Phone used in swimming pool for less than a minute, now totally dead.

Question

Hi there,
One of the features which made me buy the Z3 was its apparent waterproofness. However, the first time I put the phone under water (in a swimming pool) was also the last - and the last time I've been able to use the phone.
I only took a few shots and the phone was submerged for probably no more than 30 seconds total. I checked all the flaps to ensure it was sealed before putting it under but almost immediately the screen started to fade and the phone became almost totally unresponsive. To turn the screen on I had to press the shutter button as the main one did nothing. I rinsed it under tap water and left it to dry but after coming back to it the phone (or screen at least) was dead. 
Two days later the phone started making some noises (like low battery, but more erratic over a few minutes) but it's still totally dead. A red LED comes on if you put in a power cable and holding the volume and power button together for a few seconds leads to 3 rapid vibrations but still nothing.
What's the process for getting Sony to check this out and (I hope) repair or replace the phone? I'm in Ireland.
I've had the phone a couple of months and it's been great up to now. It seems this is a common problem and the average response from Sony seems pretty depressing.
