I had bought a IFB senorita model for my mum about 2 years ago, simple electro-mechanical control switch with no electronic display or circuitry.
It is still working with absolutely no issues, since Kochi is famous for electronics getting worn out.
Try to look for a simple machine with not too many gizmos, so that the machine lasts longer in tough Indian conditions and is easier to service.
One thing to remember is that Washing machines handle three things - Water, Electricity and soap together.
