The above laundry procedure is defined as standard wash. The washing machine using the above washing program method has unbalance correction, and a specific method is adopted to detect an unbalance switch of the washing machine during dehydration, wherein the unbalance switch is normally closed, namely, a normally closed switch, and if the unbalance switch acts, namely, the switch is closed after being opened for a short time, the computer controller judges that clothes in a washing machine barrel are placed in unbalance, and performs unbalance correction. Generally, the imbalance correction processing method is as follows: and injecting water to the original set water level after braking to balance the current washing water flow, washing for 60 seconds or 90 seconds, and draining water back to the original dehydration process.
