According to the equivalent thread on Team-BHP, their washing machines were rated highly when they had a partnership with Bosch. However, they are not now, and nor is their customer service.
No personal experience, just passing this on, but, on the basis of what I hear I would not buy IFB.
It is true,their washing machines from the past years( after their termination with bosch)have really poor build quality.They by far had the worst fit and finish compared to any other brand including haier .
Another thing negative is the after sales support.
Those who want good washing machines with the best build quality stick with bosch,Siemens both are eurpean and whirlpool a american company which is the worlds largest home appliance maker.
Lg is gaining popularity thanks to their good after sales support and cheaper price.They are definitely much better then current IFB.
