Is there any chance you could re-scan this please so that we can see the bit that is obscured on the right hand side - even if it means citting off some of the left. It seems to say "Roto-Swirl" agitator and I am guessing that the "On-Off" control was a subsitute for the thermostat control rather than just have a blanking plate on the control panel. No boil washes here I think! Up to 12 minutes wash time, seven pound load, recirculating water, lint removal, it all screams Supermatic to me at least.
