Abstract
A method and apparatus for spinning and draining an automatic clothes washer after a wash or rinse cycle. After the water is pumped down, the spin drive and drain pump are activated with an on and off schedule of increasing on times, but constant off times. For example, the spin drive and drain pump may be activated for on times of 10, 15, 20, etc. with interleaved off times of 5 seconds. The off times of the drain pump allow suds in the drain pump to be purged, and thereby increase the steady state flow rate of the drain pump.
