Q. If someone realizes after saying the brocho for Chanuka candles that they will not light since there is too much water in the glass, what should he then do, just fix them and then recite another brocho?
A. Horav Shlomo Miller’s Shlit”a opinion is that he can lite the shamesh and ‘bediebed’ after the fact the brocho was not in vain. He should then add the proper other lights of the day without reciting a brocho.
