I think your best plan is to put all your gear in room with a dehumidifer and leave it there for a few days. If thats not an option lots of silica gel in sealed plastic bags left in a warm room.  Using a hair dryer can just move the moisture somewhere else. If you can open the units up all the better.

Damp circuits can work but with current added it can corrode and oxidise so avoid turning it on. I have a lot of experiance with underwater camera systems and the old "classic" stuff  could usually be salvaged, so take your time.

Hi there I did Remove it all from the flat and into a small heated room. But My Beomater is playing up big time, or it could be my beolink 5000 not sure really, I think I need help from the one and only Dillen (Martin) After the flood the system seems to be getting worse! If you are listening Martin Could you please help me!!! Thanks Nidul

My first move would be to open the covers and put the components next to a dehumidifier.  There's a good chance they're salvagable.  Water is not the simple killer of electronics many fear it is.  Pure water is a relatively poor conductor, and the voltages found in the system typically aren't high enough to conduct through the water and cause a short.  The problem is that water from a water pipe (let alone anywhere else in your house) will be far from pure, and likely high in dissolved minerals.  The dissolved minerals act as a conductive pathway through the water.  Furthermore, when the circuit boards get wet, any dirt/debris/etc on the board can be pulled into solution and create a conductive pathway across the traces, creating a short.  Before turning anything on I would first make sure the internals are completely dry.  Then I'd use oil-free rubbing alcohol, or circuit board cleaner if you have it available, and gently scrubs the boards with that and a toothbrush.  Good luck.

P.S. definitely unplug and stop using the system for now though.  I noticed you said above you're still using it and it's getting worse.  When you have a small short starting to conduct between two traces on a board it has a snowballing effect.  That is, once you have enough minerals/salts in solution on the board to get a small amount of current flowing, that little bit of current draws more minerals/salts into the conduction path, thus lowering the resistance of the short and making the short worse.
