Water leak on Denon Receiver - Advice please

[Deadbone]

Moderators, Please move this post if i have posted in the wrong forum.

I have sadly woken up to find my Denon AVR-2809 Receiver sitting in a pool of water. My air conditioner mounted on the wall above my receiver backed up overnight causing a build up of water to drip on my amp. Looks like about a half a cup of water has made it inside the receiver at the most. A couple of cups worth have landed around and near it.

On discovering this i have done the following:

• Receiver was not power up so i unplugged it.
• Unplugged all hdmi, speaker and power chords.
• Dried outside of receiver.
• Dried all input sockets and plugs on back face.
• Placed on towel under to absorb any water leaking from chasis.
• Opened outer casing to inspect amount of water inside.
• Small amount of water on back half of inner components and below. (very hard to see)
• No water damage on the front half's inner workings.
• No water damage on front lcd or face
• I am going to leave until dry for at least a fortnight until i try powering it up (Yes? / No?)

Anyone here had any similar tragedies?
Any advice on how to best deal with this accident would be greatly appreciated.

Read about using a hair dryer on low temperature (Yes? No?)

Don't think i will have any luck with insurance being the air-con.
Also going to check what my options are for accredited Denon repair person to look at it.

Thanks in advance

Take it apart and dry it out, don't let the water pool in there.

sorry to hear about ur misfortune...but I must confess...that is the most interesting Post Title I have read in a while.

And once you dried it out do it again and again and again for few days until you have made sure you absorbed any small water around the circuitry board otherwise it will short out and damage few components.

Leave it in warm room also and get rid of that sully air vent thingy!

As for condensation I found a nice TV CRT dumped many years ago around the winter time and took the stray home and opened it up and dried it and left it a few hours to dry on in the warm room and it worked when I turned it ON.

If I hadn’t bothered with it that night by around the next day it was raining cats and dogs and there would be no way I’d even bother with it, because it will go BANG even if I left it drying for month.


Word of advice never ever leave a device that is bound to possibly leak water over electrical items it’s dangerous! Don’t put cups or plant pots on electrical items or even speakers.

Water and electric does not mix!

That s*cks!!! Let it dry out, perhaps use a hair dryer to help. The fact that the water actually was able to "pool up", I don't like your odds of the receiver working in the long term. I don't really know of any true tested remedy for this kind of predicament......good luck!

Don’t use a hairdryer blowing hot or warm heat direct onto electrical components.

Use kitchen towels to absorb the water liquid and continue. Leave it to air out over a few days in a warm room. Use a good light to have a look around for any sly possible trickles of water hiding.

With a hairdryer you’ll only blow a few tickles of water elsewhere to make contact with other parts of the electrical components.

Good point..again, I never had to deal with this kind of problem or know of any resolution......so good luck OP.

Me nether have I. But if he uses the hairdryer that’s like blowing dust dirt elsewhere without sucking it up!

Wait a second! Maybe a small like vacuum tube like small fish tank pipe sucking the water up as you move it around while drying it at the same time with kitchen towels.

This may increase the time for it to dry because the wet dampness isn’t going to do the electrics inside any favours.

One I’d try not moving it around otherwise that water will move elsewhere and you’re really in trouble!

The internal fuse might have blow and hopeful protected the unit from any real major damage.

So remove the fuse its often located around the transfer power supply.

Its tiny little (glass fuse) remove and inspect it with good light to see if the line inside is broken. If unsure use a volt meter to see if the needle swings over.

If the fuse is intact then its possible the damage is worse. It will cost a silly amount to put right and you better have few $hundred saved up for the silly worst case bill!

Only tiny trickle of water that wouldn’t cost no more than few cents may have done hundreds of $dollars worth of damage, now then.

I gather this is the same AVR unit?

Yes, yes I see at least 4 fuses located near the transformer.
Remove and inspect them now!

Hold on I think I see two more fuses located right near the amplifiers heat sink. Remove and inspect them now!




Its also possible providing your you have nimble fingers to remove the back part of the PCB un-plug it from the rest of the PCB (while making written notes or pictures) so when replacing the parts back together in the same order.

This will show if you have water underneath but its tricky not to move it around otherwise if there is water underneath the back part there is no telling what part that water is making contact with?

But looking at those semiconductor chips if water got onto them while in standby this story looks bleak.

Also its possible that water had landed on the green part of the PCB then splashed and landed on the lower part of the PCB near to the amps and if that is the case, boy you have a lot of drying up to do.

Then again if its still under warranty send it in for repair.

Take some pictures of it as it is now! With the top of casing removed!

Something similar happened to me a few months ago when the heat pump condensation in the attic leaked into the hall closet I keep all my network gear in. Sorry for your misfortune.

Thanks everyone for the advice.
Also thank you JBL4645 for your very helpful and informative posts.
I was really freaking out when i posted the other night.

Yes, correct. Thats the model.

I followed your advice and left it in a warm room with the casing removed.
Seems like all the water has evaporated. Very hard to see.
May be some water still under the green circuit boards
(Back top right) and in front of that area. Seems dry though.

I feel a lot better about the whole situation today.
Apologies, it slipped my mind to take any photos.

I've actually re attached the outer casing because i have arranged to drop it off
at the hi-fi store where originally purchased it from. It will get it fully checked out by Denon.
Transport will be covered under warranty. It will be a different matter if there are any problems.
At least i will know where i'm at once it's inspected and tested.

Thanks again to everyone who posted.

Damn good show mate that’s the right move to make, get it in for fuller inspection. Should be back up and running two months given the work load they have that is an estimate time.
