1. An appliance for executing a physical cycle of operation wherein the appliance can be placed in one of a first mode or a second mode that draws less power than the first mode comprising:

  • a control panel having at least one user input interface that, when activated, generates a key press input signal; and

    a controller communicatively coupled to the at least one user input interface to receive the key press input signal and having a clock circuit that is on when the appliance is in the second mode and generates a periodic clock signal;

    a timing circuit that is on when the appliance is in the second mode and receives the periodic clock signal and generates a periodic strobe signal based on the periodic clock signal, and a detector logic circuit that is periodically on when the appliance is in the second mode based on the periodic strobe signal;

    wherein the detector logic circuit is configured to detect the key press input signal when the periodic strobe signal is active and, when the key press input signal is detected, generates a signal that places the appliance in the first mode.
