We purchased Elica Burner from Punjabi Bagh, Delhi. We gifted to our son. in Bengaluru. He had problem with back pipe and got it changed privately as he was to start his Kitchen in new house.
He noced burners giving sound while working . He called Elica people who could not repair the defect and told him that it was a manufacturing defect and cannot be repaired.
when we visited him recently we found that it was risky to work with and some fire may break out suddenly.
I am attaching video of the working burners. If it is a manufacturing defect the burners my be repaired by grinding or changed for safe working.
