Which sleeve was broken? The one around the heater?
And for how long has it been like that?
(You are not worried about glass dust/pieces? Or that the glass suddenly collapses?)
Very strange that it switches on by itself (you mean it goes on without clicking it 3 times)?
You usually use it in on demand mode or in session? Sounds like it's somehow stuck in session mode (and maxed out)? Does the light stay on instead of blinking? White lights? PCB problem perhaps?
I agree with
@Pib that the behaviour you describe is pretty strange, i've read thru the whole thread (yeah, don't ask
) but i can't recall reading something similar like your issues.
Very curious what the diagnosis from the TM-people will be, sure hope they can fix it for you(i suppose they will).
Also hope that you'll update when you receive news from TM 'cause i really wonder what happened/what is wrong with it for it to act like it does.!
Good luck and hopefully you'll receive your backup device soon!
