Reply To: Relying on a heter of someone else

I think the subject of thread is wrong. If your Rav told you that you can Kasher it easily, that is not a hetter. That is a psak that you can kasher your dishwasher and make it 100% kosher as far as he is concerned. If other Rabbonim pasken that it can not be kashered, then that is not a chumra, but a psak that the dishwasher can not be kashered at all and it remains treif (unless they hold that me-ikkar hadin it can be kashered but they want to be machmir like a specific shita for whatever reason in which case, the first Rav is not maikel, the second is machmir). In which case your quesiton becomes, if I have an item that is kosher meikkar hadin, but someone is noheig a chumra, am I obligated to let him know that he would be violating his chumra, or conversely, must he always investigate that all situations conform to his chumra. To me, the word hetter always comes with the implication that the Rav found a loophole, which is often not the case and where possible, I try to avoid its usage because it is disparaging.
