Enough to break the dishwater and the fridge.

那次满潮足以损坏洗碗机和冰箱。

I'm impersonating my dull as dishwater doppelganger, Elena. She has the worst taste.

我要假扮我那无趣透顶的二重身，埃琳娜。她品位奇差无比。

Weak as dishwater or dull as ditchwater.

弱如洗碗水或沉闷如沟水。

To my mind this makes more sense: " Weak as dishwater" because dishwater is when you're cleaning your plates, when you're washing up, it's that water that's left, slightly grey, dirty-looking kind of water, that's what you get left.

在我看来，这更有意义：“像洗碗水一样弱” ，因为洗碗水是当你清洁盘子时， 当你洗碗时，剩下的水，略带灰色，看起来很脏的水， 这就是你的意思离开。
