What does dishwater mean?
Dishwater is the water left over after washing dishes, plates, and cooking utensils — typically cloudy, soapy, and greasy once the washing is done. It is almost always treated as an uncountable noun, and its everyday home is the kitchen sink, where it is simply poured away. Beyond the literal sense, however, dishwater has developed a vivid figurative life: because the liquid itself is weak and flavorless, English speakers use it to describe any drink or food that tastes watery and bland — coffee or tea dismissed as tasting "like dishwater" is a familiar complaint. The word also appears in fixed idioms such as "as weak as dishwater," applied to feeble drinks, feeble arguments, or even feeble personalities, and in the informal expression "dishwater blonde," describing dull, washed-out blond hair. Negative in tone and informal in register, dishwater is a small but expressive piece of everyday vocabulary.

"Weak as dishwater" has been an insult for bland drinks and bland personalities alike for centuries — and a "dishwater blonde" is hair so dull it's compared to the sink.

Etymology of dishwater
Dishwater is a straightforward English compound of "dish" and "water," formed within Middle English when such household compounds were common. The element "dish" traces back through Old English "disc" to Latin "discus," meaning a plate or quoit, which also gives us "disk," "desk," and "dais." The compound has been part of the language for many centuries, and its figurative use for weak, insipid liquids arose naturally from the unappealing nature of the literal substance.
How dishwater is actually used
Almost always used as an uncountable noun; a plural form would only appear in unusual or humorous contexts. The word carries a strongly negative connotation in its figurative sense, implying weakness, dullness, or unpleasantness, and appears chiefly in informal speech and writing.
