Appliance Repair Questions? Ask a Technician for Answers ASAP
Hi my name is ***** ***** I will assist you this afternoon.
I havent come across a Myra power shower, but do know of a brand called Mira.
To better answer your question can you supply a photo of what your look at, or failing that explain what you are referring to with regard to the 'plastic fitting', is this the trim which sits within the temperature control knob housing?
Once I can see what your look at I can better assist you with how to remove the outer case.
