Oven, hob, washing machine and dishwasher controls, described so they can be decomposed rather than memorised. An oven symbol is built from parts — a square is the cavity, a line against an edge is the element on that side, a fan is moved air, a zigzag is the grill — and a reader who learns the components can read a panel they have never seen, which a table of one manufacturer's programme names would not achieve. Several pairs turn on one detail: a snowflake alone means freeze and a snowflake with a droplet means thaw; wavy lines rising are steam and the same lines horizontal beneath a vessel are heat. What no record here does is say what a given programme will actually do, because which functions exist and how they behave is the manufacturer's decision and lives in the instruction book.
A square is the oven, lines are elements, a fan is forced air.
A three- or four-bladed fan: the air is being circulated.
A zigzag against the top of the square: the top element alone, at full heat.
Concentric rings, a dashed outer ring, or a flame: which zone and what kind.
An H, or a lit dot: the zone is off and still hot enough to burn.
Rising wavy lines, usually over a vessel.
A snowflake with a drop beneath it, or a snowflake being melted.
A key, a padlock or a small figure: the controls are frozen.
A leaf, or the letters ECO: longer, cooler, and the tested setting.
A circle with a coiled arrow, and a number in revolutions per minute.
A clock face with an arrow, or the letter h with a number.
A shape with one half shaded: run the cycle on a partly filled machine.
A dial or droplet with a wave: the machine decides when to stop.
A divided tub for pre-wash; a clock or a bolt for a fast cycle.
A star or a sun for rinse aid, and an arrow into a container for salt.
