Re: The Delay
Some machines had a dual interlock system, others had only one.
For years, Hoover had a the dual system: physically turning the programme dial engaged a mechanical system, which prevented the door button being pressed in. In addition, the bimetallic/heater interlock was also used. This had that annoying time delay.
When the Hoover “New Wave” range was launched in 1993, a different interlock system was used. This consisted of a pneumatic sensor which detected water in the tub, coupled to a mechanical movement sensor which detected rotation of the drum. This system had a “zero-delay”, which meant that you could open the door immediately on finishing.

P.S. (Elephants do not forget)
