Turn it on and your last combination is already loaded.
You probably run the same cycles most days, so nuviebaby Clean Max remembers the last combination it actually ran: the wash, whether Steam was on, and how long Dry was set for.
Turn it on and that combination is already loaded, with the total time showing. Tap Power/Play and it runs. The memory survives being switched off. It clears only if the machine is unplugged.
no memory or last-cycle recall feature is documented for nuviebaby Clean (v1). Do not assume the Clean has this feature.
