Pic washing machine project

For the interested (future) experimenters on washing machines
(like myself maybe) it might be good to find out what actions
are involved to get the overall control idea.
Will someone correct and add, to the next primitive setup: (?)
Greetings, At v.W.
out0 sound beep (alarm)
out1 motor spin direction
out2 motor speed
out3 motor on/off
out4 heater element on/off
out5 water inlet valve on/off
out6 water outlet pump on/off
in0 start button
in1 heater temp sensor
in2 water level sensor
in3 centrifuge yes/no
in4 long/ short wash
in5 watertemp set1
in6 watertemp set2
var1 tflag ; max temp reached
var2 wflag ; max waterlevel reached
Start button sensed:
read several selection switches
(or get rs232 info) not used yet
clear tflag and wflag
gosub startup; gosub spin
if wflag and tflag are set then return
else goto startup
check for max waterlevel
if max then close watervalve; set wfag
else open watervalve
if max then switch heater off; set tflag
else switch heater on
for time = 1 cycle
spin right; wait 1 sec; spin left
spin right during 2 min; wait 10 sec
spin left during 2 min; wait 10 sec
loop during 30 min
switch heater off
start pump for water outlet
if no wool selected
then centrifuge for x minutes
