Plates or glasses under falling water, indicating dishwasher use.
Also known as: Dishwasher symbol, Dishwasher proof symbol, Plates and water symbol
Dishes with water falling on them mark an item as dishwasher-safe. Like the microwave mark it is unstandardised, and some versions carry extra information — an upper-rack-only indication is common and easily missed.
Indicates that an item can be cleaned in a dishwasher, drawn as plates or glasses in a square with water droplets or diagonal lines falling on them.
Contexts: Packaging
Is not a standardised symbol. No body defines it, its drawing varies between manufacturers, and its presence is the manufacturer's own assurance rather than a certification — so the absence of the mark does not reliably mean the object is unsuitable, and its presence is not a guarantee.
Stated first rather than as a footnote, because it is the most useful thing to know about the mark. Check the manufacturer's own instructions where it matters.
Contexts: Packaging
Sometimes carries a rack restriction — the dishes drawn only in the upper half of the square meaning top rack only, where the heating element is further away.
Easily missed, and the reason an item marked dishwasher-safe can still be damaged.
Contexts: Packaging
May also indicate a temperature limit in some manufacturers' versions, which is one of the reasons the mark cannot be read reliably across brands.
Contexts: Packaging
A square outline containing two or three plate and glass shapes, with short diagonal strokes or droplets falling onto them from above.
Both are unstandardised manufacturer care marks, drawn differently by different makers, and both appear on the same underside.
