After about three hours of negotiations with a technical manager Mr.Raghupathy, who reiterated that the technician didnt offer to change the PCB for free, but only tried to change it for a lesser cost of Rs.5000 instead of Rs.6000, I have decided to junk my 4 years 6 months old washing machine "IFB Senorita Aqua SX", and buy a good old durable Samsung washing machine.
Its a wake up call for me, after losing Rs.32000 on a IFB product that doesnt even last for a full 5 years.
