Rising wavy lines, usually over a vessel.
Also known as: Steam symbol, Wavy lines going up, Squiggly lines on an oven
Two or three wavy lines rising from a base, meaning water is being turned to steam. It appears on ovens, washing machines and irons and means the same thing on all three, which makes it one of the more transferable appliance marks.
Two or three wavy lines rising vertically, usually from a vessel or a flat base, indicating a steam function.
What a given programme actually does is in the appliance's own instructions. The symbol names the function; the manufacturer decides how it behaves.
Contexts: Electrical equipment
Consistent across appliance types. The same mark means steam on an oven, a steam-assisted wash programme and an iron's steam control, which is unusual — most appliance symbols do not transfer between machine types.
Distinct from the heat symbol on a hob, which is a similar wavy line but horizontal and beneath a vessel rather than rising from it.
Direction distinguishes them: rising is steam, horizontal beneath is heat.
Two or three vertical wavy lines rising in parallel, usually from the top edge of a small open vessel or a flat horizontal bar.
