Samsung Dishwasher DW-FN320T
Talking about Dishwasher -> I would expect it to be rust proof since it has to deal with water.
I am putting up in central Delhi and the TDS of water is around 100-120(Excellent to drink as is). So, I can not blame water for this.
Samsung need to work on the products quality.
I called up Samsung support within warranty period and they denied for replacement of rusting parts instead were asking for hefty money.
Thing twice before you purchase Samsung Dishwasher DW-FN320T. Big No No for me.
