Re: This Does Not Necessarily:
Have a Porcelain Tub, my Brother and Sister-In-Law have that very same Washer and theirs has a Plastic Tub. It is still going strong however, with only a minor Repair Call needed, being "Operator Error" of my Sister-In-Law. She forgot to turn the Water Level Switch over to the Reset, before changing the Water Level and didn't know why the Tub didn't fill up to the Higher Level Setting.
It is also after the Burpalator Agitator and Filter Assemblies, it has the "so-called" Self-Clean Lint Filter System.
Peace and Good Laundry Times, Steve
