No.
Many manufacturers use different methods to mount their LEDs and these can all have unique issues. For instance, I was recently given an EQD Hoof to repair where the LED was intermittently going on and off. The way it was mounted meant that it was easy to push the LED back, which led to the leads shorting against the PCB. I simply pushed the LED fully home into its bezel and hot-glued it in place.
I have also encountered LEDs where the electrodes aren't completely encapsulated within the body of the LED which means they are free to short against the enclosure if mounted directly. Not one of my easiest troubleshooting sessions, I have to say.
We will be able to get to the bottom of this, but the more info you can give us, the better.

It's a Dwarfcraft built DeviEver BDSM. The LED is 5mm clear/white which glows purple.
I have removed it, cleaned the board where it connects and re-attached it with leaded solder.
I'll take some pics later and if I have time I'll check that there's still 9v going to it when it dies.

The red circle is where the LED connects. I put my multimeter on it while it was plugged in and got 9.83V from the power supply, 7.25V between the 9v in on the board and the hot side of the LED and 2.5V across the LED legs.
There's continuity between the LED hot and the power supply, and between the LED ground and the board spot marked LED (and the switch).
As happens every time, it works perfectly well for a minute or so and then starts to lose some brilliance before going very dim or cutting out completely.
I tried gently pressing the LED and wiggling it about while it was not working (but switched on) to no effect.
Once it's just about failed completely it does flicker on now and again, but nothing I did physically made this happen.
Update: I found some LEDs in a drawer which I knew worked and swapped one for the one in the pedal - success!
It's blue instead of purple, but it's no longer cutting in and out
I've got it sitting lower in the case so there's little chance of it receiving a blow, so hopefully that's that, for now at least.
You mentioned that you replaced the LED with another at some point. Is it possible that you inadvertently got it the wrong way round or overheated it? LEDs are surprisingly prone to heat damage.
