A method of operating a dishwasher having a treating chamber for washing utensils includes draining, capturing, and storing a portion of a wash liquid multiple times within a single cycle to optimize water savings. Selected pulses are advanced by triggering a leading edge of the pulse at a time one phase-division period before the system clock edge, allowing trailing edges to be extended and providing minimal latency delay. An access transistor is at least a portion of the horizontal semiconductor fin and the access transistor gate. At least one of the flanges comprises a spring finger, which is engageable with a concave portion of the base for fixing the EMI shield on the base without using screws. The scanned data is sent to the computer via the unidirectional interface.
