For those that replied and for anyone else for that matter :)
The problem with my K3 not turning off was a faulty KIO3 board (Pt#
E850235), the one with the Acc. and RS232 connectors. Elecraft sent a
replacement board and this resolved it.
I will post a description of the problem, steps taken to isolate it to
the KIO3 board and possible solution (wash it!) to the Wiki asap.

My K3 appears to have developed a power switch problem - it won't turn
off.
After investigation, I found that pressing the power
button results in one of the following behaviours:
Most common: LCD just shows background colour (light is on), LEDs are
off, effectively the rig is off (no AF etc), but the LCD is not and I
can't turn it back on with a press of the power button.
Occasionally: K3 turns off correctly, but then turns back within a
matter of seconds.
Less occasionally: as above, but turns back on after a few minutes.
Rarely: Appears to turn off as per first scenario, but LCD flickers.
To resolve this, I have to pull out the power cord and plug it back
in, in which case the K3 turns on - so it's like the power switch is
permanently on.
