My IFB stopped working exactly after a year! chip got busted and the door knob too. Called service for around a month and they didn’t turn up!
They are so very arrogant, and like a computer will repeat "we will fix it by tomorrow" and nothing will happen! Waste of money!
Now I am going for a second m/c. In all my life never have replaced a appliance in a year. Avoid it REALLY LIKE A DISEASE! and save yourself some heart ache.
