How is a washing machine a computer system?

Answer 1

A computer within a washing machine controls many aspects:

The user interface, that is, buttons, LEDs, display, buzzer, are all driven and managed by a computer.

The washing program is controlled by a computer: when to heat the water and how much, when and how to spin, etc. Modern washing machines measure the cleanness of the washing and optimize the washing cycle's duration to wash as long as necessary while completing as soon as possible. Modern washing machines also feature sophisticated spinning and load-balancing algorithms which reduce vibrations during the spinning, thus reducing noise and mechanical stress.

A washing machine's computer will also monitor safety equipment: for example, a frontloader's door must be securely locked before water is allowed in. Water flow must be confirmed, and the required amount of water must be in the machine before the heating is allowed on, etc.

The washing machine's computer will also monitor the machine's general state of health and maintenance. For example, after a set number of hours of active usage, the machine might display a recommendation to replace the drive belt, or to clean the fluff filter.

Answer 2

Not strictly speaking computer- like internet terminals, but electronic computer logic is built into many modern washing machines, electronic timers regulate the speed of the action, by servo action the R.P.M. and cyclic rate (often back and forth or oscillating) and heating and cooling cycle, almost all the newer Maytags have digital LCD displays as you put in the money and give cycle information and time remaining. The electronics age has even impacted the mundane washing-machine! and for the good, as they are more energy-efficient and important demand these days.
