IFB Industries — Washing Machine Issue

Address:

Kanpur

I have a IFB washing machine 8 kg front load fully automatic, purchased in 2019. In October 2023 they changed drum of machine costing 7000/- Rs. And now on January 2024 it's PCB got burnt. Cannot understand how whole PCB got damaged, as every electronic machine has its own fuse, which gets blown out in case of surge. And it's only job is to protect costly part of PCB elements from damage by getting blown out. But see the case of IFB waching machine, it's Fuse is pretty safe and rest of PCB got damaged. And now they are charging RS 6800/- for PCB replacement. I need to ask technical team IFB why do you put fuse then what is its use, if it can not protect PCB.
