Further up the thread here I mention a friend with a Hobart professional under sink dishwasher unit in his home

Follow the clearances, supply the 240V 50 amp power, install a catch pan under it, soften the water if needed, etc. None of it rocket science if you are mechanically-minded, but requires to educate yourself and pay attention.

My friend is from a large family, and they had a proper commercial kitchen in their house growing up, so no big deal for him.
