We’ve had three induction hobs, one Hotpoint and two Samsung, two of them died within a couple of years, the latest samsung seems okay but I’ve never experienced the pulsing thing with any of the hobs going back to 2011 when the Hotpoint one was first installed however we do get pulsing when the pot doesn’t connect to the hob ring properly, usually that happens with a Moka pot which is tiny relative to the smallest hob ring.
Might be your pots that’s the issue OP.
