & batteries immediately.

*** Use extreme caution for health and safety, especially with components that run at say 120-240 volts. For example, power cords must be removed, all caps properly discharged but that is not all. Modern batteries in mobile phones, laptops, etc. can be extremely dangerous if punctured, shorted or failed. Consumer electronics can kill you and/or burn down your house.

- Open unit and blot water with paper towel (wear gloves as unknown chemicals inside electronics can be dangerous).

- Look for visual damage around soldier joints, PCB, components.

- Gently scrub PCB and most components with 99%+ alcohol using a lint-free swab or clean soft brush (lower than say 99% household alcohol has impurities that you are trying to remove but somewhat less pure alcohol might be OK). Make sure room is extremely well ventilated and wear protective gloves and glasses.

==> You need to use judgement with the disassembly as you don't want to break the keyboard. And you probably don't want to be immersing the LCD screen in alcohol (albeit you may clean the electronic contacts). And you probably don't want the alcohol to contact the keys, some rubber bits, greased joints, etc. The alcohol is principally to clean soldier joints and the PCB.

- Reinspect. You may see some soldier joints that have become crusty; these need to be clean and neat so may need to be cleaned up and re-soldiered. A tech can run some quick tests with a multimeter but that is beyond the scope of this comment.

- Blow a fan on the unit for a while in a warm dry room to help dry the unit. . .Reassemble

Don't use a hairdryer around the boards inside the unit. You can end up having an electrostatic discharge (ESD) which could kill the whole thing. Just because you don't see or feel the charge, doesn't mean it didn't happen. This is the same reason you should not use electric blowers or vacuums around PCs.

I'd let it just dry out on its own. Open it up if you have to, but nix the hairdryer. Electronics can work without issue after being submerged in water. The issue comes when electricity is flowing through the boards and there is still water in the unit which conducts a charge and short circuits the board.

I plugged it back in last weekend and so far working fine.
The display is working as well.
Hopefully, he won't do it again.
Here's the victim:

Be glad that it was water and not Coke.
