hiya john... yeah, i see the screw and cover (with Therm on the top,
silly me) , but its tiny, and i dont know what will fit around it to
remove it...

I have just unscrewed it, but there is no immersion stat underneath,
so I dont know whats going on..

There is usually a little pointer type device there to set the temp. It
may be you have a fixed temp immersion, in which case one would expect
it to be high enough.
