I think mechanical controls are good too! In the seventies Australian Simpson washing machines in the TOL were available as fully programmed, in that a whole row of push puttons had every kind of load listed and you pushed that putton and all parameters were set, you selected water level and switched on. The really TOL has "solid state" controls and you could adjuest the preset parameters too! Kind of a predessesor to todays all electronic models but i think it could still work and provide all the features you would want!
Water saving solid tub too!
I have a photocopy of a newspaper advertisement of this machine, poor quality but I should scan it nonetheless!
