His Chet. Todd was kind enough to give me this exact 2-speed 1974 LK washer.
The Custom Care button reduces agitation speed from normal to gentle but leaves spin speed unaltered.
When you turn the timer knob (when in the off position, i.e. pulled out) it will stop at the cycle that corresponds to the selection you've made on the piano keys. If no piano keys are selected (which can be achieved by pressing selective dialling cancel) the timer will not stop anywhere and you can just keep turning it round and round.
If the timer is in the on position (pushed in) then you can turn the timer round and it will not stop anywhere. So if you want a shorter wash, you can make your selection on the keys, then turn the dial and it will stop at the appropriate cycle, then push in the timer to start the washer and then turn the timer a few clicks further to shorten the wash. The detergent dispenser runs for the first 4 minutes, so if you skip past that for a short wash, the detergent dispenser won't operate.
I don't know why pre-soak, pre-wash and second rinse are labelled, but perhaps they just wanted to make it clear for the user to see what stage the timer/cycle was up to, just as rinse and spin and wash time being labelled. Maybe they didn't label the other cycle names because the idea what that you would turn the timer and it would then stop at the cycle you'd chosen on the piano keys, therefore negating the need to label the cycles around the timer itself.
If you don't select a piano key, I think it defaults to hot wash on the normal cycle.
