[Resolved]  IFB — washing machines ifb

I use an ifb fully automatic top load washing machine. One day my machine was not starting so i called the ifb technician. He inspected the machine and told me that the motherboard of the machine is damaged and cannot be repaired. I was surprised to know the price of the motherboard rs 5500.
I asked him that how was it damaged. He told that water had gone into it through the knob (Program selector).
I want to tell ifb that at the time of purchasing the machine the technicians visit us and told us how to use the machine and features of the machine. But he didn't tell us that water can get into the motherboard through the knob.
I think ifb doesn't know that this is a important thing that consumers should know.
I think ifb purposefully doesn't inform the customer about these problems so that they can earn through the sale of the spare parts.
