I purchased IFB model NRW10 which is a commercial model for my resort, from the day it was purchased it never functioned a week without a problem and the technical team IFB sends has no idea of the machine working.
This is when we are located in Goa and it is here they have their HO. I saw lot of customer facing same problem with IFB in India and would advice anyone going in for IFB products to consider them as use and throw equipment as after sales service for IFB s**ks, even by Indian standards.
