Ron, the new and more advanced machine these days, Are their timer
movements and duration controlled entirely by a microprocessor and as a
result sometimes it might take a minute to move a notch and other times
it might take 5 minutes? In other words, would a notch in a cotton
wash function take longer to move as opposed to a notch in a wool wash
function? Or in your experience, a notch increment is constant during
a timed event?
By the way, doesn't Brandt sell their machines in UK? My machine is
French-made, but not particularly for the French market.


In a microprocessor controlled machine there isn`t a mechanical timer
-
or I havent seen such a machine if there is. All the functions are
managed by the micro in combination with the power board.

As far as moving on a notch as you put it, in a normal mechanical
timer, the longer programs just have more notches than the short
programs and the heating cycle is longer for higher temps.

The pdf circuit diagram Sam posted appears to be unavailable now, are
you saying your machine has a microprocessor board somewhere? in which
case why would it have a typical crouzet type timer... Is it that you
are confusing the power module with a control module (microprocessor
board)?


Sorry, I must have deleted it by mistake. I'll try to get it back.
