V Guard — submersible pump

I bought a v guard submersible pump on 2016. Now the pump is showing complaint (Elcb gets off while pump is switched on) after the warranty period.

I registered a complaint through vguard customer care and was informed that drona agency in pathanamthitta will attend the issue.

The agency told us that submersible pump after few years o[censored]se will show such complaint and suggested us to directly connect the pump without an elcb or else you have to buy a new elcb from vguard or abb.

My question is, i am using top brand elcb from l&t which i bought few months before, which i should replace with v guard or other elcb's. So what's the quality provided from vguard motors??

Really disappointed with the vguard service.
