Siemens Washing Machine — Drum issue so soon is shocking

Address:

Mumbai khar

Bought Siemens front load on 2015. Now since 2021 the machine is making loud noise getting unbearable. First we thought it’s overloading or some hook is stuck. But we found it comes every 4-5 days. Got it checked. Technician took visiting charges and said drum casting is broken. Replace entire drum and shocker for 15, 000 rupees or else machine will stop on its own. How can any machine casting break. We don’t even overload or over use it. Although the machine motor parts is under warranty still we are supposed to pay. What fishy thing is going on. I won’t buy Siemens again. Been an expensive experience. Please advice.
