Bosch Home India — Washing Machine Power Module Failure

Address:

Delhi

I am aligned with the complaints here.
I have a 15yr old IFB (which also used Bosch components) but never failed in all these years.
I have a Power Module failure on my washing machine WAT28469IN - Bosch 8kg front load which i purchased in 2018/19 but it is as good as new (because for 36 months we didn't use the machine at all).
I come home after 3 years and turn on the machine and it's dead and Bosch confirm it's a dead power module (i.e. the main PCB that sits at the bottom left at the back of the machine).
@Bosch India: This is unfair that a machine costing 52, 000/- has such an expensive part replacement - Bosch quoted 15, 000/-
Kindly give me a reasonable quote or else I'll be forced to repair the PCB (thankfully I'm an electrical engineer).
