sounds like you need to calm down and have a cold shower.....
oh VERY FUNNY !!!
ANYWAY: I have found a utube thingy of a similar unit [back off] showing how to do simple ohms/continuity tests* on the main components; that may well diagnose a part (e.g. heating filament(s) ), and some SHOULD be available from the Mira site linked above [thanks!].
There is hope ... of a better shower in my future :P
*it will probably take me longer to get it off the wall than to do the tests ... Does a real man bother taking out fuses for such tasks?
